| Posted by taoistlunatic ability-tw.com 7/13/2002 13:14:30 |  Subject: IQP in queen's gambitMessage: Why does white willingly accept an isolated queen's pawn on black's open file, in many opening variations of the queen's gambit? I can't figure out why white doesn't avoid it. For example here in the Queen's gambit declined, semi-tarrasch defense 1.d4 d5 2.c4 e6 3.Nc3 Nf6 4.Nf3 c5 5.cxd5 Nxd5 6.e3 Nc6 7.Bc4 cxd4 8.exd4 or another variation of the same opening 7.Bd3 cxd4 8.exd4 This is just one example of theoretical opening lines which accept an IQP on the enemy's open file. Is the pawn offering some dynamic control of the board? Or is it difficult to attack? Is white just avoiding something even worse positionally? |
| Posted by philaretus ability-tw.com 7/13/2002 15:39:24 | taoistlunatic Message: White accepts the isolated pawn because he can avoid it only by inferior lines of play. His principal compensation is fairly obvious: Black has still not freed his position. In order to do that Black will have to play e5 in due course, dissolving White's isolated pawn. Meanwhile, White enjoys free play with his pieces. |
| Posted by taoistlunatic ability-tw.com 7/13/2002 16:11:57 | thanks philaretus. Message: I basicaly thought so, but why are the other lines of play inferior? I guess they allow black to free his position, nevermind, answered my own question... :) |
| Posted by atrifix ability-tw.com 7/13/2002 16:54:10 | The IQP Message: is a static weakness, but it is also a dynamic strength. Simply having an IQP is not necessarily a weakness, and in many cases it leads to a kingside attack supported by an outpost on e5 or similar themes. At any rate, in modern practice it is perfectly acceptable to assume an IQP, depending upon the position. |
| Posted by zdrak ability-tw.com 7/13/2002 23:01:02 | here's an example Message: How the outpost at e5 can play a part in a white kingside attack. Note that black never got the chance to attack the isolated d4 pawn. This one comes from a classic game Botvinnik-Vidmar, 1936 1. c4 e6 2. Nf3 d5 3. d4 Nf6 4. Bg5 Be7 5. Nc3 O-O 6. e3 Nbd7 7. Bd3 c5 8. O-O cxd4 9. exd4 dxc4 10. Bxc4 Nb6 11. Bb3 Bd7 12. Qd3 Nbd5 13. Ne5 Bc6 14. Rad1 Nb4 15. Qh3 Bd5 16. Nxd5 Nbxd5 17. f4 Rc8 18. f5 exf5 19. Rxf5 Qd6 20. Nxf7 Rxf7 21. Bxf6 Bxf6 22. Rxd5 Qc6 23. Rd6 Qe8 24. Rd7 black resigned Of course this one example shouldn't drive you to the other extreme and convince you that "all IQP positions are good for white" - but rather show you the dinamic chances white gets in return for the static weakness. |
Chess news: Back to the drawing board -- Peter Leko rather predictably took no risks with the white pieces and secured chess tournament victory at Dortmund by steering play into a known drawing variation in the Marshall Attack to the Ruy Lopez. Of course Leko needed the cooperation of his opponent, Dortmunder Arkady Naiditsch but Naiditsch probably felt he had already given his home crowd enough entertainment by defeating former world chess champion Vladimir Kramnik in round three. Leko finished clear first, undefeated on 4.5/7, half a point ahead of the field. Kramnik had a terrible chess event and finished on a negative score after losing a middlegame battle against Vasily Ivanchuk. The position was roughly ... Victory for Karjakin -- Nigel Short was 5.5-2.5 behind at the end of the fourth day’s play in his ten game Rapid Chess match against the Ukrainian chess prodigy Sergei Karjakin. Karjakin secured victory with a day to spare outplaying Short in the seventh game before Short unleashed the King’s Gambit and won the eighth. The exhibition chess match was staged at the Kiev Puppet Theatre and sponsored by the Ukrainian mobile operator life :) Short lost the first three and he might have been a bit punch drunk but he hit back in style. Game 4 was a bit Punch and Judy, Nigel was Punch. N Short – S Karjakin; Rapid Match (4) Kiev; Closed Sicilian; 1.e4 c5 2.Nc3 d6 3.Nge2 Nf6 4.f4!? (Short naturally wanted to avoid ... Negi shows potential -- The Indian chess prodigy Parimargan Negi,15, was one of the winning quartet of GMs at the big money World Open just concluded at the Sheraton Hotel in Philadelphia. Negi warmed up by winning a smaller chess event in Philadelphia and continued his good run to score 7/9 and share first with Evgeny Najer of Russia, Ljubomir Ftacnik of Slovakia and Alexander Moiseenko of Ukraine. In the absence of Gata Kamsky and Hikaru Nakamura the American chess challenge was eclipsed. Najer won a blitz tie break against Negi to win the title but the $55,000 for first to fourth place was shared. Overall, chess event organiser Bill Goichberg handed out $320,000 in prize money among ... | |
