Thanks for the interesting analysis. I ran Crafty very briefly on the position
after Nxg6 hxg6 Qh6 Be6 Rd3 Bc1! and saw that it gave a +1.80 (more or less)
score after 12 plies, so it obvioulsy isn't choosing Nf3 because it considers
Bc1 to be weaker. This probably means that it thinks Rd3 f5 is a valid defense,
which it isn't. If that's the case, I'm afraid Crafty bit the dust here too. On
the other hand I fed it to Fritz 7.0.0.6 for 6 hours and though it chose Nxg6 at
ply 17, it switched back to Nf3 after with a score a little under a pawn.
