I've never seen the  2420 USCF rating.  Where did you see that?  In my
experience this is far too high, even for G/30 or blitz games.

It is the strongest portable, especially for endgames because it is the only
portable which has a hash table.  (It is exactly the same hardware and program
as Novag's top-of-the-line tabletop, the Diamond II.  In fact, Novag's high end
wooden board/auto sensory offering is simply their Universal Chessboard bundled
with the Sapphire II.)  Only Novag marketing might claim IM strength. ;)

It is not the user-friendliest portable, since it is calculator style instead of
sensory.  Great training for blindfold games and visualization though...

>Which the exactly strength.?

I run SapphireII on FICS (mostly at 2 1, 5 0, and 15 0).  It maintains a rating
around 2100 in each of the lightning, blitz and standard rating categories, just
to add one more rating to your confusion. :)  This is based on over 5000 games,
certainly more than were played in the SSDF, US, British, German, or Italian
rating pools.  There aren't any other dedicated computers playing on the
servers, which makes comparing ratings between rating pools difficult.  The mean
and standard deviation for the FICS blitz pool is currently 1532 +/- 286 (2022
+/- 500 for just the computers).
