OK, apparently I did not understand the question. So it is the opposite of what
I have described. Set it to game in 3 if you are manually operating a game in 5.

This time I'd better simply admit that I don't understand your question.
If you are asking if Tiger plays "at full strength" in short time controls, I
would answer: yes. Tiger is not optimized for a particular time control. You can
use it at any time control. Well, maybe it's not really true for time controls
under 1 minute per game, because the graphical interface is maybe going to eat
too much processor time, but for time controls longer than 1mn/game, go ahead,
it's OK.
In short: I accept the challenge against any chess program at any time control
(provided equal hardware and equal time controls are given to both).

Maybe after you make the move it can see a deeper combination and realize it is
not as good as it thought before. But this is a normal behaviour of any chess
program, just forget about it...
