Posted by wanstronian uskidscompute.com 11/08/2005 01:13:07 Play online chess	Subject: Value of preventing castling Message: What value would you put on the prevention of castling by forcing the King to move early? Would you forfeit a piece to achieve this and if so, which one?
Posted by tyekanyk uskidscompute.com 11/08/2005 01:59:26 Play online chess	Hmm... Message: It depends alot on the kind of threats you can produce, and if the kind is truly exposed, otherwise it may not pay off, beacause although he may have ssome ealy coordination problems, but after that's done with the material will start to tell.
Posted by ionadowman uskidscompute.com 11/08/2005 02:31:03 Play online chess	Preventing castling... Message: Generally speaking it's not worth a whole piece. You need a lot of compensation in terms of space and time, e.g. the K well exposed. But try it out with someone. The Jerome Gambit runs 1.e4 e5 2.Bc4 Bc5 3.Bxf7+ Worth a try do you think? Cheers, Ion ——— 2011 Tal Memorial — I am reporting from the 2011 Tal Memorial, held Nov. 16-26 in Moscow. I am also 10 hours later than my St. Louis readers, so that means I am reporting from the future! The Tal Memorial is named after Mikhail Tal, the eighth World Chess Champion and a Soviet chess legend. This prestigious event features 10 chess players, all grandmasters, in a round-robin format, and this field is quite possibly the strongest of any chess tournament, ever. The players in the event, and their rating/world rank according to FIDE, the World Chess Federation, are as follows: Magnus Carlsen: 2826 (1), Viswanathan Anand: 2811 (2), Levon Aronian: 2802 (3), Vladimir Kramnik: 2800 (4), Vassily Ivanchuk ...
Posted by chuckventimiglia uskidscompute.com 11/08/2005 06:23:01 Play online chess	If the Queens are off the.... Message: board castling can be a detriment. The King becomes a fighting piece and should be positioned for that purpose for the end game. Castling can put the king in a backward position for end game play. ——— Armenia's killer chess move — Bravo to the former Soviet republic for putting chess on the curriculum. But beware â€“ this game is more compelling than life. I have diverted myself briefly from playing online chess to write this. I've been keeping a log of the games I've played this week, and they number more than 60. At some point in the last five years, mainly thanks to the fact that chess and the internet are made for each other, I became a chess obsessive. Those 64 squares in which a life-and-death battle are waged have become the cornerstone of my existence. In this, I like to think I am in good company. "Chess is my world," said the former Soviet world chess champion Mikhail Tal. "Not a house, not a fortress where I hide myself from life's hardship, but ...
Posted by velvetvelour uskidscompute.com 11/08/2005 13:55:01 Play online chess	Message: In an open position with a fluid center preventing castling is indeed worthwhile, often worth the sacrifice of a pawn or two, as it is in certain lines of the Evan's Gambit, King's Gambit, and other double K-pawn gambits. Possibly even a piece could be invested depending on the position (you usually need a lead in development/initiative with a follow through of palpable, difficult to defend threats for the piece, i.e. the Muzio Gambit, certain positions where one sacs a bishop for pawns on h3/g4 over a castled king). It teaches one, if nothing else, on how to keep the pressure on via necessity, otherwise your advantage with fizzle and one will simply be left with a material deficeit. In a closed position, though, the nature of things changes considerably. If the center is locked and pawn exchanges are unlikely, a King is often safer in the center (as it is in variations of the French Defence and certain ones of the Sicilian, Benoni, and other defences of a closed nature) then scuttling it over on a wing, because the second player knows "where your king lives," and can often start a decisive build up of material w/a pawn rush to come crash the house. When the queens are off the board, often early in the game heading for a queenless middlegame, the peril of a centralized king becomes much less and you often want it in the center where it can better keep an eye on things and become favorably activated. As an aside, the Jerome Gambit is garbage and shouldn't be played. It also arises out of: 1) e4 e5 2) Nf3 Nc6 3) Bc4 Bc5 4) BxP KxB 5) NxP NxN 6) Qh5+. There are far sounder sacrificial lines in chess to start a king-hunt without resorting to such desperados. ——— Armenia makes chess compulsory in schools — Authorities say teaching pastime to primary school children is about building character, not breeding future chess champions. Tiny Armenia is a big player in world chess, and a new gambit could make it even bigger: mandatory chess in school. The former Soviet nation has made the game part of the primary school curriculum along with such standards as maths and history for children between the ages of seven and nine. Chess is a national obsession in this country of 3 million people tucked away in a corner between Turkey and Iran. The passion was fostered in modern times by the exploits of chess champion Tigran Petrosian, who won the world chess championship in 1963 and successfully defended his title three years ...

Message: Velvetvelour sums up pretty nicely occasions in which a K in the centre can be a liability, and when it can be a hazard. As for her gratuitous remarks in respect of the Jerome Gambit...well, she's right, broadly speaking. It ought to lose for White, with best play, but I think there is value in discovering things for oneself, hence my suggestion about trying it. I wouldn't play it in a team game, but perhaps you can use some of your other games as 'training' games in which you discuss opening ideas. Perhaps someone will accept a challenge to play a pair of games, one White, one Black, with this, or some other fixed opening agreed beforehand. You need not have your rating riding on such games... Anyway, just an idea... Cheers, Ion ——— On Chess: Underdog Israelia threat to Anand — Boris Gelfand, an Israeli chess grandmaster born in the former Soviet republic of Belarus, has had a singular career. In 21 years of tournament play, excelling at both traditional and rapid chess, he has won, finished second or tied for second in 43 of 52 tournaments. Yet he hasnâ€™t been able to gain the title of world chess champion. Seeming to improve with age, Gelfand achieved his best result in 2007 when he tied for second with the then-reigning world chess champion, Vladimir Kramnik. The world title tournament was won by Viswanathan Anand, who remains world chess champion. In the spring, Gelfand will square off with Anand in a match for the title. Gelfand stands in sharp contrast to his ...
Posted by spugmyers uskidscompute.com 11/09/2005 06:19:31 Play online chess	According to Heisman... Message: This reminds me of a "Novice Nook" article by Dan Heisman. -> www.chesscafe.com He says: "In IM Larry Kaufman’s excellent Chess Life article on isolated pawns, he stated that the single worst positional disadvantage was doubled isolated pawns on a semi-open file. Such a ruined pair of pawns was worth, on the average, only slightly more than one pawn – they had lost almost a full pawn in value. This is an interesting observation which allows us to draw an important and practical “powerful” conclusion: The single highest valued positional factor is worth slightly less than the least valued tactical factor (a pawn)." ——— chess games — chess tournaments
Posted by bonsai uskidscompute.com 11/09/2005 09:33:03 Play online chess	Message: Mmmh, maybe that's not even too wrong for a single isolated factor, but we all know these occasional cases where one can have purely positional compensation (i.e. not a situation where you clearly win due to a sacrifice or can clearly get your material back anyway) for more than a pawn (sicilian exchange sacrifices on c3 being a typical case).
