| May-04-12 | | Memethecat: Yes, 27...Qd8 looks pretty solid. Maybe someone that enjoys playing with engines can try & refute it, but I've tried lots of moves on chess viewer & cant find anything significant for white. |

| May-04-12 | | CHESSTTCAMPS: White is down a pawn, but black suffers from an uncastled king with a rook trapped out of play. This make the back rank and both rooks vulnerable, suggesting additional measures to pressure e6 and undermine Rc8. I waffled between the immediate 25.Rd6 and 25.Bd6, finally choosing 25.Bd6!
The DSB is the better defender, so eliminating it further weakens the back rank, gives the N access to c5, and leaves black an overloaded LSB. Passive defense of the bishop loses material: A) 25... Re8? 26.Bxe7+ Rxe7 27.Rd8+ Re8 28.Rxe8+ Kxe8 29.Qb8+ wins. B) 25...Qf6 26.Rxe6! Qxe6 27.Bxe7+ Kg8/e8 28.Bh4 defends e1 and leaves white with B+N vs rook and the BK still in a bad position. C) 25... Bxd6 26.Rxd6 (threatening Rxe6 winning) Re8 27.Rxa6 and the double threat of Ra8 and Nc5 looks winning. Black can't play 27... Bc8 in view of 28.Rxe8+ Kxe8 29.Qb5+ Bd7 30.Qe2+ winning the BQ. Maybe I've missed something better - time for review.... |

| May-04-12 | | JG27Pyth: @meme the cat<Yes, 27...Qd8 looks pretty solid. Maybe someone that enjoys playing with engines can try & refute it, but I've tried lots of moves on chess viewer & cant find anything significant for white.> sevenseaman put a link to the crafty position trainer -- (it's colors reversed) you can try Qd8 against crafty... I played around with it for a while it's pretty interesting. It's definitely better than the text... but calling it solid is a bit much. Crafty gives a convincing demonstration of the superiority of a N+B over R in this position. It's a struggle to get the a-Rook into the game, and by the time you do, Crafty has coordinated his pieces so well, one can't manage any counterplay at all. It's becomes like Napoleon's retreat from Moscow... just because it takes awhile doesn't mean the end is ever in doubt. But I haven't checked the position engine v engine... silcon almost always finds resources that ever elude me. |

| May-04-12 | | polarx: Just like Voodoomoves four years ago I thought the line 25. Nc5 Bxc5 26. Qxc8+! Bxc8 27. Rd8# was beautiful. But the white rook on d4 is pinned. |

 | | kevin86: A nice ending...a bit over my head. |
|
| May-04-12 | | Zatrikion: Not quite sure for this:
25.Rd7 Bxd7 (forced. 25… Re8 26.Rxe7 Rxe8 27.Qb8+ Re8 28.Bd6 1-0)
26.Qxd7 Re8
27.Rxe7 Rxe7
28.Qd8+ Re8
29.Bd6+ Qxd6
30.Qxd6+ and Qxa6
Endgame Q+N vs 2R and white have 2 pawns on the queenside. Time to check if that was the best attacking solution. |

| May-04-12 | | David2009: Gelfand vs Salov, 1996 White 25? 25.Rd6 GOOT! The immediate threat is 26.Rdxe6 and if 25...Re8 26.Qc6 keeps up the pressure. Time to

White played 25.Rd7 which is much stronger. Time to set the position up in Crafty End Game Trainer (interactive link:

My line 25.Rd6 fails to 25...Re8 26.Qc6 Qg4 etc. The main line is 25.Rd7 Bxd7 26.Qxd7 Qb6+ 27.Kh1 Qd8 when the EGT defends with 28.Rxe7 Qxd7 29.Rxd7 h5. Using <sevenseaman>'s excellent interactive link http://www.chessvideos.tv/endgame-t...

35.Kg1  ...leads to wining position/endgame for white. |
|
| May-04-12 | | hugogomes: I saw 25.Rd6 which is also good. |
|
| May-04-12 | | zakkzheng: I guess Valery Salov was hoping for back rank checkmate with Re1# |
|
| May-04-12 | | Jambow: Considered rook d7 just couldn't bring it home, oh well tough position and credit to Gelfand. |
|
| May-04-12 | | Abdel Irada: @<memethecat>: You're right; I'm guilty of insufficient specificity. To be accurate, I should have explicitly referred to 26. ...♕b6+ *followed by*
27. ...♕d8. I had thought that apparent by inference, but I should know better than to make such an assumption. Good catch. |
|
| May-04-12 | | erniecohen: <<rilkefan>: <<erniecohen>: Sigh, another cooked problem.>
With stockfish I'm getting 2.5 for the game line at a depth of 29, 2.3 for Rd6 at a depth of 29.> Are you using the gameline with 27...♕d8? There's no way you can judge that as 2.5. |
|
| May-04-12 | | King Death: < erniecohen: Are you using the gameline with 27...Qd8? There's no way you can judge that as 2.5.> Who cares if it's +2.5 or +12 or -600 according to some engine? This ending after 28.Re7 Qd7 29.Rd7 is obviously much better for White if not clearly winning and it's all that matters if you're as strong as you claim to be. It helps to move the pieces around some and figure out what's going on instead of plugging every position into an engine. |
|
| May-04-12 | | erniecohen: <King Death> My claim was that 25. ♖d6 is stronger than 25. ♖d7. <rilkefan> claimed that 25. ♖d7 is leading to a better Stockfish evaluation. Here are the two positions (each with Black to play): after ♖d6 -

and after ♖d7 -

Are you telling me that you think that the second position is better for White than the first, even though the first he has a ♖ instead of a ♗? If not, what's you're problem? My guess was that <rilkefan> had taken his evaluation at the end of the game, after Black had misdefended. |
|
| May-05-12 | | Patriot: I figured 25.Rd7 Bxd7 26.Qxd7 Re8 27.Rxe7 Rxe7 28.Qd8+ Re8 29.Be6+ Qxe6 30.Qxe6+ . I didn't even consider 26...Qb6+. |
|
| May-05-12 | | rilkefan: <Are you using the gameline with 27...Qd8? There's no way you can judge that as 2.5.> Take it up with stockfish, it's a bit stronger than I am. You can see my inferred reasoning for the strength of white's position in the ...Qd8 line above. |
|
| May-05-12 | | TheBish: <Patriot> Exactly the same for me! Missed 26...Qb6+, but saw the winning sequence. Except that I had 29. Bd6+, not 29. Be6+ (which isn't possible). |

| Jan-24-14 | | dusk: <Memethecat> 27... Qd8 28. Rxe7 Qxe8 29. Bd6 |
