Subject: Another anti null-mover engine position (and endgame study)

Author: Jaime Benito de Valle Ruiz

Date: 10:48:48 02/06/04

This endgame study can be game following the sequence

1.Bd1 g1Q 2.Bxa4 Qc1 3.Bxd7 h5 4.Be8 h4 5.Ba4 Line

[d] 8/3p4/p6p/k2N3B/p7/K6p/PP4pP/8 w - - 0 1

Many engines (Fritz 8, Hiarcs 8, Ruffian 1.01) cannot win this endgame, probably
due to the well known null-move problem for extreme and rare positions such as
this.

They just don't find 5. Ba4

Try your engine after 4...,h4

[d]8/3p4/p6p/k2N3B/p7/K6p/PP4pP/8 w - - 0 1

All the above mentioned engines play 5.Bd7 and get a draw instead of winning.

Regards,

  Jaime
