STORM (Century 3.0 -- a customized personality built for attacking) after 54
seconds sees that f6 is not that good (score -0.44 meaning White is better). It
still will play f6, but it realizes that White is better in this position.
Hardware = 700MHz Athlon.
At 3:27 f6 scores even worse -- -0.51
After 5:00 it still would play f6, but doesn't necessarily like the position for
Black (still -0.51).
