Well, I've noticed that the "number of moves" shown for each game listed on a player's profile is one ply longer than the actual game. For example, here we see that the two reversi games between Hrqls and Nomad were 20 and 18 moves, while they really were 19 and 18. Whenever black is the last to move, a profile shows the game at an incorrect length. I think it's been this way since BrainKing 2.0.

37 moves: http://brainking.com/game/ArchivedGame?g=675119
Look at yours again grenv: only 36.

I remember searching through many profiles some months age trying to find the longest game of Gothic Chess. It would be nice for information like that (maybe average game length as well? :-)) to be stated in the Statistics section or under each game's rules section.

Look how long this game at GoldToken is: http://goldtoken.com/games/play?g=306620
Surely BrainKing can top this?

Here is a link to Omega's game. And it's a 5 wins match, so it will take even longer.
