| Jul-25-09 | | cannibal: e6? was really a nasty blunder. Much worse than the one against Caruana where the complications were just too much to see through. Here he just failed to see a quick forced line. Maybe he can still draw now, but it must be a bit of a psychological blow. |
|
| Jul-25-09 | | YouRang: Moro might have been thinking 43...e6 44.dxe6 Rxd3 [diagram] wins a rook, but it allows 45.Qc8+!, and then 45...Kg7 46.e7!; or 45...Kh7 46.exf7! winning either way.

| Jul-25-09 | | szachista: I can't believe that players of the world top can make such big blunders in long games with over 40 minutes on the clock. Although I'm rated below 1900, I knew that 43. ... e6 is a wrong move... Morozevich didn't. |

 | | Peligroso Patzer: <szachista: *** Although I'm rated below 1900, I knew that 43. ... e6 is a wrong move... ***> The tactics after 43. ... e6 44. dxe6! are quite tricky. I am surprised that Morozevich failed to analyze them correctly, but any <1900 player who "knows" that 43. ... e6 is a blunder is probably running an engine. |

I just saw that white can play 45. e7 and that's all. |
|
Jul-25-09
| | Peligroso Patzer: <szachista> But the e7 idea does not work in all lines. After 44...Rxd3 45.Qc8+ Kh7 White’s winning move is 46.exf7 (46.e7? Rb3–+). The specific tactics are quite tricky and any human, even a super-GM, can go wrong trying to work through them OTB. |
|
| Jul-25-09 | | unsound: That 46.exf7 line is an aesthetically pleasing one. Can't say I saw all that--but even that line is a similar idea to the e7 lines, so I join <PP> in being surprised that Moro went wrong. |
|
| Jul-25-09 | | YouRang: Geez, 49...Kxf6 is another blunder by Moro, and this one should cost him the game... |
|
| Jul-25-09 | | cannibal: <Peligroso Patzer>
Why 45.Qc8+ first? I mean its maybe really the better move, but 45. e7 instead is really the move an amateur player sees, so unless there's something seriously wrong with that one, I assume Moro simply had a blackout. |
|
| Jul-25-09 | | YouRang: Now, 50.Qd8 pins the rook, and 50...Kf7 is met by 51.Rf3 Bf6 52.Qd5+! Kg7 [diagram]

Then 53.Rxf6! Kxf6 54.Bg5+ Kg7 55.Bxe7  |
|
| Jul-25-09 | | YouRang: <cannibal> It looks like your 45.e7 wins too -- 45.Qc8+ perhaps a bit faster. :-) |

Qc8+ was correct based on computer analysis posted by <YouRang>. 45. e7 probably also wins, but it's somewhat less clear, for example: 45.e7 Bc7 46.Qxc7 Qe4 and Black threatens a nasty discovered check. The main point in all of this, I think, is that the tactics are really tricky. Most days, Morozevich would work them out correctly, but they are sufficiently dificult that today (apparently an off-day for him), even he went astray in the complications. |

| Jul-25-09 | | Slaven MNE: It looks like we are going to have sole leader and it will be... Ivanchuk!!! |
|
| Jul-25-09 | | YouRang: Yep, game over Moro lost. Pity, he was better for most of the game. |
|
| Jul-25-09 | | znsprdx: well thatz what you get for playing 12 move draws Caissa's payback |

| | Peligroso Patzer: <Slaven MNE: It looks like we are going to have sole leader and it will be... Ivanchuk!!!> After six rounds, and with the second and final rest day coming up tomorrow (Sunday), the standings are very tight: Ivanchuk is +1, Gelfand is -1, and the other four are on 50%. |

My main point is, this e7-line can't possibly be good for black, so I'm having some serious doubts if Moro simply got lost in some tactical details there. I mean even if the actual win for white may be a bit tricky (with that 46. ...Qe4or so), its pretty clear that black can't possibly hope for more than a narrow escape (e.g. by repetition) there, and that can't be what Moro had in mind with his strong position a while before.
So i still find it more likely that he simply had a blackout that cost him a pawn. |
|
| Jul-25-09 | | calpawn: For a player of Moro's caliber the rather large blunders (two in this game) raise questions. I'm not buying that the variations were too complicated or that anyone could make these blunders. He's now had three pretty big blunders in the tourney so far. I think he's losing some concentration at critical moments. Too bad because I'd love to see him produce some masterpieces. |
|
| Jul-25-09 | | kellmano: I too am worried about Moro. Let's focus on the win against Alekseev in round one. He also benefitted from a blunder vs Gelf in round two. |
|
| Jul-25-09 | | YouRang: Just for laughs: Had Moro played 44...Rxd3, the line might have ended with a cute stalemate trap: 45.Qc8 Kh7 46.exf7 Rd8 47.Qxd8 Qe4 48.Ka1 Bxb2 49.Bxb2 Qe1 50.Ka2 Qe6 51.Kb1 Qf5 52.Kc1 Qc5 53.Kd1 Qg1 54.Kc2 Qf2 55.Qd2 a4! [diagram]

Note that 56.Qxf2? is stalemate, and 56.f8=Q Qxd2+! Kxd2 is stalemate. White's best move is 56.f8=N+! :-) |

| | Peligroso Patzer: After Alekseev's stunning win today, I find it interesting to reflect how he won the tournament last year: 41st Biel International Chess Festival (2008) with an all-decisive second half. After going +2 in the first half in 2008, Alekseev actually lost to Bacrot in round 6, but then got into a playoff (which he won against Dominguez) with 3 wins and 1 loss in the final four rounds. Alekseev's equal first in the final regular standings was thanks in no small part to Bacrot's defeat of Dominguez in the last round when the tournament standings after 9 rounds had put the latter in strategic position to play for a draw. |

| Jul-25-09 | | whiteshark: <YouRang: <Geez, 49...Kxf6 is another blunder by Moro, and this one should cost him the game...>> It did. |
|
| Jul-26-09 | | anandrulez: Moro needs to work on his "win by all means" attitude . He has had success using the same formula but if u look at guys like Carlsen Radja - the new brigade - they all risk less . |
|
| Jul-26-09 | | percyblakeney: <Moro needs to work on his "win by all means" attitude> He did create winning chances with black against both Caruana and Alekseev, and a "normal" Biel Moro might have scored at least +1 instead of -2 in these games. Of course it's also normal to blunder now and then but doing it in this way in two black games in a row is unusual also for an uneven player like Moro. <After Alekseev's stunning win today, I find it interesting to reflect how he won the tournament last year> He hasn't seemed to be too ambitious this year though, taking draws in positions where it looked as if he could play on, and then being pressed hard with white against Morozevich. As even as it is he can definitely repeat his victory though. |

 | | tamar: Following Moro's games with computer, I can't help but wonder if his woes are greater now because of the general rise of technique occasioned by training with computers. I'm not suggesting anyone is cheating. But Caruana's patient positioning of his pieces in a passive position was mirrored by Alekseev's calmness in the face of disadvantage by playing a3 and Ka2. In both cases, Moro's errors happened when he was to shake a small advantage into a major one, and was met by a precise sequence. |
