Subject: Rybka preview plays Be4 in DB-Kasparov 2nd game 1997!

Hello

I was just looking for some typical testpositions and came along this much
discussed one.

Rybka (on a 1 GHZ laptop) wants to play Be4 (seee below analysis output) which
was actually played by DB.
The move that according Kasparov wasn't a move from a computer but from a human.
Perhaps Rybka is fine-tuned on this position?

Regards

Piet
