After move 59 Rybka immediately understood that Houdini's move was incorrect. It took Houdini a couple of moves more to smell the trouble though.

My guess is: it was not Rybka 4.1 Beta 6. It must have been an Ivanhoe. Otherwise you would send us Rybka 4.1 Beta 6 codes.

Enst,
ernst wrote: After move 59 Rybka immediately understood that Houdini's move was incorrect. It took Houdini a couple of moves more to smell the trouble though.
Quite interesting, the key position occurs after black's move 61:
[D] 5r2/8/1p1p2r1/p2Pp1p1/2P1N1kp/1P3p2/P4Q1K/8 w - -
Houdini takes ages to see that Qxb6 is not a draw. In my test run it required Depth 29 and more than a billion positions. One of the difficulties appears to be that the move Kf4 is not easily considered by Houdini (it's too unsafe).
I will certainly investigate this more in detail for Houdini 2.0.

Gerold, nothing's been decided yet, in about 6 to 9 months is probably a reasonable estimate.
