| Camus: what about 19.f4 Nc6 20.Nxf7 ? For example: 20. ... Kxf7 21.Bc4+ ...
a)21. ...Re6 22.f5
b)21. ...Ke7 22.Qd6#
c)21. ...Kf6 22.Bg5#
d)21. ...Kf8 22.Qd5 Qf6 23.Bg5...
Is there something I missed? |

| euripides: <Camus> It looks good. Black may be able to reject the sacrifice with 20...Qe7 21 Bc4 Kf8, when material is equal and White looks much better though I don't see a forced win. I'm not sure if Black could contemplate 20...Kxf7 21 Bc4+ Re6 22 f5 Nde5 giving the rook back. |

| Cyphelium: <Camus> You are trying to play the bishop on e3 right through the pawn on f4 in both c) and d). In c), white can play 22. Qc3+ winning instead. However, line d) seems critical. 23. e5 looks strong, but then 23.- Ne7! is a bit tricky: 24. exf6 Nxd5 25. fxg7+ Kxg7 and black still is a piece up, even if white might have some compensation. 24. Qxd7 Qc6! seems to hold too. |

| greystar69: There are a lot of combinations here. Just one question though - is this game totally lost for white? I would've thought with a bishop pair on an open board like this, plus the extra pawn, there would still be enough counterplay to making fighting on for a draw worthwhile. |
|
| Jan-19-05 |
| child of my tears: <greystar69> After 25Rd8 black must lose one of the bishop pair without compensation to either Rxd7 or Ne2+. So this tactic is called an interference eh? Nigel Short used something similair in his game vs Morozevitch at Corus yesterday, but the interference threatened mate rather than winning material. |
|
| Jan-19-05 |
| DexterGordon: <greystar69>, I think the problem is that after 25...Rd8, White is going to lose one of his bishops! |

| noone2: White is winning after the simple 19 N:e8. There is no reason to be critical of white's play to this point. White simply overlooks the tactical shot that ended the game After 19 N:e8 Q:e8 20 f4 Nc6 21 e5 white is up material, fully developed and has a large space advantage. Black's position is very cramped and before untangling the queenside black will certainly lose more material. |

| JustAFish: I think 21 ... Nxd4 wins as well.
21 ... Nxd4
22 Rxd4 Bxd4
22 Qxd4 Qxd4
23 Bxd4 Rxc1+
... and black has two rooks versus white's two bishops... |

| jkiipli: <Fresh> You dont like this and that makes no point, as you can see, white did not give away material, but instead ended up 1 pawn more at move 21, the tactical oversigth of the 21...Bd4 is quite forgiveable.
In the contarty, I liked how white played, I wish I could play this kind of sacs, chess is not for cowards |

| euripides: <justafish> after 21...Nxd4 White has 22 Qxd8 Nxe2+ 23 Kf2 Rexd8 24 Kxe2 (and other similar lines). This idea doesn't work after 21...Bxd4 because Black then plays 22...Bxe3+ and the bishop will not be attacked by the white king. |
|
| Jan-19-05 |
| jkiipli: <JustAFish> what do you do after 22Qxd8? |
|
| Jan-19-05 |
| JustAFish: <jkiipli> and <euripides> Yes, I suppse that after this line the best white can do is a dead even position. I neglected the fact that after the king moves from check on after 22 ... Nxe2 +, it will then be able to snatch up the Knight after the queen is removed. This is why I'm still a lowly d-class player... |
|

| Shubes82: JustaFish, I saw that line, interposing the knight on the D file instead of the bishop. i think it works just as well and is just as decisive. |
|
| Jan-19-05 |
| kbob4435: How about White bringing a bishop to the attack, such as 20. Ba6? This undermines the knight and threatens the pawn on b7, followed by attacks on the N on c6 and thereafter, the B.
If 21. ... bxB, then RxN eyeing the bishop next to undermine the other N.
If White moves his N on d7, then N simply takes R. |

| Rubinstein: and 23 Qxe8 would succumb to
23 ... Nxe2+
24 Kf2 Red8
25 Rc8 Rc8
26 Ke2 Rc2+
27 Bd2 Rb2
28 a4 b6 |

| midknightblue: This is a simple yet very nice combination. Wish i could say I got it right, but actually I came nowhere near getting it because it seemed like there were way to many possible different piece captures to figure out the line. I considered something involving 22...Bd4, but for some reason just couldnt reason through it. Mostly, I assumed that white could trade queens with 23 Qxd8 and end all the threats, but now it is clear that black has the critical "in between move" of 23... Bxe3 that would win a free bishop. |

| Dr Gogusetti: Am not getting full score of the game on my computer. Please correct this. |

| kevin86: A great problematic solution! The odd looking sac kills white's communication and costs white material. |

| maxundmoritz: 23.Bb5 loses the Knight, but what about 23.Qxd8 for White. For example: 23... Rxc1 24.Bxc1 Nxe2+ 25. Kf2 Rxd8 26. Kxe2. Is that enough for Black to win? |
|
| Jan-19-05 |
| maxundmoritz: <patzer2> Do you see this game as won? After 23.Qxd8 and the line from above, does Black have enough material advantage (R vs. B and pawn) to force a win? Or does White have legitimate hope for a draw? |
|

 |
| patzer2: The solution to today's puzzle is the beautiful obstruction or interference move 21...Bd4!, forcing the win of the exchange with an endgame advantage. However, after the best defense with <23.Qxd8 Rxc1 24.Bxc1 Nxe2+ 25. Kf2 Rxd8 26. Kxe2> , pointed out by <Maxundmoritz>, White, with an extra pawn and an active Bishop for the exchange, has excellent practical drawing chances. |

| who: I think that 15 Nbd5 was brilliant and leads directly to 18. NxR QxN where white has a rook and two pawns for two pieces. if 19. f4 Nc6 (Ned7 leads to trouble after c5 Na4 e5 threatening b3 and Bb5.) 20. e5 leaves white up a pawn and after placing his bishop on f3 can attempt to push his queenside pawns the game certainly even if not in white's favor. i think white got a bit greedy with 18.c5 with the idea of winning back the knight, he simply missed the tactical reply 21...Bd4! otherwise his game play was not only sound but really impressive. On a seperate note i think that white invisioned 17...Re7 with strong attacking possibilities i'm not sure what follows after that but c5 Bg5 and NxB all look very strong. |

|
| who: Whites best chances after 21. Bd4 lie with 23 Qxd8 Rexd8 24 Kxe2 leaving white with a RBP v RR endgame |
|
Jan-21-05
|
| euripides: <who> After 23 Qxd8, 23...Rxc1+ as patzer and max suggest above looks better, as drawing chances are usually reduced by the exchange of rooks. |

| hesyrett: 19 c6? blew it. What's the rush? After 19 f4  c6 20 b4 White has two  s and a bind for his piece, plus numerous threats, e.g. 21 b5 followed by 22 c6, or 21  c4 followed by 22 a3 and 23  a2. Under no circumstances should White swap his monster on d6 for Black's passive  or . |
