If I am right, there is something fishy about the Chessbase implementation of
Crafty.

I usually play 5 10, and whenever I reach a simple/blocked,
position and make moves very fast, Winboard-Crafty (the real Crafty)
notices this and spends on average 5s/move, thus saving up time.

Chessbase-Crafty still spends on average 10s/move and keeps a
buffer of 30-60 s. I don't understand why there is a difference.
