Subject: A test position(finding mate in 32 if you believe Deep Fritz)

Author: Uri Blass

Date: 13:02:09 06/12/01

This position is from a game of Fritz6 that was posted by James walker

[D]8/8/P2k4/1P6/2P5/K7/8/1r6 b - - 0 1

Deep Fritz(without null move pruning) says Kd7 mate in 32 at depth 20)

I gave it the following position

[D]8/8/Pk6/1P6/2P5/1K6/2r5/8 b - - 0 1

and the game moves that lead to the first diagram:
Rc1 Kb4 Rb1+ Ka3 Kc7 Ka4 Kd6 Ka3

Deep Fritz used 128 Mbytes hash and tablebases including KR vs KPP.


Can your program find the forced mate?
