| Jan-19-09 | | UnsoundHero: Instead of 13...Nf6, black should try 13...f5, inviting white to win his pawn back, but slowing or stopping white's valiant K-side attack in the process. A possible continuation is 14 c5 Be7 15 Bxe4 fxe4 16 Qd4 d5 17 cxd6-ep Bxd6 with an active game. If then 18 Nb6 c5 19 Nxa8 cxd4 20 Nxc7 dxe3 with complications favoring black. Or 18 Qxe4 Rb8. |
|
| Jan-19-09 | | WhiteRook48: nice double bishop sac. I've heard of bishop sac on h7 before, but only recently of the second bishop sac on g7. |
|
| Jan-19-09 | | gmalino: In my opinion the combination could be done 1 move earlier with the same result, because the knight, if it would stand on d5, is useless there as well.
But maybe i miss something, i'm not a GM. |
|
| Jan-19-09 | | Confuse: If black plays 19. f5, is there still a quick win for white? I'm just curious... |
|
| Jan-19-09 | | cydmd: 19... f5 20.Qg6 Rf7 21.Bh6+ Kh1 22.Qxf7 and mate follows soon. |
|
| Jan-19-09 | | desiobu: After a very quick look ...Bc5+ -> ...Bd4 and black just might escape by a hair because white's mate has to come on dark squares. |
|
| Jan-19-09 | | mworld: games like this amaze me...whenever i get in a position like white's to strike that early it feels more like dumb luck in the opening getting me there rather than calculation and deflection of the enemy's attention. |
|
| Jan-19-09 | | Once: <gmalino> I thought so too, but Fritz shows that the Nd5 was doing something useful ... 16. Bxh7+ Kxh7 17. Qh5+ Kg8 18. Bxg7 Kxg7 19. Qg4+ Kh7 20. Rf3 Nxf4 21. Rxf4 f5

| Jan-19-09 | | ceebo: So what was black's best option at move 16?
I did some computer analysis and I think both Rb8 and Ra7 only lose to pretty cruel forks about 10 or 11 moves down the line. After 16.. Ra7 or Rb8, if White plays 17. Nxd5 then Black recaptures with the c-pawn. If White now tries the double bishop sacrifice as in the game then Black can prevent any immediate checkmates by playing Qc5+ and Qc2. Unfortunately he can't prevent his Rook from being forked a few moves later and so he loses too much material. The key move for White in both cases is the surprising f5! Two sample lines:
16. .. Ra7 17. Nxd5 cxd5 18. Bxh7+ Kxh7 19. Qh5+ Kg8 20. Bxg7 Kxg7 21. Qg4+ Kh8 22. Rf3 Qxc5+ 23. Kh1 Qc2 24. f5! (opening the Queen's path to d4)
Qxf5 25. Rxf5 exf5 26. Qd4+ Kg8 27. Qxa7
16. .. Rb8 17. Nxd5 cxd5 18. Bxh7+ Kxh7 19. Qh5+ Kg8 20. Bxg7 Kxg7 21. Qg4+ Kh8 22. Rf3 Qxc5+ 23. Kh1
Qc2 24. f5! (again but this time opening a path from g3 to b8!) Qxf5 25. Rxf5 exf5 26. Qh3+ Kg8 27. Qg3+ Kh8 28. Qxb8 On the other hand if Black plays 16... Bb7 then I think the same kind of idea: 17. Nxd5 cxd5 18. Bxh7+ Kxh7 19. Qh5+ Kg8 20. Bxg7 Kxg7 21. Qg4+ Kh8 22. Rf3 Qxc5+ 23. Kh1 Qc2 leads only to a draw. I can't see anything better for White after 16.. Bb7 than 17. Nxa8 Rxa8 where he is up the exchange for a pawn. |

f4 .Black seems to be doing fine here.>
Better than in the game, but not so fine:
22. Qh3+, 23. Qg3+ and 24. R moves checking, and W wins the Q. And due to the situation of Black Queen side 25. Kb6 wins another piece. |
|
| Jan-19-09 | | ceebo: <ricardolopez> my computer doesn't see much after 22.Qh3+ Kg6 23.Qg3+ Bg5 |
|
| Jan-19-09 | | itopcho: has anyone though of 22...Qd8 ?trying to force an exchange, after which black is left with 2 rooks, bishop and a knight against a queen and a rook, and that's not bad. I suppose I am missing sth here |
|
| Jan-19-09 | | mworld: 12.f4 was just brilliant by white - inviting Evgeni to take the e4 pawn and open up the b1-h7 diagonal! Black's only problem was falling for it and not taking a moment to think *why in the world would he give me this pawn?* |
|
| Jan-19-09 | | ricardolopez: <ceebo: <ricardolopez> my computer doesn't see much after 22.Qh3+ Kg6 23.Qg3+ Bg5 >
woow! that's true. I haven't seen that move. |
|
| Jan-19-09 | | Shubes82: what about 21...Qd8 |
|
| Jan-20-09 | | Confuse: <cydmd> thanks! |
|
| Jan-20-09 | | arsen387: <Once: Fritz shows that the Nd5 was doing something useful ...
16. Bxh7+ Kxh7 17. Qh5+ Kg8 18. Bxg7 Kxg7 19. Qg4+ Kh7 20. Rf3 Nxf4 21. Rxf4 f5
and Black seems to be doing fine here.> wow, that makes this game even greater. If 21..Qd8 than after exchanging R for Q+B and then taking the hanging N on b6, whites remain with Q+p vs R+B with enemie's K exposed, blacks have no chances |
|
| Jan-20-09 | | kevin86: It is a bargain to sac two bishops when you can put an entire enemy army to sleep. |
|
| Jan-21-09 | | tivrfoa: i love these sacrifices! just amazing. |

| May-31-11 | | ahmadov: This is a very good game indeed... I fully failed to follow the moves on the Guess the Move feature... |
|
| Oct-20-13 | | JimmyVermeer: Laszlo Polgar's book "Chess: 5334 Problems, Combinations, and Games" includes this game but Black's 5th and 6th moves are transposed, as are both players' 13th and 14th moves. |
|
| Oct-20-13 | | parisattack: Nice 2-B sac! Compare with the famous game Lasker vs J Bauer, 1889 where Black had a tad more resources to defend. Fine's Middlegame book has an excellent section on understanding the 2-B sac. |
|
| Apr-08-17 | | clement41: The structure arising after ...bxc6 is begging white to play c5; and white did a few moves later, hereby seizing the dark squares and fightung vs the ...d5 break.
This reminds me of

Then the double B-Sac, Lasker style, is a must |
