Jan-19-10		Marmot PFL: Nice win for white, in what looks like a trap still in the opening. Or did van wely plan this and just analyze badly? Bb7 on move 11 on 12 looks OK but maybe some Najdorf expert can comment better.

Jan-19-10		percyblakeney: <Or did van wely plan this and just analyze badly?> Good question, apparently 15. ... Bb7 was the novelty, and a few moves later he was totally lost. Something must have gone very wrong with his preparation.

Jan-19-10		HeMateMe: "look out!" Loek, not having a very good tournament, so far.

Jan-19-10		Eyal: <Or did van wely plan this and just analyze badly? Good question, apparently 15. ... Bb7 was the novelty> 15...Bb7 may actually be relatively better than 15...Rb6 that was played in 2 other games that appear in the databases (where Black just loses a piece - 16.Nxe7 Kxe7 17.fxe5 Nxe5 18.Rhe1 and if the knight retreats then 19.Nd5+) - but Black gets into a horrible position anyway after 13...Rxb4?; It's necessary to play first 13...h6, the point being that after 14.Bh4 Rxb4, 15.e5 dxe5 16.Nc6 fails to Rxf4. So h6 can also be played on move 12, of course, to prepare b4, and 12...Bb7 mentioned by <Marmot PFL> should also be ok. As it was, Van Wely indeed fell into what amounts to an opening trap. What a miserable performance (or preparation) by him - he lost like an amateur here.

Jan-19-10		Bradah: <As it was, Van Wely indeed fell into what amounts to an opening trap. What a miserable performance (or preparation) by him - he lost like an amateur here.> Not that bad, he just belong to Group B.

Jan-19-10		Jimfromprovidence: As bad as this game was for black, it would have been even worse after 24 Qc8+ Ke7 25 Rd7+ Nxd7. click for larger view

Jan-20-10		M.D. Wilson: Loek out!

Jan-22-10		chancho: He ran out of Loek.

Feb-01-10		notyetagm: http://www.chessvibes.com/reports/c... <16:15 CET As expected, Van Wely quickly lost against Ivanchuk. There was some amazement in the press room when Ivanchuk didn’t go for 24.Qc8+ and 25.Rd7+, winning the queen (as also pointed out in the comments), but in fact the line he played wins even quicker.> Firebird thinks 24 ♕a6-c8+ is slightly stronger than Ivanchuk's 24 ♕a6-a8+ idea. 1: Vassily Ivanchuk - Loek Van Wely, Corus Wijk aan Zee NED 2010 click for larger view Analysis by FireBird 1.0 beta w32: 1.

Feb-02-10		notyetagm: Wow! I should have known better: after a longer thought Firebird agrees with Ivanchuk, that 24 ♕a6-a8+ is stronger than 24 ♕a6-c8+. 24 ♕a6-c8+ is just more obvious. 1: Vassily Ivanchuk - Loek Van Wely, Corus Wijk aan Zee NED 2010 click for larger view Analysis by FireBird 1.0 beta w32: 1.
