Chess Tiger does not use bitboards. That's why it runs fine on 16 and 32 bits
processors (and will still run fine on 64 bits ones).
In 10mn/game on my Palm it will reach 5-6-7 plies typically.
That means that some variations are cut at 3 or 4 plies, and some others are
extended to 20 plies (or more).
From what I have seen so far with the SSDF tests, Chess Tiger for Palm could be
a little bit under 2100 SSDF elo.
