Subject: F. Dedrle, 1928 ... Correct?

Author: Dann Corbit

Date: 19:51:46 10/11/01


I originally thought I might have found a bug in Yace, but I don't think that is
the case now.  Rather, I think this position is broken.  Does a human player
know if Kf7 really is unbreakable?  If it is, then every program I have tested
is wrong (not unimaginable).

[D]8/8/6K1/k2p4/2p5/2P4p/3P3P/8 w - - bm Kf7; id "(JAFM F. Dedrle,1928)"; c0
"Yace says Kf5 is a draw (analysis 31 plies).  Nobody likes Kf7 long term";

Crafty is the magic word, Scid wants to see
Yace (Yet another chess engine) version 0.99.57

Type help for a (very unhelpful) list of commands
Make sure, you have a file yace.ini in the current directory, with a line:

hash 30M

or similar, otherwise Yace will only use a very small hash of 1M.
