The Baron wants to play Nd2 first, and then f6 with an increasing score. Hardware is a slow P4 2.4Ghz:

Hi Richard,
You're aware that whenever you show up here I'll squeeze your soul with my regular question:
When will be a new MP release of the Baron :!: :?:
Standby regards,

I think playing Nd2 first definitely looks better.

I've been running Deep Shredder 11 as well for the last three and a half hours; its last printed output was Nd2 but it has been thinking about f6 now for a good half hour or so. I'll leave it running, it may well switch to it

I'll try Rybka 3 tomorrow unless someone else gets to it before then

It was thinking about f6 as I went to bed, and was still thinking on it this morning, and then before my eyes it finally went for it

Deep Shredder 11 disagrees, with a clear jump in evaluation for f6, although it took over 11 hours on a quad to come to that conclusion

Move: f6!
The Baron wants to play Nd2 first, and then f6 with an increasing score. Hardware is a slow P4 2.4Ghz:

               24->   2:22   0.94   1. Nd2 Qc8 2. f6 Bxf6 3. Rxf6 gxf6

I guess that around ply 26 or 27 crafty will fail high on f6.
