90'+30" small free engines tournament - Toga Wins !!

[Spock]

This was a very close finish, but Toga managed to take it. A very enjoyable tournament, for me anyway...

I notice one time loss in the 4th cycle, which I've left. Bright didn't seem happy playing under Arena or maybe with ponder on. It caused the GUI to hang about 3 times during this tournament. My previous 90+30 without Bright ran perfectly.

If you remove #2 from the results #3 does not move up to #2 but to #1. Opps, that is #1!!

Of course there is this also.

I have seen people refer to Rybka as the #2 free engine. I am kind of curios as to what #1 is. Maybe a new release I don't know about?

Thanks for the tourney. As I expected, with my very few free CPU time, my tourney will be the last tourney of this kind in finishing, even though I use much faster time controls. And thanks for the pgns, as after all, what matter are the games.

I expect Toga to win here as well, and Rybka BETA 32bit is having a lot of trouble
