Subject: Another interesting Anti-Null move position (from a real game)

White moves and wins!
Can your engine find the right answer and give the proper "crushing" score
(around 9 pawns!) along with a proper PV? How long does it take?
Mine doesn't find anything after a long long time (over an hour), but with
null-move disabled, it takes only a few seconds to show the full PV.
(Some engines find the right answer, but with a small score, an absurd PV, and
they change their mind some plies later)

In this position the black king is in a very delicate position: After a couple
of moves, if the black queen moves, white checkmates inmediately, so both kings
and queens must remain still while pawns play on their own.

Any good suggestion to avoid this problem with null-move?

Regards,

  Jaime

Disable the null-move, and you'll see how easy this position is! (n.t.) Jaime Benito de Valle Ruiz 13:33:32 06/14/04
