Subject: Test your passed-pawn evaluation function!

Author: Jaime Benito de Valle Ruiz

Date: 02:18:15 01/13/04

In this position you can find several passed pawns for both sides (this is
particularly hard for my engine), plus three connected passed pawns after the
sacrifice 1. Rxe7, which is an obvious move to consider for human players.
How much is worth 3 connected passed pawns in the 5th and 6th versus a rook
here?

[d]3k2r1/r3p2R/4P1b1/2PP1p2/p5p1/8/1B6/4R1K1 w - - 0 1

Does your engine find this move?
(Mine doesn't. My passed-pawn goes mad giving extreme values for both sides
during eval, making the search oscillate from one move to another all the time)
