Posted by nathanman22 www6conf.org 4/18/2008 15:30:45 Play online chess	Subject: General Rules and Guidelines for Multiple Takes... Message: Okay, so you are in a position where you have two possible pieces that can make an exchange, and you don't know which piece to take with. The result will not be a higher loss (for instance, you don't take with a queen to get a pawn or something like that), but will result in either a final placement (last exchange) or a equal exchange. What piece should you take with? What are some guidelines and rules to help guide those of us who struggle with knowing what is the best capture? I'm looking for some guiding principles and ideas behind captures involving multiple possibilities, in general. Any assistance is welcome! Thanks. -Nathan
Posted by wschmidt www6conf.org 4/18/2008 15:55:04 Play online chess	I think the question is so general Message: that any answer is hardly going to be helpful. Without knowing something about the position on the board you''re pretty much left with banalities like, "Capture with the piece that results in the maximum activity for all your pieces" or "If possible, capture with the piece that is more poorly placed than the other" or, Capture with the piece that will make the most sense on that square". Or some such. * Unfortunately, this is a bit like the grandmaster advice I remember reading awhile back about which rook to move to the open file: take as much time as you possibly can analyzing which rook you think should go to the open file - then move the other one.

Posted by ionadowman www6conf.org 4/18/2008 18:55:42 Play online chess	nathanman22... Message: ... I think wschmidt has a point, and maybe the way to tackle this (and get the most benefit from this thread) is to bring in some examples from past play. Did you have such a situation in a past game in which you felt that you had made just such a mistaken decision? wschmidt does raise a related point about choosing which rook to occupy an open file. 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: Blazing Baden-Baden -- Michael Adams turned out for Baden-Baden in the German Bundesliga at the weekend and scored 1.5/2. His team lead the chess competition after nine of the 15 rounds with a perfect score. Baden-Baden even achieved a rare whitewash and defeated Berlin 1903 8-0. Baden-Baden’s strength is illustrated by the fact that Adams plays on board 3. Luke McShane’s Werder Bremen are in joint second place having dropped two match points. One of those was to the bottom club Erfurter SK who were out-rated by an average of over 180 points per board but managed a 4-4 draw. McShane played on chess board ... Gibraltar win puts Michael Adams back on top of the British pack -- Last autumn Michael Adams lost the England No1 chess spot for the first time for a decade when his below-par results coincided with Nigel Short's purple patch. Adams used to be a world top-10 chess grandmaster but his poor run also dropped his international rating below the elite GM 2700 mark. This double reverse stung the 38-year-old Cornishman into adding a more incisive touch to his strategic game and last week he triumphed at the competitive Gibtelecom Open while Short struggled against the super-GMs at Corus Wijk. The outcome is that the live daily chess ratings today show Adams back above 2700 and Short below it. The old order is restored and, since ... Chess Grand Prix to end in May -- The World Chess Federation (FIDE) has announced that the final Grand Prix tournament will begin May 5 in Astrakhan, Russia. The six-tournament series was supposed to conclude in 2009, but three of the six cities that promised to host tournaments backed out. FIDE deserves credit for finding replacements, despite the delay in the schedule. The Grand Prix offers a total of 300,000 Euros (about $410,000) to the top 10 cumulative scorers. Levon Aronian of Armenia, who won two tournaments and tied for second in another, has already clinched the first prize of 75,000 Euros (about $102,000). More than half of the 14 chess players in Astrakhan retain ...
