Last weekend I had the opportunity to test the updated Nimzo98 and it crashed between 5 minutes and half a hour on a p133, 40MB hash while analyzing the following position: 2r4r/1pq1kp1p/p1b1pp1Q/n7/3NP3/2P5/P3BPPP/3R1RK1 w This position is from the Polgar-Shirov game at Hoogovens, 1998, and the key move is e4e5. (this was not found by Nimzo98, btw) Engine settings (by head): Mobility midgame: 16 Mobility endgame: 4 X-ray midgame: 2 X-ray endgame: 1 Extension table all at 16 Extension threat: 1 Extension capture: 1 Extension passed pawn: 2 Value pawn: 100 Value Knight: 300 Value Bishop: 300 Value Rook: 500 Value Queen: 900 I could repeat the crash several times. I'm don't know if the original (unupdated) Nimzo98 crashes on the same position, but it does on another and that was one of the reasons this fix was released. Kind regards, Ernst.
