On crafty with a slow machine with a bunch of other stuff running, a5 gets
picked in about 4 minutes. On a PIII 500 or better, the move will be found
withing tournament time controls at 40/2. Probably within a minute on Bob's
machine, I would guess.

Crafty is one of the smarter programs about pawns, I think. I used to try to
form pawn blockades, but crafty has become positivly *diabolical* in its ability
to prevent me from doing this. Try it yourself.
