Hello Friends of chess!

An interesting test for computers (positionnal test)

White: Ka2,Na4,Qd2,a3,b5,c4,d5,e4,f3,g2,h3

Black: Ka7,Qb6,Bg3,a5,c5,c7,d6,e5,f4,g5,h5

White to play and win OR DRAW
                      -------

I made this test with 2 programs;all indicate Nxb6 which leads to a
draw, BUT with an evaluation between +8 an 10 (that is FALSE)
      ------------------------------------------------------

(in this position ,the eval had to be 0)

The only way to  win is to make pressure on a5 pawn.

Best regards,
ERIC
