| Posted by gestalt uskidscompute.com 1/15/2003 16:13:04 Play online chess |  Subject: playing the percentagesMessage: This may be a stupid question but - If a hypothetical study of all Grandmaster games ever played was carried out to identify which openings or defences have historically produced the most (1) wins for white and (2) wins for black - which openings would come at the top of the list? And (heres the stupid bit!) would it not be logical for players to employ these openings most if not all of the time? |
| Posted by myway316 uskidscompute.com 1/15/2003 16:19:06 Play online chess | My guess would be... Message: ...for White the Ruy Lopez,for Black the Sicilian.As to the rest,the results are entirely dependent on the skills of the player. Too many players play what's "in style",blindly following the latest GM analysis,without doing their homework.They also play openings that are totally unsuited for their style of play. |

Yes, according to a study by Swedish researchers. Called “Beauty Queens and Battling Knights: Risk Taking and Attractiveness in Chess,” the study used a large data set of results from international chess tournaments and cross-referenced them with photographs of 626 of the chess players — almost half of them women — whose attractiveness was rated by at least 50 independent observers. The study concluded, “Our results suggest that male chess players choose significantly riskier strategies when playing against an attractive female opponent, even though this does not ... |
| Posted by getoutofhere uskidscompute.com 1/15/2003 16:29:32 Play online chess | but Message: In general your idea is right. Commonly played openings like the Ruy Lopez and the Queens Gambit have excellent winning percentages for white. For lowly players like myself the differences between openings are more a matter of personal preference than theoretical soundness. ——— Chess grandmasters use twice the brain : Study — It may take years of hard work to become a chess grandmaster, but it gives a real boost to the brain – for working out chess problems, at least. It seems expert chess players use both sides of their brain to process chess tasks, rather than just one. Merim Bilalic at the University of Tübingen in Germany used fMRI to scan the brains of eight international chess players and eight novices while they identified either geometrical shapes or whether the pieces on a chess board were in a check situation. The expert players were quicker at solving the chess problem, activating areas on both sides of their brains as they did so. The novices used just the left side. Bilalic had expected ... |

But as myway said, its really how well you can play a given opening. ——— Chess: The best form of defence — It may be a cliche, but in a tight spot attacking can be the best way forward. RB: Hands up those of you who plumped for 1 Rb1. There's no disgrace if you did. Peter Leko, rated 2743 when he played this game, opted for exactly that and went on to draw. It's the move I thought of when I first came across the game, in Drazen Marovic's Secrets of Positional Chess – but is it the best? After a series of miserable failures on my part, the boot's on the other foot this week – it's Dan's turn to solve the chess puzzle. DK: Black's rook has just swept down to c2 attacking the pawn on b2, and although that could be defended with 1 Rb1, my gut feeling tells me not to look at this too deeply ... |
| Posted by soikins uskidscompute.com 1/16/2003 00:42:50 Play online chess | e4 move Message: Some say that e4 is the best first move, but that doesn't mean that everyone has to play it. Some players (like me) just don't feel comfortable in open games. So everyone should choose the opening that he likes best (and knows best), it doesn't matter what stats say. Another thing: GM Shipov once wrote about statistical position evaluations. Sometimes you can see that after an opening black is a little bit better, but statistics shows that white wins more often. Why is that? Because people are not machines the don't play positions they don't like so good as positions they like, therefore it sometimes is better to choose an "inferior" opening, but the one you like, than "the best" opening that you just don't enjoy. You will score more points in the "inferior" opening. soikins ——— America Has a New Chess Grandmaster and Three New International Masters — United States chess has rarely, if ever, had a week like the one that ended Saturday. On Saturday, four Americans earned titles at the Berkeley International chess tournament. Samuel Shankland, 19, the reigning United States Junior Champion, became a grandmaster, while Keaton Kiewra, 23, Daniel Naroditsky, 15, and Conrad Holt, 17, all qualified as international masters. Kiewra actually earned a grandmaster norm — the first of three needed for the title — but he still must raise his international rating above 2,400 to satisfy the requirements for the international master title. That is often less difficult than achieving the norms. Tatev Abrahamyan, 22 (she will be 23 on Thursday), earned ... |
| Posted by peppe_l uskidscompute.com 1/16/2003 03:28:40 Play online chess | Actually Message: I recall reading 1.d4 is statistically best move (not that it proves anything). ——— China Rises, and Checkmates — If there’s a human face on Rising China, it belongs not to some Politburo chief, not to an Internet tycoon, but to a quiet, mild-mannered teenage girl named Hou Yifan. Ms. Hou (whose name is pronounced Ho Ee-fahn) is an astonishing phenomenon: at 16, she is the new women’s world chess champion, the youngest person, male or female, ever to win a world chess championship. And she reflects the way China — by investing heavily in education and human capital, particularly in young women — is increasingly having an outsize impact on every aspect of the world. Napoleon is famously said to have declared, “When China wakes, it will shake the world.” That is becoming ... |
| Posted by atrifix uskidscompute.com 1/16/2003 06:31:17 Play online chess | Statistics Message: First, such studies are not hypothetical; chess statisticians devote a fairly good amount of time to figuring out the W/D/L percentages. But in practice these statistics mean very little. First of all, you have to make sure you get a good sample--games lost by blunders or played by weaker opponents will skew your sample. Secondly, this fails to take into account your own strength, for example, Kasparov, an expert on the Scotch Game, will post a far higher winning percentage with this opening than other GMs. Thirdly, opening evaluations tend to change with time--for example, less than 100 years ago, the Sicilian was considered among the top GMs to be theoretically unsound in comparison to 1... e5. Today even club players know this is nonsensical. So, while the idea is good in theory, trying to incorporate high GM winning percentage openings into your own repertoire is usually met with extremely mixed success. A better way to win games is to play what you feel comfortable with. And if you really want a good statistical sample, look at your own games and figure out which openings give you the best winning percentages personally--then see if you handle certain openings well or mishandle others. |
| Posted by triangulator uskidscompute.com 1/16/2003 13:30:57 Play online chess | I think Message: the ruy lopez for white, an the sicilian as black. as said before no matter how good an opening is if just 1 line refutes it, it is dead. It is just a matter of taste: e4 leads to wild positions as in the siclian or, quite positions such as the petroff. d4 in my opinion leads to fun positions that are all simalar in some way in terms of plans for both sides and the positions- though this is not always true best wishes triangulator |

| Posted by druleeparsec uskidscompute.com 1/16/2003 16:50:26 Play online chess | Message: In Fritz there is an opening book tab. On that tab as you make a move it will show the top 2 to 10 moves from it's opening book database. But here's the cool part: It also shows how many games are in it's database that use that move and what was the win percentage for the person who made the move. So somebody has done the work you asked about. BTW, Fritz 7 is now on sale at chessbase USA cheap. I won't quote prices here but you may want to go check it out. [disclaimer: I'm not afilliated with Fritz or Chessbase, I'm just a satified customer etc yada yada yada] |
