Crafty thinks that Qd8 leads to a draw at early depths, but the score drops to -.5 after a bit of searching, while Qg5 never drops negative. I tried this on two other commercial programs and both stick with Qg5 thru 1 minute where I stopped, since this is a blitz game. After Qg5 things get bad... the bishop is lost for two king-side pawns. I see lots of compensation with my current king safety, but not near enough... So Be7 leads to -.5 if Nc4 and Qd8+, and to -1 or worse (worse with a real deep search) if Nc4 and Qg5. Point being of course, that playing Be7 is *not* a good choice... Now if I could only get that point across to Crafty.. :) This is the danger of aggressive play.
