unkx80: Comment: There are games that last well over 300 moves. Why? Because of the sheer number of kos. Perhaps someone can find these games...
tderz one player of the (2nd?) longest game is Yamabe Toshiro. The game was played 1950 vs. Hoshino Toshi and lastet 411 moves.
Most ko captures in one game were: 59 captures in the game with 363 moves Komatsu Hideki vs. Nie Weiping in 1993.
zinger: Did you mean 400 moves? 300+ move games need not involve ko - there are 361 points, after all. I recently played a 340 move game on IGS with no long kos.
