Thanks a lot Tim.
Let me add that Chess Tiger still has a problem with Fischer time controls.
The results using Fischer time controls are not optimal, especially when the
increment is big (equal to or bigger than the initial total time for the game).
Sorry for this, I have worked mainly to add chess knowledge in the engine, and
no time was left to improve the Fischer time controls management.
