The issue is this.  The other night I watched Crafty vs a commercial program,
crafty ended up with a lone king, the other program had a king rook and pawn.
It obviously had the krpk table, but apparently not the kqrk table.  It advanced
the pawn to the 7th and then moved idly around until the game ended in a 50 move
draw.  All the while crafty's eval was at something like -Mat09 or something...

The moral?  Don't resign against a computer, you never know _what_ will
happen...  That is why I don't resign when playing a machine.
