Longest human chess game 269 moves.

[mwyoung]

Houdini 3 Vs. Rybka 4.1 are now at 270 moves at a 40/2.5 hours time control chess game. And still going strong in a KRRNPPPPP Vs. krrnppppp non locked endgame.

The programs have been playing for over 2 days, this game could go over 300 moves at tournament time controls....

Houdini has a slight edge in the position because of a outside pass pawn.

The longest tournament chess game (in terms of moves) ever to be played was Nikolić-Arsović, Belgrade 1989, which lasted for 269 moves and took 20 hours and 15 minutes to complete a drawn game.

I don't know the longest computer chess game at tournament time controls, but I sure it is well over 300 moves.

I have seen several longer games, thou I guess less spectacular than the one you mention ...

I have publish the Houdini 3 - Rybka 4 game on you tube. There is nothing spectacular about the game, other then it was very long 290 moves, and took about 36 hours to play.

[carldaman]

I have seen several longer games, thou I guess less spectacular than the one you mention ...

Hmm... this wasn't a serious game now, was it?!

[simonhue]

Hmm... this wasn't a serious game now, was it?!

Hm, just googled it - looks as it was a blitz game.

[carldaman]

Hmm... this wasn't a serious game now, was it?!

Hm, just googled it - looks as it was a blitz game.

Erm... that wasn't the point ... look at the actual moves played!

[simonhue]

LOL seem the only point of this game could have been to produce the longest game with a GM.
