As you may have noticed, I always add the elo system I am using when I talk
about Chess Tiger's strength.
My evaluation is 2100 elo FIDE (SSDF) on a standard Palm. Around 2200 elo FIDE
(SSDF) on an overclocked Palm.
And yes, I do claim that Chess Tiger for Palm is the strongest chess program for
the Palm. I have evidence of that and it is published on the website
www.chesstiger.com
