Tony's explanation is what happened, I was standing next to the author of Shark
when he offered it (twice!). This may have to do with Shark winning on time
saturday while Celes had a mate in 5 in the final position. I wouldn't be happy
with 2 wins on time in lost positions. Perhaps if I was commercial and going for
the top spots, but still...

AFAIK, Djenghis doesn't have the repcheck, however Shark does, but it attempts
to _avoid_ it. The author had already mentioned this during the game.

After the game they continued playing and Djenghis threw away it's queen for a
pawn. Apparently it has a bug when a mate is in the pv (see it's game vs Celes
where it went mate in 2 after Qxg5 rather then picking a line which lost some
more material)
