Hi,

Junior made several mistakes:

1. Closing the position
2. Not playing Bh6 to exchange the black bishop
3. The useless and time consuming bishop maneuver Bg5-e3-f4?
4. Castling long, right into the black attack
5. The lemon a2-a3??, which gives Black a nice target

After 15 moves White was already desperate. You know, in these positions the
strongest programs simply look silly, using a 4,5 GHz processor or not! The
point is that calculating gets you nowhere in closed positions. Even a 5000 GHz
processor wil not prevent moves like a2-a3? Because this move will not lose
within the next 30 plies.

It seems that programmers should have 2 versions of their program:

1. A fast one to play other chess programs
2. A much slower one with a lot more chess knowledge, that can prevent
   games like against Kramnik and Piket.

Today's game again showed that with the right human anti-computer tactics a
chess program looks like a player way below 1800 Elo....
