| Posted by johnholland ability-tw.com 8/21/2002 05:40:29 |  Subject: bishop&knight vs. lonely kingMessage: The technique for mating the lonely king with bishop and knight is easy once you have the king in the corner with opposite color of the bishop. However i find it rather difficult driving the king to that corner by force from an arbitrary start position. Is there a general technique for accomplishing that ? thanks for your help JH | ||||||||||||||||||||
| Posted by bafverfeldt1981 ability-tw.com 8/21/2002 06:46:59 | yes Message: Practise it. There is some technique regarding triangle thinking... however just imagine red squares where the other king can't go and force him to the last rank. afterthat remember that it is possible to checkmate anywhere on the last rank if the king won't move to the corner where the bishop can mate it. | ||||||||||||||||||||

Alex ——— Gata Kamsky wins U.S. Chess Championship — Gata Kamsky of New York won the U.S. Chess Championship on Tuesday in St. Louis. In an odd finish to the 24-player event, Kamsky drew to break a tie with Yury Shulman of Chicago. The chess tournament began with seven conventional rounds. Then top scorers Kamsky, Shulman, Alexander Onischuk (Baltimore) and 2009 chess champion Hikaru Nakamura (St. Louis) qualified for a round robin to determine the top four places. Kamsky and Shulman scored 2-1, while Nakamura and Onischuk tied for third at 1-2. In the game that decided the title of chess champion and the $30,000 first prize, Kamsky chose to play Black with draw odds and 25 minutes against Shulman's 60 minutes. Shulman gained ...

But how best to exploit its strengths? The Catalan opening gave Anand two wins in the world chess championship, and has long been popular among the world's elite. It is basically a Queen's Gambit in which White fianchettos. It can be reached via several different move orders, for example: 1 d4 d5 2 c4 e6 3 Nf3 Nf6 4 g3, or 1 d4 Nf6 2 c4 e6 3 g3 d5 4 Bg2. The bishop is tricky on the long diagonal, and the fianchetto provides a safe king position after castling. RB I've always tended to get the Catalan confused with the Bogo-Indian, various Benoni systems, and even ...

I meant forcing the king to the other corner it is necessary to know that mate can arise if opponent's king do not comply. ——— Kamsky Wins United States Chess Champion — It took almost 20 years, but Gata Kamsky is once again the United States Chess Champion. Kamsky won the title on Tuesday by drawing a one-game playoff against Yuri Shulman. Kamsky, who had Black, had draw odds, meaning that he only had to draw the game to be declared winner on tie-break. Though Kamsky has been one of the top chess players in the world since the early 1990’s, he had only won the U.S. Chess Championship once before — in 1991, when he was 17. Part of the reason for the long hiatus was that he almost completely quit playing chess between 1996 and 2004, a period in which he went to school and got a law degree. The playoff for the chess championship had ...

(He had wrapped up at least a tie with a round to go.) The real drama was over who would gain enough points to earn a spot in the Candidates matches or tournament, as the format has still not been settled on. (Nor has a time or a place been announced, which is par for the course with the World Chess Federation.) With a tie for second, Teimour Radjabov of Azerbaijan finished second in the six-tournament series behind Levon Aronian of Armenia.

It's ok english. ——— Kamsky and Shulman Win and Will Play for U.S. Title — They’ll play one game for the title. And if it ends in a draw, they’ll play some more. Gata Kamsky and Yuri Shulman will square off Monday in a game that could determine the United States Chess Champion. Kamsky and Shulman are tied for the lead of the chess championship after both won Sunday. Kamsky, the No. 2 seed, was expected to be a factor in the tournament. Sunday, he beat Alexander Onischuk, the No. 3 seed, in the process breaking Onischuk’s 49-game unbeaten streak in U.S. Chess Championships. It was a tense contest, where neither player had much of an edge for most of the game. According to the Web site of the chess championship, Kamsky even offered ... Posted by johnholland | ability-tw.com 8/22/2002 09:35:47 to allMessage: Absolutegenius is quoting from the book "Essential Chess Endings" by James Howell (you might have mentionded that) which presents the example that you are talking about. That was not the question. The question is " Is there a general technique for driving the king into the opposite colored corner, (or lets say to the edge of the board)". I know the mate should be in the same colored corner as the bishop. Once you have him in the other corner, you can drive him there by forced moves. Posted by bafverfeldt1981 | ability-tw.com 8/22/2002 11:32:39 jhMessage: This was discussed quite a while back and as I said I read something about a triangle thinking technique, I think mentioned from tonlesu or calmrolfe (the two undiputed masters of chess history here). Myself I think in redsquares (squares that opp. king cannot step on).

Unfortunately I didn't save it on my wordprocessor and sadly I don't have time to key it all in again. :( Kind regards, Cal Posted by bafverfeldt1981 | ability-tw.com 8/22/2002 15:25:20 CalMessage: No worries I use to practise in my head ;). However I'm very scared by this Oscar guy because he has stolen my first name AND he seems to play english. Being very paranoid I don't like this ;). Posted by macheide | ability-tw.com 8/22/2002 16:53:06 johnhollandMessage: Once you understand the technique of this basic endgame, practice it in the following way: Put the pieces in one difficult position, and practice it against a friend. In a first stage take your time. When you get more skillful, do the same but with clocks. One of my friends and rutinary adversaries in my city is FM Carlos Garméndez. He loves to set the clocks: 1 minute for him, whatever for his opponent. He always wins with ease. Best wishes.
