Message: When making the piece move, the mover ought already to have planned a response to an attack by a flank pawn: an exchange on the c-file (if it's a bishop); a sac on f7 (if you've just played Ng5); a retreat - and where to? Sometimes it's not a bad idea fort White, say, to develop a bishop at d2 via g5, losing a tempo, but inducing a small but exploitable weakness in Black's K-side. I've done that myself. On the Black side of a Sicilian Defence, ...a6 is often useful even if it doesn't hit a bishop, partly as apreparation for a central thrust, but also because Q-side expansion is on Black's agenda anyway. So 1.e4 c5. 2.Nf3 d6 3.d4 cxd4 4.Nxc4 Nf6 5.Nc3 a6, the Najdorf Variation, is a very popular line. That little move hides a good deal of aggression. The Sicilian Kan System also involves an early ...a6. Conversely, the Two Knights' Defence often features an early advance of a White Knight to g5: 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5!? ... I think the debate whether this is sttronger than 4.0-0, 4.d4 or 4.d3 is still ongoing. Of course it's pointless hitting the knight now. Black will usually play 4...d5 5.exd5 and now 5...Nxd5 is very risky owing to the enormous attack White whips up: the Fegatello, a.k.a. the Fried Liver: 6.Nxf7 Kxf7 7.Qf3+ Ke6 (forced if Black wants to keep the material); 8.Nc3 Ncb4 (the irony of it!) 9.a3! (biffing the knight , hoping to dislodge it fronm its defence of d5. The fork on c2 looks tempting, at that!) 9...Nxc2+ 10.Kc1 Nxa1 11.Nxd5 etc. All this is theory, which continues for several moves more yet. Black has better alternatives at move 5, 5,,,Na4, the "Main" line turning out rather well for Black, despite the pawn deficit. But even at move 4, Black can seriously consider ignoring the attack on f7 by playing 4...Bc5!? Now, if 5.Nxf7 Black has the astonishing 5...Bxf2+!! 6.Kxf2!? (6.Kf1 may be better) ...Nxe4+ 7.Kg1 (I had someone play 7.Ke1?? against me once on GK 7...Qh4+ 8.g3 Nxg3 9.Rg1 Ne5+ 10.Rg3 Nxg3 0-1) 7...Qh4 with an attack probably strong enough at least to balance White's. The alternate capture at f7, 5.Bxf7+, less ambitious is perhaps the harder for Black to meet: 5...Ke2 whereupon White usually retires the bishop to b3 or d5. In the following OTB game, the presence and absence of the flank pawn moves under discussion prove to have further impact: White: N.N. Black: IAD 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 Bc5 5.Bxf7+ Ke2 6.Bb3 Rf8 7.0-0 h6 The first of the flank pawn moves, played to drive back the knight, and relieve some of the pressure on the light squares - in other words, to prepare to advance the d-pawn. 8.Nf3 d6 w 9.d3?! ... Now this is one point where White might have been better advised to prevent Black's next move by 9.h3! 9...Bg4! Threatening, among other things, to bring a knight in to d4 thence to break up White's K-side pawns. 10.Be3 ... (10.c3 came into consideration) 10... Nd4 11.Bxd4 Bxd4 12.c3 Bb6 13.Nbd2 Qd7 14.Qc2 Rae8 15.h3? ... b A real bad-luck pawn. Correct at move 9, here it is merely weakening: 15...Bxh3! Something you sometimes have to watch for if you want to biff bishops! 16.gxh3 Qxh3 17.Nh2 ... Played to protect g4, but maybe a strike at the centre by 17.d4 offered more hope? 17...Ng4! 18.Nxg4 Qxg4+ 19.Kh1 Qh3+ 20.Kg1 Rf4 21.Qd1 Qg3+ 22.Kh1 Rh4#. I guess in the end you have to think beyond the flank pawn move, and indeed beyond the piece moves against which the flank pawn move is directed, whether as an attack or a deterrent. If the move is part of a longer term plan, or if allowing a piece to land on the "Knight-5" square will really cause you trouble (as indeed it can, quite often) then probably it's OK, but if it's "off the cuff" or "can't think of anything better to do right now", then it's probably un-OK. Cheers, Ion ——— Making the Case for, and Against, Chess as an Olympic Sport — Could chess be an Olympic sport? Such an idea may seem absurd to some people, but the World Chess Federation has been lobbying the International Olympic Committee for years to include chess in the Games. As part of its efforts, the federation even instituted drug testing to bring chess into compliance with the committee’s rules. (Players have grumbled about this, pointing out that aside from caffeine, there are no drugs that can plausibly help them play better.) In making a case for chess, Kirsan Ilyumzhinov, the president of the federation, has said that curling is essentially “chess on ice.” The Olympic committee has granted the federation status as a Recognized International Sports Federation, but ... Posted by savage4731 | nsa-hitachi.com 8/09/2008 19:55:57 Play online chess Message: 1) It wastes a move that could be used to develop a piece. 2) You can always play it after the pin without a loss of time. 3) It weakens the kingside pawns. 4) Pins arent always bad. For example, the Bxf7+ then Ng5+ then Qxg4 sac. Or the Bg4, Be2, Nd4, Nxd4 trick. Also, using the g-file to attack after Bxf3, gxf3. Also, Legall's mate. 5) The h3 pawn can become a target esp for bishop sacs. 6) After h3, g3 can become weak. Esp. If black is pinning the f2 pawn with a bishop. 7) If your opponent captures the knight with the bishop that gives you the two bishops. 8) Its a bad habit to get into: i.e. making mechanical moves and not paying attention. 9) Its passive. Which not only hurts your chances in the game but passive play will slow down your development as a player. 10) You shouldnt automatically assume things like doubled pawns are bad. 11) You should be careful with pawn moves because you cant move them back. 12) You should be playing to control the center in the opening not making pointless flank pawn moves. 13) When I see those kinds of moves against me I know its usually an easy win. 14) A lot of times beginners will think they can easily win a pawn. For example: 1.e4, e5 2. Nf3, Nc6 3. Bb5, a6 4. Bxc6, dxc6 5. Nxe5. But they miss 5...Qd4!. Chess isnt that simple otherwise no one would play it. If you find yourself losing pawns like that its because you're making mistakes and/or not seeing the whole position not because you didnt prevent the pin in the first place. Usually beginners make that kind of move because they're afraid of missing something. Its better not to play out of fear but to play your best and if you make a mistake to learn from it. ——— On Chess: Game is brainy mix of theory, practice — The frequent emphasis on rote learning is decried by critics of formal education. Learning is often reduced to reproducible sound bites amenable to multiple-choice testing. The result can be a learned incapacity in making complex decisions demanding fluid thinking and purposeful action. We often hear from those who use chess as an educational tool that “Chess makes kids smarter.” But why? Chess, like other games, is a testing ground that combines theory and action. It is no accident that the best performers in sports are often effective men and women who achieve new successes when their athletic careers are over. Playing chess involves a continuous mental process of applying and modifying concepts to ...

Kramnik made a clean sweep of the four Englishmen. His key game was in the penultimate round against Luke McShane who till then was a contender for the €50,000 first prize and still finished a strong €15,000 richer fourth. Carlsen was only third, yet the combined elite chess events at Moscow last month and London boosted the 21-year-old Norwegian's status as top dog, second only to the retired Garry Kasparov on the all-time ratings. Carlsen was unbeaten in both chess tournaments, whereas Kramnik and ...

This stellar result catapults Hikaru back in the top 10 after his less-than stellar performance in the Tal Memorial in Moscow, where he finished in last place. Another chess player, Vladimir Kramnik, had a similar turnaround. Kramnik finished next to last in Moscow, but he came back to win the London Chess Classic. Hikaru Nakamura secured second place with a sharp tactical victory over Michael Adams in the final round of the London Chess Classic. Adams is England's highest-rated chess player. The tournament in London had a fantastic format, and it featured a little twist in scoring as well. Typically, a win is ...
