I have been seeing similar problems. At 90 0 it's seldom
to see tactical shots. You either get positionally outsearched
or outevalled.

I am really impressed with Spiderchess. Don't forget they also drew
ChessTiger. They literally walked over Sjeng.

I got out with a cramped game, and they nicely alternated
between attacking both the king and queenside. Sjeng helped
them with h5??? and blew a drawing chance in the endgame too.

The program is very well tested. Also amazing is that they don't
nullmove!

Met zo'n instelling komt daar dan inderdaad ook nooit
verandering in. Kneus ;)

I was praying you would rape crafty in a kingside attack. IMHO
Crafty's kingsafety code is a joke, and I'm hoping someday Bob
realizes that and rewrites it. I could use some new ideas for
mine :)
