Subject: Searcherx-Crafty rook ending

Author: Ricardo Gibert

Date: 21:18:55 01/26/03


I played a couple of 15 10 standard games against Crafty on ICC from the
Searcher-Crafty CCT5 rook ending position, which had ended in a draw. The object
was to see if the ending was really an easy win for Black i.e. if *I* can win
it, anyone can ;)

I played both 61...b5 and 61...Re8. The first game with 61...b5 got a little
trickier than expected and the second was very simple, so I guess it could be
said the position is "marginally easy." For those who are curious, here is the
PGN for both games:
