September 26[edit]
Chess outcomes[edit]
If draws by agreement or timeout (other than those known to have been book draws) are excluded, what percentage of international-tournament chess games are won by white, and what percentage by black? NeonMerlin[1] 03:06, 26 September 2009 (UTC)
- There is an article on First-move_advantage_in_chess. Bo Jacoby (talk) 08:05, 26 September 2009 (UTC).
- There are also stalemates, draws due to repeated board position, draws due to insufficient material to mate, and draws due to no piece taken in (50?) moves. Did I miss any ? StuRat (talk) 13:12, 26 September 2009 (UTC)
- According to Krabbé's Chess Records, Kosteniuk defeated Fressinet in 237 moves (Villandry 2007, rapid) but Fressinet could have claimed a 50-move draw much earlier (remember, that has to be claimed). —JAO • T • C 12:06, 28 September 2009 (UTC)
- And, as list of world records in chess reports, Fressinet's election was informed; having earlier in the tournament protested Viktor Korchnoi's invoking the fifty-move rule, arguing (unsuccessfully) that such a draw cannot be had in a blitz game in which moves are not recorded, he admirably subjugated self-interest to consistency. 76.230.224.226 (talk) 19:10, 28 September 2009 (UTC)
- If you count theoretical positions that were not actually played out, Fifty-move rule mentions a winning position which requires 517 moves for a capture. -- Meni Rosenfeld (talk) 17:13, 28 September 2009 (UTC)
