what's the longest game you've played?

My longest was 71. We ended in a draw. After I did an analysis with Chessmaster, I had evidently missed 8 chances for mate. I can't see at a depth of 15 however.

Most of my long games have been against people that play right up to checkmate - often in a lost position.

I think that there is a big difference between a long move game that is contested right to the last move and a long move game where the last 30 moves is just slowly working towards an inevitable checkmate.

rrrttt's game is a good long mover game imlo (in my lousy opinion)

A game between 2 computers (that didnt know the rules) was over 400 moves long. Over 200 moves were a K vs K endgame. It finished when an arbieter finally came in.

77 MOVES:
