I just saw Harvey's move. I have 11.Bd2 as best (ponder move?), let's see if something changes that makes me change my mind...

From this position, I ran 100 games, 48 wins, 4 losses and 48 draws at a bullet time control in favor of black - which would tend to under represent the number of draws which would occur at a higher level of play.

Nothing happened.

I spent a great deal of time checking Qc2 Bf5 Nd6+ Bxd6 Qxf5 and I think that'd be Harvey's dream variation. And I don't even know if Bf5 is best there, so that's clearly a red flag.

How did you do this? Did you use your Variety feature?

Bd2 follows Stockfish-dev's PV, but Bd6 deviates. Evaluation before 11. Bd2 was -1.64 at depth 63.

Was it going to play Qd7?

I have saved the previous PV for future discussion.

I'm surprised you use ponder. I've never found any use for it.
