Subject: Chess Tiger 14 floored in 20 moves.

I think this was a nice attacking game from Pro Deo Betazoid T8. 10.g2-g4 seems
fairly risky, first move after the opening, it is still established theory.
10..b7-b5 11.g5 maybe not, I haven't checked? 14.Ndxb5 is a nice sac, and
probably not hard to find. Chess Tiger was unlucky with 10..b5 I think and used
up a lot of time after. I had to replay the game since Tiger caused a time-out
first time with 12..Nc5, taking longer than 40 minutes for this move. But,
replayed, it was over before the time trouble could begin.

All games Celeron 500 MHz, 13 and 12 Mb HT, EGTB's for Chess Tiger, 40 moves in
2 1/2 hours.
