I prepared a little by playing Ruffian. My intention was to prepare by playing
about 20 blitz games, but after going 3-0 easily against Ruffian, I got lazy. It
was too easy and that was with 2 6 where I finished each game with more time
than what I started with. In our games, I had to sit on my hands to keep from
playing too quickly. You see, I don't play slow chess anymore and very rarely
even play blitz. I'm a bullet addict.
However, probably a more relevant question is how Crafty would have done against
another engine. I have a feeling the draw against Searcherx may have been due to
a poor eval for Rook endings. I would be interested in how it would fare against
Fritz or Tiger for example.
