Longest game

[sje]

I haven't been keeping track of the longest game played by Symbolic, but the one that just ended must be in the top one percent.

Not a single black pawn was lost.

Hah! actually, Symbolic is rather proficient at losing pawns. Keeping all eight of them in any configuration is rare indeed.

[Tord Romstad]

I'm pretty sure I have seen one or two test games which lasted more than 300 moves, but unfortunately I haven't kept the PGNs.

In CCRL we have a download file called "long decided games" . In there, 300 moves is the longest
