|Nov-07-05|| ||ray keene: maybe i shd have played 17---nxc4 throwing another piece into the mix-anyone with a computer out there??|
|Dec-04-05|| ||aw1988: It looks sound. I'm not using a computer but Nxc4 Qxc4 Rb4 Qd3 Rd4 wins the bishop.|
|Feb-16-06|| ||who: Fritz thinks 17...Nxc4 is the best move leaving black with a solid advantage of 1.15 pawns.|
|Feb-16-06|| ||ray keene: <who> yes i found this later myself-its amazing that black can sac another piece while already one down|
|Apr-04-06|| ||FrancisGrasso: aw1998, White has the better 19 Qe2!
saving his material after your 18...Rb4? Yet Black improves with 18...Qxd2! winning his piece back, since he's hitting the c3-knight, and still attacking the bishop, and 19 Nb1 is answered by 19...Qd4+!
Have a nice day.
|Oct-05-13|| ||al wazir: 27. Rxc4 wins equally well.|
|Oct-05-13|| ||offramp: Very very good! Great play from GM Keene.|

|Oct-05-13|| ||LIFE Master AJ: 12:26 AM Pensacola, FL time.
I probably used more than 20 minutes, I also lost track of the time.
I was totally stumped, I tried 23.Rf6!? (I could not find a 100% concrete follow-up.) The idea was to play 24.Bh6, (with mate to follow); however, Black's position is not without resources.
|Oct-05-13|| ||LIFE Master AJ: OK, I was on the right track. Apparently, I got as far as Black's 27th move, but just missed the simple 28.RxP/f7+! (I must be tired or getting old.)|
|Oct-05-13|| ||LIFE Master AJ: <offramp> Did you realize that Keene lost this game?!?!?|
|Oct-05-13|| ||Jausch46: I think there was a quicker mate by 27. Bxg7, anything, 28. Bf6 discovered check, Kf8 29. Rg8 checkmate. GM Sugden missed it in the heat of battle, or may be I am wrong?|
|Oct-05-13|| ||LIFE Master AJ: Ray - Thanks for showing us a great game. It often takes two very strong players to produce a beautiful game of chess!!!|
|Oct-05-13|| ||Kikoman: Too easy to solve our <Puzzle of the Day>. ;D|
|Oct-05-13|| ||An Englishman: Good Evening: I saw that White had to deny the Black Queen the h6 and g6 squares, deny the Bd7 the f5 square, and that the same Bishop had no protection, and came up with 23.e6. I feel unusually tactically blind even by my own standards--what did I miss?|
|Oct-05-13|| ||Gilmoy: <An Englishman: 23.e6> Black can just sac the piece: 23..Kh8 planning f6-Rg8, and/or Qd6 to force White's Q to hop. Assuming Black eventually overwhelms the d7-pawn, he'd be down B for PP, but with some counterplay.|
23.d6 is even worse (for White), since it doesn't even steal a piece.
But <23.Rf6> can't be ignored: Black's Q must run/hide, <and> she must stop the implied mate(-in-2) -- and she can't.
<deny the Bd7 the f5 square, ...> The Nh4 is already doing that. So just don't move it. (But: see if moving it smites winningly.)
|Oct-05-13|| ||DWINS: <ray keene>, I submitted the game to computer analysis and your idea of 17...Nxc4! definitely wins. Stockfish 4 gives the best line as 18.Qxc4 Qxd2 19.Ne2 gxh5 20.Qc1 Qxa2 (-3.03).|
Stockfish disagrees with your comment on move 20 and gives 20.Qxc4 Qxd2 21.Nf3 Qb2 22.Qxc5 Qb6 23.Qxb6 Rxb6 (-0.38). Instead 20.Bf4! is the correct move giving White a winning advantage after 20...Nb6 21.Qg3 Kh8 22.e6 (2.10).
Lastly, 21...Nb2? is the losing move. Black could have salvaged a draw with
21...Nxe5! 22.Qg3 Nc4 23.Ne2 Bg4 24.h3 Bxe2 25.Nf5 Qc3 26.Nxe7+ Kh8 27.Qxc3 Bxc3 28.Rxe2 Bd4+ (0.00). This is very complicated and there are many interesting alternatives White could have played, but the end result according to Stockfish should be a draw.
Thanks Ray for annotating this interesting game. Many GMs never comment on their losses.
|Oct-05-13|| ||DWINS: <An Englishman>, <Gilmoy>,
23.e6 allows Black to draw.
23.e6 fxe6 (23...Kh8? 24.exd7 (8.22)) 24.Rxf8+ Rxf8 25.dxe6 Bxe6 26.Bh6 c4+ 27.Re3 Rf7 28.Bxg7 Rxg7 29.Qe5 Rg4 (0.00)
Although not as good as 23.Rf6!, 23.d6 wins handily after 23...Kh8 24.Nf5 (3.75).
Analysis by Stockfish 4
|Oct-05-13|| ||morfishine: I didn't consider 23.Rf6. What I did see was <23.e6> failing to see that Black holds after 23.e6 fxe6 24.Bh6 Rf7|
Poor effort by me today :(
<DWINS> Good points that refute 23.e6
|Oct-05-13|| ||diagonalley: i tried 23. P-K6 too... but black can wriggle out of it... dammit|
|Oct-05-13|| ||Once: Missed it, but I spotted an interesting inferior alternative. Well, I think it's interesting...|

The idea is the same as in the game. We want to block the sixth rank so that we can play Bh6. It's not as forcing as 23. Rf6 as we are not immediately threatening anything. So black has time for 23...Kh8. But then we pile on the pressure with 24. dxe7 or 24. Bxb2.
It's not immediately winning (and certainly not as good as 23. Rf6), but I'm having fun.
Fritzie improves on my lines (of course!) with 24. Nf5

... and we have a nice little kingside attack brewing. Herr F calls it +2.68 after a few minutes soliconsideration. I'd settle for that in real life, whilst wishing I'd spotted 23. Rf6.
|Oct-05-13|| ||Caissas Clown: Re"Not many people get to commentate at their own funeral."
Ha ha !
It's a British thing , radtop - as Ray Keene demonstrates , we pride ourselves on our magnanimity.
After recognising the theme of cutting off the Black Q ,I considered ,but quickly dismissed,the incorrect 23 e6 ?
I then found 23 Rf6 !! fairly easily, though must confess,I carelessly failed even to consider 23 d6.
You have to feel sorry for John :
23 Rf6!! is a terrific move , but will probably never get the same admiration as 19 Rf6 !! here:
Fischer vs Benko, 1963
|Oct-05-13|| ||offramp: I now realise that GM Keene lost this game. I repent in dust and ashes.|
|Oct-05-13|| ||patzer2: Got the first two moves 23. Rf6!! exf6 24. Bh6, but had difficulty visualizing the follow-up to this Saturday's puzzle.|
Black resigns in lieu of 32...Kd8 33. Qd7#. If 29...Qxe6, to prolong the game, the quickest way to mate appears to be 30. Qg7+! Ke8 31. dxe6 .
|Oct-05-13|| ||Sho: "Thematic Match" What does that mean? Thanks.|
