I guess such things can happen in tournaments.
I haven't seen anything amiss in the games. Others are welcome to download them and take a look.

Cheers, Graham.

Hi Graham,

Is there an easy way to get the pgn of all Stockfish games (your pgn files only comprize 2 rounds each )?

(note: I have had problems with some moves of Stockfish 1.2 opt)

It might be just because Grapefruit does much better against Fruit clones than Stockfish does.

Could be, although I think that derivatives is a more accurate term than clones.

We haven't tested Stockfish 1.2 Optimistic.

Either word works equally well. Clone and Derivative have many definitions several of which overlap.
