Comments/Ratings for a Single Item
Does anyone have any quantitative information about the advantage White has over Black? The kind of thing I'd like to know is: supposing two experienced, average rated players, with equal ratings, play many games against each other until 100 games have ended decisively (not in draws), how many should we expect to have been won by White? Is it 55-45, or 60-40, or what? Supposing our pair of equal players were more skilled than average, does that make it closer or farther to 50-50? Another thing that would be of interest: supposing we experiment with matching many pairs of unequally-rated players, with the stronger player playing Black, until we find pairs in which the White-win, Black-win ratio is 50-50: will we find any consistency in the number of rating points that separate the two players? Does playing White worth 20 points to your rating? 40 points? 100 points??
Mark: I would guess that 16 games between two evenly matched grandmasters usually results in 9 points for White and 7 points for Black. That would represent a 50 point rating advantage, under the former Canadian system. In the New York 1924 Tournament the players with the White pieces scored 28-27 in the first half and 33-22 in the second half. White's total score for this 11 player double round robin was 61 out of 110, or 55.45 percent.
The statistics button in Chessbase 8.0 informs me that White scored +123, =137, -71 in the 331 games played in 17 world chess championship matches from 1886 to 1937. That is 57.85 percent for White. I count 536 games played from the 1948 tournament to Kramnik - Leko (2004), leaving out all the FIDE events after Short and Kasparov left. White scored +140, =325, -71 or 56.44 percent. Draws are getting more common at the highest level - but that is another topic.
it is not very clear and why isn't there more colour?
easy game why dont you make it harder
Yes, Joe. After a King has performed a castling move, it may make moves and captures on subsequent turns. It may not make a capture during the castling move itself.
I'm trying to ask a question. If I am in check by my opponent and I can't move my king to safety or protect it, but I make a single move elsewhere on the board and checkmate my opponent, is it then a draw? Does the rule prohibit my move because it doesn't move my King out of check? Since my move means that both Kings are checkmated, under the rules, no one can move at this point? johnberlin@erols.com
