Hard positions,

           Fritz 5                 CM6000                   Rebel 10
test 1  Played c5 at 12:30     Played c5 at 58:36      could not find >8hr

test 2  Played Rxe6 at 4:02    played d3xg6 at 6:01    could not find

test 3    0:00                    0:00                 could not find

I hope I did the position correctly. If not post the positions in epd.
Rebel 10 could not solve the tests at all, because Rebel 10 thinks that the sac
leads to a draw all the way up to move 19. CM6000 in test 2 played d3xg6 which
also looks winning, if not post and I will keep searching the position.

I used a P II 333 for all position and programs.
