Subject: Alpha Pocket Crafty 19.17 SE

Alpha Pocket Crafty 19.17 SE plays the winning move in 63 seconds, the same move
played by Bobby Fischer in a game he played in 1960.  On my machine, Chess
Genius takes 2:33 to find the winnig Rxe3!.  Note the Q is immune from recapture
on f4 by the white king as it leads Bh6 #.

Pocket Crafty 19.17 SE has also set a world record ( to my knowledge) for
opening book size on a PDA.
It currenty plays its book line from a  book installed on the CF Card.
The book is 55MB and it contains roughly 2.7M positions from very game every
published
in Chess Informant Volumes 1 - 89 -- over 90,000 games in all,

Pocket Crafty 19.7 uses the exact same book as that of PC Crafty.  Simply copy
it to the PDA from the PC.

That's all I can right now, except it is not ready for distribution as a number
of issues need to be fixed.
