In a recent game I had the opportunity to force my opponent to lose his queen in exchange for my two rooks, I didn't in the end as there was no obvious strong attack to follow up with. Any thoughts?

Posted by drtimer ajaxwrite.com 11/19/2007 08:37:49 Play online chess	Thanks ganstaman Message: interesting reading ——— Chess: Working the variations — Is there any way through Black's solid defence? How can he increase the pressure on Black's position? RB: If only my rooks were doubled on the e-file maybe I could put pressure on the knight on e7, but in the time it would take to get my heavy pieces lined up, Black would be able to deal with any threat – 1 Re2 Ng6 2 Rae1 Rxe2 3 Qxe2. I'm left in control of the e-file but how does that look? Not too bad, I suppose, but also not very exciting. Is there something better? I can't see any tactics, so maybe the thing to do is to try to take advantage of the weak dark squares on Black's queenside. If I could put my knight on c5 and my queen on d4, I'd be a very happy bunny. Trouble is, I don't ...
Posted by ionadowman ajaxwrite.com 11/22/2007 19:57:47 Play online chess	The value of queen versus 2 rooks ... Message: ... depends very much on position. Generally, though, I've found that the situation is at the outset hard to judge. In a pure Q plus pawns vs 2R plus pawns, the queen needs the extra pawn for "equality". Maybe. Here's a game I played (as Black) several months ago that led to just such an ending. I've set the opening diagram several moves before the ending arrived, as the sequence is full of incident b Black had given up 2 pawns already - not altogether voluntarily - but has every piece aimed at White's king. 23...Qa3ch 24.Kb1 Bxb3!! 25.cxb3 Rxb3ch! 26.axb3 Qxb3ch 27.Kc1 Bxc3 ... Now, 28.Nxc3 Rxc3ch 29.Qxc3 Qxc3 leads to something not too dissimilar from the game continuation, but White has some shots of his own up his sleeve... 28.Rd8ch!! Kg7! 29.R4d4! Rc5! 30.R4d5 Rc4 31.Qxc3 Rxc3ch 32.Nxc3 Qxc3ch ... Now we have the 2R vs Q ending. How to assess? I thought Black had whatever winning chances were going, but couldn't believe they amounted to much... w 33.Kd1 a5 34.Rd2 a4 Just how do you stop the pawn?? 35.R8d3 Qb4 36.h3 a3 37.Ke2 Qe4ch 38.Re3!? Qc4ch 39.Kf3 a2 40.Rd1 Qc6ch! Beginning a remarkable zigzag manouevre to relocate the queen... White has little choice in his available options. 41.Kg3 Qc7ch! 42.Kf3 Qb7ch 43.Kg3 Qb8ch! 44.f4 ... At last White realises that the king cannot return to f3. 44...g4! 45.Rf3 gxf4ch 46.Kh2 ... The pawn is taboo: 46.Rxf4 Qb3ch picks up the d1-rook. 46...Qb2 47.Rff1 f3 It seems already clear that Black has all the play... 48.Rg1 Kh6 49.Kg3 fxg2 50.Rge1 Kh5 51.Rc1 f5 52.Red1 Kg5 53.h4ch Kh5 54.Ra1 Qb7! Of course, the a-pawn is still under the queen's protection: 55.Rxa2?? Qb3ch 55.Kh2 Kxh4 56.Rxa2 Qf3 57.R2d2 ... Just about the only defence against 57...Qh3ch. 57...Qf1! 58.Rxg2 Qxd1 ... and Black won (59.Rf2 Qg4 60.Rg2 Qxg2 61.Kxg2 Kg4 0-1). The win proved surprisingly easy for Black. If White can save the game, it must be by adopting a different course of action early in the ending. Can he manouevre both rooks safely behind the a-pawn, say? Cheers, Ion ——— Chess: Tournament Life Isn’t Always Glamorous — Traveling is part of the life of a chess player. Sometimes the destination is glamorous — London or Gibraltar — but elite chess tournaments are often held in out-of-the-way places that do not top many tourist lists. The last four World Chess Cups have been held in the Siberian city of Khanty-Mansiysk, Russia. The Women’s World Chess Championship last month was in Tirana, Albania. And several top chess events have taken place in Elista, the capital of Kalmykia — a dusty Russian republic on the Caspian Sea. Sometimes the remoteness of the location is not the issue. In 2004, the World Chess Federation held its championship in Tripoli, Libya, and none of the Israeli qualifiers competed. The current ...

The rooks have to be connected all the time. Another big point seems to be the king's situation. Above, the black king is in a rather safe position, the white king is on open ground and easy to attack. ——— On Chess: Old veteran Kramnikstill showing spunk — At 36, Vladimir Kramnik is at a turning point that is problematic for many chess grandmasters. Faced with an onslaught of energetic younger chess players, the veteran competitors’ results often decline. And so it has been for Kramnik. Dissatisfied with his uninspiring performances of late, however, the former world chess champion seems to have ramped up his aggressiveness. Most recently, he finished first — ahead of several of the best chess players — in the world’s jewel of annual tournaments: the London Chess Classic in Britain. He did it professionally but conservatively by drawing with each of the top chess players — Viswanathan Anand, Levon Aronian, Magnus Carlsen and Hikaru Nakamura — while piling up wins against ...
