Hi Jud and all, a 262 move endgame was apparently discovered about 4 years ago: http://www.chessbase.com/newsdetail.asp?newsid=239 But the longest forced win section at http://en.wikipedia.org/wiki/Endgame disagrees: it says that it was only last October that a 292 move endgame was announced, breaking an old record of 243 moves. But in May there was a 517 move endgame win discovered! One announcement of that is at http://216.25.93.108/forum/viewtopic.php?t=2860 and it's also mentioned in the wikipedia article. --Joshua Zucker On 8/23/06, Jud McCranie <j.mccranie@adelphia.net> wrote:

A note about a related problem. In the generation of optimal-play endgame tablebases, they assumed that no forced win would take more than 255 moves. Well, a few months ago they found one that took (I think) 312 moves.
