| Feb-18-07 | | Aspirador: <Chesspro.ru was suggesting 19. Rxa4 Qxa4 20. g5 and black would be uncomfortable:> in this case, black would have had to play 20...Qb5 or 20...Qa5 which is still playable for black. The black queen covers the fifth rank. |
|
| Feb-18-07 | | amuralid: <iron maiden: 25. Bd5 Qe7> Then 26. Qg6. The f7 pawn is pinned. |
|
| Feb-19-07 | | Confuse: hmmm I guess thats not as crazy. I admit I was surprised to hear a GM spending near 2 hours of thinking time for 12 moves : ) thanks for clearing that up! |
|
| Feb-19-07 | | karlc1980: A winning line instead of 22. Qxf6 was 22. Be4! f5 23. Bxc6 bxc6 24. g5! with the threat of g6. Now the only move is 24. ... Qc5 (24. ... Qd5 25. g6 fxg6 26. Qxg6+ Kh8 27. Qh6+ Kg8 28.Re7+  ) 25. g6 fxg6 26. Qxg6+ Kh8 27. Qh5 Kg7 28. Re3! Rf6 (after other moves black will lose his queen, resulting in a hopeless ending, or gets mated) 29. Rg3+ Kf8 30. Qh8 Ke7 31. Qxc8 Qd6 (only move that defends c7 pawn) 32. Rg7+ Rf7 33. Rxf7 Kxf7 34. Qxf5 White will probably win this queen's ending having two passed pawns. |
|
| Feb-20-07 | | karlc1980: Funny enough Leko must have spotted this line during the game, because he's pointing it out to Ivanchuk in the picture of the post mortem analysis on chessbase. They have the position after 24.g5 in the last line.

Qh6+ Kg8 28.Re7+ ) 25. g6 fxg6 26. Qxg6+ Kh8 27. Qh5 Kg7 28. Re3! Rf6 (after other moves black will lose his queen, resulting in a hopeless ending, or gets mated) 29. Rg3+ Kf8 30. Qh8 Ke7 31. Qxc8 Qd6 (only move that defends c7 pawn) 32. Rg7+ Rf7 33. Rxf7 Kxf7 34. Qxf5 White will probably win this queen's ending having two passed pawns.> Good computer analysis. But even for Ivanchuk, it would have been difficult to calculate on the board what happens after the forced variation 22.Be4 f5 23.Bxc6 bxc6 24.g5 Qc5 25.g6 fxg6 26.Qxg6+ Kh8 27.Qh5+ Kg7 28.Re3. This shows that 16...h6? was bad, although it was very difficult to foresee White's kingside attack on the board. It appears that Leko did not like 16...Be6 17.Ng5, but it was better than the too slow 16...h6. |

| Feb-21-07 | | Fisheremon: <percyblakeney: Chesspro.ru was suggesting 19. Rxa4 Qxa4 20. g5 and black would be uncomfortable: Here 20. ... hxg5 loses quickly after 21. Qxg5 (for example 21. ... f6 22. Qd5+ Kh7 23. Qh5+ Kg8 24. Ng5 with mate to follow. Also 20. ... h5 would have run into trouble after 21. Nf6+ where 21. ... gxf6 loses soon because of 22. gxf6 followed by Qh6.> 20...h5 21.Nf6+ Kh8 22.Qe2 (and a bit long, but forced combo). The main line here's: 20...Qa5 Try to find again a long, but not so obvious combo. |

Qh8 Ke7 31. Qxc8 Qd6 (only move that defends c7 pawn) 32. Rg7+ Rf7 33. Rxf7 Kxf7 34. Qxf5 White will probably win this queen's ending having two passed pawns.> 32.Re3+ with an easy pawns ending for White. |
|
| Feb-21-07 | | Fisheremon: It's interesting to note that even on 24 move White missed 24.Bh7+ with the main line: 24...Kxh7 25.Re5 Nc6 26.Qh4+ Kg6 27.Qh5+ Kg7 28.Rg5+ Kf6 29.Rxc5 bxc5 30.f4 with winning attack. |
|
| Feb-22-07 | | kbaumen: I really liked white's a4, wtih the idea of Nf6, and if black doesn't take the knight, then Qc2 winds, if he does, then black has an attack. |
|
| Feb-22-07 | | notyetagm: From chessninja.com/dailydirt:
<ChessBase has some nice photos and is running regular analysis from GM Marin. He's under time pressure but consistently churns out great stuff. To nitpick, his report on round one misses that Ivanchuk still had a forced win over Leko, not just a perpetual. Kasparov pointed out 22.Be4!, which wins very nicely after 22..f5 23.Bxc6! bxc6 24.g5. Chessvibes has a few cool post-mortem videos.> |

I was wondering how 22 ♗e4! f5 23 ♗xc6 bxc6 24 g5! was winning. |

Like you said, the point is that if Black does not capture the White f6-knight by playing 19 ... ♔h8, then the <DOUBLE ATTACK> 20 ♕c2 wins material. (VAR) Position after 19 ... ♔h8 20 ♕c2:

| Feb-25-07 | | clocked: <Fisheremon> I don't know if it is fair to say he missed Bh7+ as they discussed this line in the post mortem along with almost every other conceivable idea. The one computer contradiction was their discussion on the line 25.Bd5 Kh7 26.Bxf7 where Chucky insists on Ne5, Leko insists on Nh8, and the progs insist on Nf4!. For example Ne5 Rd5 Rxf7 Qh4+ looks Kg8 looks like it fails because RxQ loses to the royal fork, but Qg5+ Rg7 Qxe5 Qf8 Qd4 Re7 Rg5+ Rg7 RxR QxR Qd8+ Qf8 QxQ KxQ with 3 passed pawns against a bishop. And Nh8 Rd5 Rxf7 Qh4+ Kg7 Rxc5 bxc5 Qd8 |

But in the progs line 26...Nf4! seemingly a draw.
My line with 24.Bh7+ quite forced to the one similar to Peter's. |

| Feb-27-07 | | Hesam7: chesspro's recommendation looks interesting: 19.Rxa4 Qxa4 20.g5 Qb5 [ Toga's suggestion but what else? <percyblakeney> points out that 20...hxg5 & 20...f6 both lose. Also 20...Rfd8 is met by 21.Qf4! ] 21.gxh6:

21...Rd8 22.Qf4 Qe5 23.Qh4 Bf5 24.f4 Qe7 25.Qxe7 Nxe7 26.Nf6 gxf6 27.Rxe7 Rd1 28.Kh2 Rd7 29.Rxd7 Bxd7 30.Bxb7 Kh7 31.Be4 Kxh6 32.Kg3 f5 33.Bd5 Kg6 (eval: +0.83) |

You should also consider variation with 21...Qh5. |
|
| Feb-28-07 | | Hesam7: <<Fischeremon>: You should also consider variation with 21...Qh5.> I think Black is lost after: 19.Rxa4 Qxa4 20.g5 Qb5 21.gxh6 Qh5?! 22.hxg7 Kxg7 23.Re3!

My variation with attack on both sides is: 25.Qe3 f6 26.c4 Ne5 27.c5 Rd8 28.cxb6 cxb6 29.Qb3 now Queen-side pawns collapse, but still with strong pressure on King-side. The feature of the position is that Black's Bishop is more important defender than his Knight. |
