You guessed right. I could change this and tell the program to think a little
bit more when he has found a mate, just in case a shorter mate exists.
However, this would not change the issue of the game, nor the playing
strength... It's only a matter of elegance.
Note that you can force Tiger to find the shortest mate by selecting the
"Infinite" time control mode. Chess Tiger will not stop on the mate in 4 and
will find quickly the mate in 2.
