What principles are involved here? You might recall that in the opening game of his defence of the World Title, Capablanca moved the wrong rook, and eventually lost the game, so the decision isn't always easy. However, that particular topic might be better discussed in another thread (but I am aware of wschmidt's point in mentioning it here). To return to the central question, let's take a simple example. In the following diagram, White might decide that it would be a good idea to induce the exchange of knights on d5: w Suppose play goes 1.Nd5 Nxd5. How ought White recapture (2.exd5 or 2.Rxd5)? Well, 2.exd5 does establish a Q-side pawn majority for White, and Black's bishop doesn't look very happy, but Black has now a K-side majority that might become more active than White's on the other wing; and, even more significantly (I feel) Black backward d3-pawn has now been masked from any frontal attack down the d-file. After 2.Rxd5, White will soon double rooks on the file, and can start thinking about conducting a general advance of the Q-side pawns, and/or manouevring his bishop to where it will bring added pressure on Black's d6. Indeed, there is something to be said for moving the bishop before doubling the rooks, e.g. if Black moves a rook to d8 as his second move, say 2...Rfd8 3.Bb6 Rd7 4.Rad1 Rac8 5.c3 or 5.Bc5!?). Suffice to say that the rook recapture seems to offer a more concrete subsequent target for White to aim at, whilst depriving Black of much counterplay beyond some ineffectual swiping down the c-file. The piece recapture on d5 is much more often preferable to a pawn recapture if it means Black is going to be left with a backward pawn on an open file. Just one example among many one might have suggested... Cheers, Ion |

Chess news: Vietnamese surprise in Moscow -- The Aeroflot Open, arguably the strongest open chess tournament ever, ended Feb. 19 in Moscow. The field of 80 included 75 chess grandmasters. The surprising winner of 21,000 Euros (about $28,000) for first place was 18-year-old Le Quang Liem of Vietnam, who scored an undefeated 7-2. His success followed his tie for first place in the Moscow Open, another GM-heavy chess tournament, a day before the start of the Aeroflot Open. Entering the last round of the Aeroflot Open, Le shared the lead with his countryman Nguyen Ngoc Truong Son, 19. Le defeated 2009 winner Ian Nepomniachtchi (Russia), while Nguyen lost to GM Anton Korobov (Ukraine), who took ... The f-pawn, part 3: a blunt but effective attack? -- Punting the f-pawn down the chess board may be desperate but it sometimes gets results. The Grand Prix Attack. White has just offered the f-pawn. How should Black reply? RB We've been using the metaphor of route-one football in our survey of the f-pawn advance, and while we all know from experience that the long, hopeful punt down the park can produce the occasional goal, this looks to me just a little too early and a little too crude. The team is barely on the pitch and the ball has already been booted up the other end. On principle alone it seems wrong. I can't decide whether Black's best response is 1…exf5 or simply to continue with ... Chess notes -- In a review of Diego Rasskin-Gutman’s book “Chess Metaphors’’ (MIT Press), which deserves special attention by chess lovers, former world chess champion Garry Kasparov has published in The New York Review of Books a retrospective look at the development of chess machines. He also expresses a hope for the future. It is strange to this column that Kasparov ever thought that he would be a worthy opponent of chess computers. The computers have so many advantages over human beings in playing chess that it is hardly a fair fight. The chess computer memory is simply a copying device, the machine can look at any number of books on chess openings, and ... | |
