Thanks Hagra for your confidence in my hurried analysis. Nvertheless it is not
yet proven, that Nd6 is better, perhaps both moves are equal. It's a very
complicated and unclear position. I would appreciate any analysis regarding this
position.

But I thank you for pointing out the quality of the WM-Test, where in the first
50 Positions only one position was found to be unclear. I too think this is a
pretty good percentage for a testsuite.

regards Joachim
