The WM-Test position (Gurevich-HJS in CSS) Nr. 55 is this:

[D]5b2/p2k1p2/P3pP1p/n2pP1p1/1p1P2P1/1P1KBN2/7P/8 w - - 0 0

Fritz 8 have find here the nice win move 1. Nxg5!! after few minutes only!

But Today I read in CSS, and what I must seen?
A very interesting another position!

THE NEW TEST POSITION:

[D]5b2/p2k1p2/P3pP1p/n2pP1p1/1p1P2P1/1P1KB2N/7P/8 w - - 0 1

Analysis by Fritz 8 (128 MB für hashtabellen):

1.Kc2 Sc6 2.Kd3 Sa5
= (0.00) Tiefe: 23/52 00:12:03 459396kN

:-))

"The motiv with Nxg5!! is egual" in both positions!

But in the new position Fritz 8  never can find the nice move 1. Nxg5 !

Hopla! :-))

Can Your program find this move 1. Nxg5  in the “new position”?
