Austin’s Chess Diary Snippets

I’ve decided I might stick short chess-related snippets here, in order for them not to clutter up the blog pages. (Assuming I ever get around to adding any new posts…. ).

This new page is partly because I’ve found myself posting these chess snippets on Facebook now and again for the chess club ‘wall’, and I thought my scientific chess friends might be interested too.  These will mostly be (hopefully) interesting or amusing (that latter term will only apply to chess fans!!) positions or problems from games, maybe with the occasional “What happened next?!”

So here goes:

Diag 1: White to play and win



This one comes from a 10 minutes-a-side game last week. It is White to play:

Now, I REALLY wanted to sacrifice something on b7. In my mind there was a variation that ran:

1. Rb7:! Kb7: 2. Rb1+ Ka8 3. Qc7 threatening unstoppable mate on b7, or 2. …Kc8 3. Ba6+ Kd7 4. Rb7+

HOWEVER… there is a rather obvious snag with this brilliancy. Can you spot it?

I actually picked up the R on b1 and was half-way to b7 when I realised what was wrong. Luckily my opponent is a gent and we don’t play touch-move in casual games. So I got to have a re-think. However, there are actually at least two quick forced wins for White in this position. For one of them the first move (which I spotted and played after I’d ‘undone’ 1. Rb7:) is fairly easy, the continuation a bit less so, but quite pretty. Suggestions?

BTW, if you are a non-chesser who has strayed here, and is mystified by this idea of timing chess games or ’10 minutes for your moves’, Dominic Lawson (yes, that Dominic Lawson) explains in an article here.


Ten-minutes-a-side for all your moves is a common way to play casual club chess, suitable even for us older gents.  When I was a teenage chess fiend, I used to play endless 5 minutes-a-side games (5 minutes to make ALL your moves, sometimes known as ‘Blitz’), notably in my school lunch hours. However, I now find that 5 min is just TOO fast – ageing synapses, I guess.

The quicker you have to make all your moves, of course, the greater the potential for tactical oversights. To show just what a lottery a 5 minute-a-side game can be with players as bad as me, here is a comedy of errors from Tuesday night:

Diag 2: White to play

It is White to play.

The game actually finished: 1. Nd5: Nd5: 2. Nh6+? Kh8?? 3. Nf7:+ Black resigns.

What had both players missed?









21st June – STOP PRESS:

Playable chess board…. well flash!

Our resourceful blog overlord RPG tells me we now have a “Chess Flash” plugin installed, hopefully enabling you to actually play through games that I post up here on a virtual board! As a test, here is one of my ‘time handicap’ rapid games from a club tournament last month. Since I had a whopping 16 minutes thinking time to my opponent’s (distinctly meagre) 4 minutes, you could call it a bit of an uneven contest, though he is rated rather higher than me, and is an excellent rapid player.

Anyway, let’s see if the plugin works! I am playing Black.

[Event “Club Mayday rapidplay tournament”]

28th June

I played a (Summer) League game on Monday night, so by club night on Tuesday I was a bit “chessed out”. We spent most of the evening analysing games people had played the previous week or at a local chess congress at the weekend, rather than actually bashing out the rapid games. So I’m slightly stumped for a interesting ‘what happened next?’ problem for this week. But here’s an easy-ish one, from a 10 min-a-side game a month or two back.

Diag 3: White to play

One of the things I’ve noticed since starting to play chess again, and which I think is directly attributable to the ubiquity of computer chess and playing online, is that tactical awareness has gone up a lot. People play much more for tactical combinations, and far less for strategic objectives. This is quite noticeable in normal time-limit games (where you have, say, 65-95 minutes to make all your moves), so it is all the more noticeable in rapid games (10 minutes or less for all your moves), which are always more tactics-based. Trying to grind out a logical strategic victory in a 100-move marathon is a high-risk strategy in speed chess, as there is a good chance you lose on time whilst trying to make your extra pawn count in the endgame.

Now, I had to try and remember this particular game afterwards (You don’t usually record moves when you only have 10 min to think of them all in!), so I am not 100% sure whether the Black pawn was on b4 or b5…  though it’s not a critical point.

White – me – is clearly better in this position, which chess aficionados will spot as arising from a typical open Sicilian set-up. Objectively, White probably needs to protect his c2 square before embarking on any adventures. However… it’s a 10 minute game, and as this was around move 20 we were probably down to under half that time. So direct threats are hard to resist. Anyway, I went for:

1. Rh3  (threatening Qh7:+, obviously)

– and the game continued

1.         …h6

2.  Rg1 Kh7

So the easy question:  how did the game now finish?  And a slightly more taxing one; could Black have played better moves than  1. ..h6 and 2. …Kh7?

A Tricky End (ing)

Diag 4: White to play

For something a bit more refined, I can’t resist sticking up this one, which we were kicking about on the Club Facebook page last week. I should say that it wasn’t me that posted this there, but one of my club sparring partners, local historian and author Graham Phythian. He tells me that it is a 1985 problem study by one H. Valkevitz. Now, normally I don’t care much for composed chess studies, as they often show positions it would be utterly impossible to get in a real game, which I find rather dims my interest in them. This one, however,  would be at least be feasible as a ‘real’ endgame position. White has Queen and Bishop vs Queen and Pawn, but the Pawn is only one square from becoming a Queen.

As Graham says, White’s first move is fairly easy to spot, but there are many ways for White to draw, and only one way to win.




8th July – mixed results…

Two games in the Summer League now gone, with one win and one loss. The loss (last week) was a bit frustrating –  partly because I’d previously lost to the same 154/1900-ish graded opponent in the Winter League, so I was hoping for revenge, and partly because I got a better and perhaps even winning position and then blew it in time trouble.  I might put the game up with some annotations when I have time.

Meanwhile, here is another rapid-play puzzler, from a 10 min game (well, 10 min for me and 15 for my opponent) played after my League loss last Tuesday. This one comes from a Sicilian Dragon Yugoslav Attack.

Diag 5: White to play

Now, in this position Black (me) has earlier sacrificed the exchange (R for N) but without getting much compensation, though the White King’s position is a little bit draughty. Anyway, White is trying to consolidate and convert his material advantage. First question, what moves should White consider to consolidate and why?

In the game White actually played 1. Ra7, and I replied 1. …Nxe4?!  So the next question: what do you think happened next? And was 1. …Nxe4 Black’s best shot?


11th July – a game…

I didn’t have a league game this week, but made it down to the club later on yesterday for some kibitzing and a few rapidplay games. Here’s one of the latter:

[Event “15 min game”]
[Date “2012.07.10”]
[White “KS”]
[Black “Austin”]
[Result “0-1”]
1. e4 e5 { I am not usually a 1. …e5 player, but I was tired of defending the Black side of my adversary’s favourite Sicilian Grand Prix Attack. } 2. Bc4 Nf6 3. Nf3 Nc6 { The Two Knight’s Defence. In many of the main lines this works out as a kind of counter-gambit, where Black gives up a pawn to get ahead in development. } 4. Ng5 d5 5. exd5 Na5 6. Bb5+ c6 7. dxc6 bxc6 8. Be2 h6 { All well-known theory. } 9. Nf3 { Bobby Fischer revived the strange 19th century move 9. Nh3 here, including in a famous game against Arthur Bisguier annotated in Fischer’s ‘My Sixty Memorable Games’, but the move has never really caught on. } e4 10. Ne5 Bd6 11. f4 { 11. d4 is more common } exf3 12. Nxf3 O-O 13. Nc3 Re8 14. O-O Qb6+ 15. d4 Be6 16. Nh4? { Heading for f5, but probably a waste of time. Fianchetto-ing the QB with b3 and Bb2 was the obvious alternative } c5? { 16. ..Be5! } 17. Na4? { 17. d5 c4+ 18. Kh1 Bd7 with some advantage to White since Black would not really have enough compensation for the pawn. } Qc7 18. dxc5 Bxc5+ 19. Nxc5 Qxc5+ 20. Kh1 Rad8 { 20. ..Nc6 was an alternative. } 21. Bd3 Bg4! 22. Nf3 Nc4 { Heading round to e5. White is now pretty tied up. } 23. h3 Bh5 24. Re1 Ne5 25. Rxe5 { White was relying on the tactic in this and his next move, both of which I’d missed, to free himself, but the second part of the combination is a mistake. On the alternative 25. Be3, Qc8! is a good response, which I’m quite sure I wouldn’t have spotted. } Rxe5 26. Bh7+? { He should play the only-computers-would-spot-this 26. Qg1! when ..Bxf3 27. Qxc5 Bxg2+ 28. Kxg2 Rxc5 29. Be3 when the Bishop pair and the 3-1 Q-side pawn majority would give White decent drawing chances. } Kxh7 27. Qxd8 Bxf3 28. Bf4? Qf2? { Missing 28. …Bxg2+! which leads to mate. Now things take a bit longer. } 29. Qd3+ Be4 30. Qg3 Bxg2+ { Swapping Queens would win too, but as I was down to a minute left I wanted to keep the Queens on and play for checkmate. } 31. Qxg2 Qxf4 32. Rf1 Qh4 33. Qf3 Rg5 34. Kh2 Ng4+ 35. Kh1 Ne5 36. Qe3 Rg3 37. Qf2 Qxh3+ 0-1 {  It is mate next move.  }

And finally, also from Tuesday, another little puzzle, taken from a different rapid game (not too hard):

Diag 6: Black to play


White has just responded to the threat on f2 by playing his Knight from h2 to f3.

First question: what SHOULD White have played?

Second question: what does Black play now? And what happened?








Moving on a few moves in the game over the board (and giving away the answer) we reached the following position (Diagram 7):

Diagram 7 – from a few moves later – Black to play. How does Black finish White off neatly?

There is now a neat finish leading to checkmate or win of even more material. Can you spot it?

    Seems to me from a quick glance that you must have missed the black Q x b1 as the defense against your rook sacrifice after having played Re1 to b1. On the other hand, by my limited calculations, and I may be missing something as the phone keeps ringing, it seems that the correct sequence for winning would be Ba6. If b x B on a6, then the white Q comes to c7, threatening mate with the Q on b7. Even if black R comes to b8, then white Q take b8#. If black doesn’t take the sac by b x a6, then B x b7#.

    I’ll try the second one later. Thanks, these are fun for a retired chess lover…

    • Hi Steve. Yes, you’re right that what I missed was that the Black Q was covering b1!!

      Actually, it’s possibly a bit more interesting than just ‘oh *!**!’, because for most of the game I’d had doubled c-pawns, with pawns on c2, c3 and d4. Of course, if there was still a pawn on c2 in the position, then Rb7: and Rb1+ would be a nice simple mating finish, as the b1 square would not be under attack by the Black Q. I think maybe part of my ‘chess brain’ still ‘residually’ thought the pawn was on c2, so that the b1 square was ‘safe’.

      Plus, of course, you ALWAYS want to sac a Rook on b7 when the b-file is open and Black King has hidden on the Q-side! See e.g. the old game I gave in this post.

      On the 1. Ba6 idea, agreed that 1.. ba: 2. Qc7 is terminal. So it has to be 1… Rb8 or 1. ..b6. After 1. ..Rb8 I’m not sure that 2. Qb8:+ Kb8: 3. Rb7:+ actually wins by force after either 3. ..Ka8 or ..Kc8 – mainly because the Black Q is covering e8, so you can’t play 4. Re8 mate. And after 1. Ba6 Rb8 2. Qc7 Black can play ..b6, when again I can’t see an instant mate.

      Anyway, it turns out to be a surprisingly interesting litte position.

      The second one is a lot more straightforward, and far more embarrassing for both players!!

      • Steve Caplan says:

        Austin, I see your point. But–as far as I can see, after Ba6, Rb8 loses for black, because of B x b7 which forces …R x b7, followed by Qe8+, …Q x Q and R xQ forcing mate. On the other hand, for black this CAN be prevented by b6 which won’t give white the open file to force the mate.

        I now see (I think) that for white Q c7 is the correct sequence and wins. Re8 is the only defense, black won’t have time to play Rf7 because he has to play Rb8, which can then be followed by Ba6 and I think black will be in trouble.

        As for the 2nd game, perhaps I’m missing something, but I don’t see why black can’t simply take the knight with g7 x N. True, white will have some pressure, but losing a knight for a pawn and then another knight, I think black can withstand the attack by defending with Bg7.

        • Hi again Steve

          1. Good spot on 1. Ba6 Rb8? 2. Bb7:+! forcing mate after 2. …Rb7: 3. Qe8+. Another one that I’d missed. But as you say, 1. Ba6 b6! is a tougher nut to crack: if 2. Qc7, then…Rb8 seems to defend.

          2. Once one ‘rejects’ 1. Rb7: (and possibly 1. Ba6) then 1. Qc7 is the obvious move, I think. 1. ..Rb8 is forced (as you say). In fact this is what we played in the game, but Black lost on time before I could play my next move. I’d been looking at 2. Ba6, but if 2. Ba6 b6! we get back to the same position as after 1. Ba6 b6 2. Qc7 Rb8, where it’s not obvious how White can break through and the counter-threat of …Nf4 looks troublesome.

          There is, though, a different and rather pretty clear winning move for White after 1. Qc7 Rb8, which I only spotted when analysing after the game.

          3. In the second game, Black didn’t take the Knight on h6 because he (and White, which was me) both assumed that after (1. Nd5 Nd5: 2. Nh6+) …gh: the game would finish 3. Qg4 (or g3) check, forcing 3… Bg7 and then 4. Qg7: mate. But we’d both missed a rather important and embarrassing detail.

          A clue is that if the White pawn was on f4 instead of f3, then the combination with Nh6+ would actually be sound. Amazing what a difference one square can make…

          • steve caplan says:

            Thanks for not giving it away! I have been musing about the solution en route to a Gordon conference today, on and off between and on flights. Without the benefit of having a chessboard and being able to check it out, I am pretty certain that after Qc7 …Rb8, white wins by the sac at R x b7. This forces R x R, otherwise white has R x b1#. Following this, white has a series of variations, and I haven’t worked them out in their entirety, but I am pretty sure that Qc8+ followed by …Rc8 and then Q x c6+ …Rb7, Qc8+ …Rb8 and now the bishop can enter the fray with Bd5+ and it’s downhill thereon for black. Still haven’t looked carefully at the second one, but will get to it probably next weekend!

          • Austin says:

            Good try, Steve, but no cigar, I fear. The Rb7: and Queen checking on c8 and c6 idea is quite a thematic one in similar positions, since if the c6 pawn goes it is definitely all over for Black. However, the fly in the ointment here is that the c6 pawn is protected by the Black Rook and Queen along the 6th rank, so can’t be taken…

  2. Steve Caplan says:

    Ha! Good thing I don’t smoke cigars! Truthfully, I don’t see it, but can’t help thinking that it’s still R x b7 followed by Qc8+ and then something with that bishop. When I get back home I’d like to try on an actual chessboard. I know that’s “cheating” for you higher ranks, but after several moves in my head I’m not “seeing” the new board as it should be. Guess that’s why I didn’t get past the 1400 rank!

    • Austin says:

      I’ve never really been able to ‘see’ the (a few moves ahead) board in my head the way one assumes people who play blindfold chess can do, which probably explains why I ‘max-ed out’ as a player at 2000-2100. Don’t know whether it is something one can learn, at least up to a point, but some players do seem to have an innate ability to do it.

      Being about to play multiple simultaneous games ‘blindfold’ always struck me as the single most startling thing that many chess masters can do. Blindfold chess has actually been the subject of an entire scholarly history written by Eliot Hearst, a Psychology Prof (now retired) who is/was also a chess master in his young days. I’d quite like to read the whole book (as opposed to Google snippets), but the whopping price tag is a bit of a disincentive.

      Going back to the problem, try looking at it this way. After 1 Qc7 Rb8, we know that if the White Rook could reach e8 without being taken then we could checkmate Black at once with 2. Qb7:+! Rb7: 3. Re8+ and mate on b8… except it doesn’t work, because the Black Q is guarding e8 from her post on g6. So is there any crafty way we can decoy the Black Queen away from the defence of e8?

      BTW, most of my best ideas come from analysing with a board and pieces after the game, trying to see all the good moves I’d missed! I think this is the chess version of the famous Esprit d’escalier.

      • Steve Caplan says:

        Actually that’s the first thing I looked for! I wanted to bring B to d3 to get the black Q off the e8 square but I got stuck with the Q moving to f2 forcing an exchange of queens. That has to be the answer, burnt visualization skills are lacking without a board to see how that plays out!

        • Austin says:

          Correct. 1. Qc7 Rb8 (forced) 2. Bd3! and then if 2. ..Qf7 3. Re7 should decide – e.g. if 3. … Qf8 to cover e8, then 4, Rb7: and mate next move, or if 3. …Qa2: then e8 is unguarded so 4. Qb7:+! forces mate.

          3. Re7 is one of those moves that you would spot instantly if shown the position after 1. Qc7 Rb8 2. Bd3 Qf7, but which is much harder to spot ‘envisaging’ the position in one’s head two moves ahead, at least for us ordinary Patzers.

          After 2. Bd3! I think Black’s best try is 2. …Rf7, but 3. Bg6: Rc7: 4. Bh5: just leaves White a Bishop up.

          Actually, it turns out that 1. Rb7:! actually wins as well, provided White DOESN’T play 1. ..Kb7: 2. Rb1+??, but finds a different (and much better!) second move…

  3. Stephen Moss says:

    Austin and Steve – finally gave myself time to read through all your comments and analysis, and regret only that I couldn’t have joined in earlier. Usual feeble excuses of grants to submit, papers to write/review etc.,

    • Well, there’s still time…

      We haven’t yet identified the winning line after 1. Rb7: Kb7:

      Or explained why the second game is so embarrassing for both Black AND White!

      BTW, I’m hoping RPG might set me up a chess plugin which would give ‘playable boards/games’, which would make the chess stuff a little more accessible.

  4. Steve Caplan says:

    COOL! Thanks to our warlord! Or is it overlord? Anyway, that will make things so much better. Although I’ll have to be careful not to get addicted now…

  5. Steve Caplan says:

    Just had a quick peek at your blitz game; I like white’s development until cxd5, which seems bad for white, and then the Q side castle, which had no real point when black had already castled and had the R protecting your Q on the back rank. The castle got white into a series of weak/questionable moves that allowed you to move in for the kill. Nice!

    • Thanks Steve. If I play those Saemisch-type positions with White I like to close the centre with d5 before I castle Queenside and start a standard Kingside attack w h4, g4 etc. If White allows exd4, the position takes on more of a Sicilian Maroczy Bind character, when the White K definitely belongs on the Kingside.

      The Dragon Variation where Black plays the analogous …d5 move has White castled Queenside, as here, but with the critical difference that White’s c-pawn is on c2, not c4. This makes the White K quite a lot more secure. Accepting the sacrifice on d5 when both c-pawns have already gone must be a bad idea – Black gets far too many open lines for his Rooks, Queen and Bishops, and White has too few defenders.

      [BTW, the ‘book’ set-up for White after 10. cxd5 cxd5 in the game would be 11. e5 and then to play something like f4, Bb5, Nf3 and O-O]

  6. Steve Caplan says:

    Although I just dabble here and there, now, this is a 5 min. blitz game online with R.V. playing white and me with the Karo Cann in black:

    [pgn]1.e4 c6 2.d4 d5 3.e5 Bf5 4.h3 e6 5.Nf3 Nd7 6.g4 Bg6 7.h4 h6 8.h5 Bh7 9.Be3 Qb6 10.Bc1 Ne7 11.Nc3 c5 12.dxc5 Nxc5 13.b3 Rc8 14.Bb2 Nc6 15.Bb5 a6 16.Bxc6+ Rxc6 17.Qd4?? Bxc2 18.Qd2 Nd3+! 19.Kf1 0-1[/pgn]

    Happily for me, I was finally able to take advantage of some weak moves by the opposition and a distinct positional advantage to leverage it into a winning situation (rather than squander it, as is my tendency. This position then wins any number of ways, for example Bb4 and pushing the white Q off the 7th rank and protection of Qxf2#, or slower wheedling down of white’s pieces.

    But it shows that it’s enough for several weak/slow moves followed by a strong attack to win a game, as long as the better positioned player is capable of taking advantage of the momentum (something I’m notoriously bad at doing, otherwise my rating would have been higher…)

    [EDIT: I’ve turned this into a playable game – Aust]

    • Austin says:

      Nice thematic stuff. I used to play the 3. e5 advance line against the Caro as White back in the day, with mixed success. Don’t like your opponent’s 4. h3 – if the P goes to h4 later (see his 7th move) it takes two moves when it could have taken one, so wastes a move for nothing.

      Here’s one old one in the line with me playing White, in the 1975-6 London U-16 Championship (sic). We were both graded in the mid-130s ECF, so c 1700 FIDE if you believe the conversions. It was the 11th and last round, on the 6th day of the tournament, so I dare say we were both a bit battle-fatigued. Or even desperate to go home.

      [pgn][Event “London U-16 Ch 1976-7 rd 11”]1. e4 c6 2. d4 d5 3. e5 Bf5 4. h4 { The Caveman Attack, as mentioned by Steve Moss } e6?? 5. g4 { Uh-oh… } Be4 6. f3 Bxc2 7. Qxc2 {and I eventually managed to win with the extra Bishop in 24 moves} 1-0[/pgn]

  7. Stephenemoss says:

    Great to have these playable games. I play a fair bit of on-line chess but rarely encounter the Caro Kann. When I do, I usually try the caveman attack, which is a lot of fun and perhaps not so well known, so can catch out the unwary.

    • Austin says:

      There’s an article on the Caveman Attack here, which mentions the Rook sacrifice (letting the Black Q take on b2 and then on a1) which I’m sure I remember Steve M alluding to at some point.

      Nowadays I’m so boring as a player that I’d probably play the Exchange Variation against the Caro.

  8. Steve Caplan says:

    I really like the Caro Kann, (despite never remembering if it’s C.K. or K.C.) because it severely limits the scope of white’s options. All the Sicilians are of course gone, and although I fared relatively well against most of these, I never learned the theory and just don’t have the time! 90% of players respond to CK with the advanced variation, for which I am reasonably prepared, and I would normally meet h4 with h5 or h6 top avoid the bishop trap.

    Thanks for putting the game into playable format and “immortalizing” it for me! I’m a slow player so I almost never do well at blitz….

  9. Austin says:

    I never really came to a firm decision as to what to play against the C-K. Looking over my old games I see I started off aged 14-15 playing the Caveman Attack, then switched to the Exchange Variation the following year, and a year later again played 2. d3 and switched to a King’s Indian Attack type set up – but we’re talking not much more than a half dozen games in all. And in rapid games down at the club these days I usually seem to end up with the White side of the Panov-Botvinnik Attack against the C-K. So you could call that ‘confused’.

    I do OK at 10 min-a-side games, mostly, like in the club rapid play. But I’m utter rubbish now at 5 min blitz, which is what I primarily used to play in my teens. I shall plead “Ageing Neurones”.

  10. Alexandros says:

    Hi Austin,

    For the last one:
    Initially I thought 1…Nxf2 but 2.Qg6 1-0
    So 1…Qf6 2.Re5 (forced) Nxf2 followed by something like 3.Qe3 Nxh3 4.gxh3 Qxf3 or
    3…d4 4.Qxf2 Bxf3

    White should have played Qd4 that prevents a mate attack and covers f6 square.

    • [NB This refers to Diagram 6 in the post]

      Hey man.

      First, agreed Black should have played 1. Qd4! last move, covering f2 and threatening mate on g7. 1. …Rf7 2. Rxf7 Qxf7 is forced. when White can probably even take the a7 pawn with some advantage.

      1. ..Qf6, as you spotted, is the move for Black in the diagram, forking the White rooks. The only defence is your 2. Re5, when I would have expected the sort of line you gave, 2. …Nxf2! 3.Qe3 Nxh3+ 4.gxh3 Qxf3 5. Qxf3 Rxf3 and you’d reckon Black should be winning the ending, though it would still take a bit of work.

      In fact, after 1. ..Qf6 my opponent played 2. Rxb7?? and the game continued 2. Rxb7 Qxa1+ 3. Kh2? (3. Qf1 is better, though it leaves White the exchange down) Nxf2 4. Qg6. So a follow-up Q: How can Black finish White off neatly after 4. Qg6? (Diagram 7, above)?

      PS NO CHEATING with Fritz!!

      • Alexandros says:

        No cheating with fritz!!!Just Houdini and Stockfish 🙂

        Anyway,I am still at uni so I will try without a board (very difficult for a patzer…) and without any program.
        2.gxf3 Qh1+ 3.Kg3 Qg1+ 0-1

        If 2.Rxg7 Qxg7 3.Qxg7 Kxg7 4.gxf3 then Black is a rook up so 0-1

        Another interesting move is 1…Qxh1 but I cannot calculate any mate attack, which probably exist. I will leave this task to my silicon friend at home 🙂

        • You picked the same move as I did in the game, Alexandros. The only ‘extra’ nuance is that White can interpolate a crafty Queen check on e6 after 1. ..Rxf3 – 2. Qe6+ Kh8 3. gxf3: But, although Black doesn’t win the Queen in that line, it’s OK because then 3 ..Qh1+ 4. Kg3 Qg1+ 5. Kf4 (or h4) Qg5 is actually mate!!

          1. …Qh1+, as you say, is the alternative, and is more ‘forcing’, especially since 1…Qh1+ 2.Kg3 Rxf3+! 3.gxf3? Qg1+ wins the white Queen as before. This was the line the club’s star junior player (age 14 and a half, grading a terrifying 2000-ish FIDE) suggested. I did point out that you’d have to be convinced that if White plays 3. Kxf3 (rather than 3, gxf3?) then his King will get hunted down and mated after 3. ..Rf8+.. Of course, my young friend had probably calculated the mating line, which I’m sure is well beyond me.
