The most famous game on ICC I remember was between Crafty and Skipper... a 3 0 game that went for 350 moves before a draw. that is 3 minutes on each clock, skipper was manually moving pieces and was a human player in Hawaii. In fact, he is the one that found the 256 move limit in xboard and flagged crafty a few games in 2 0 bullet... reaching 256 moves quite easily without running out of time...
