Either bigger hash or having the tablebase file helps quite a bit. Very close
to a draw score:
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.
