white to play and draw
Robert kindly advised that (translated from Dutch) "...The difficulty in the Behting study is not to find 1.Kc6 ( Houdini sees this as a clear draw ), but to see that 1.Ng7+ looses for white. This is very complicated , a position occurs of queen against 2 knights plus a pawn, that happens to loose for the queen ( with a nice zugzwang ). Please refer to the analysis on chessbase.com. Unfortunately, this analysis lies beyond the capabilities of Houdini 3 on normal hardware..."
So we see that Houdini cant resolve all chess problems yet - but for us, mere mortals, it should be sufficient to help us improve our Blackmar Diemer games. Thanks Robert !
