There is also another reason why computer games are often very long: It happens that one of the engines thinks it has a clear advantage in the endgame, but doesn't search deeply enough to find a win. It will move the pieces around randomly, carefully avoiding 3-fold repetition. When 49 moves have been played, it pushes a pawn somewhere in order to avoid the 50-move draw rule. Then the process repeats itself. I've seen many comp-comp games which are longer than 200 moves. Tord
