After 6. Bd3, crafty had one game (6. ... e6) for black in the enormous.pgn
book. It didn't trust just one game (I have no idea how one move got in there
since I told it to discard moves played less than 10 times, but that is
something else to debug later). so it did a search for yace to find something
to ponder, and lo and behold, it found e6 itself. :)
Crafty liked Qb6 at shallow depths, but dropped it at depth = 7 and never came
back (searching for a black move to ponder). After Qb6 we were out of book and
this is what we were thinking:
13-> 37.97 0.44 7. Nc3 Qxb2 8. Nge2 a6 9. a3 Qb6 10.
O-O Qd8 11. Qc2 e6 12. Rfc1 Bd6 13.

Rather than Qxb2, Yace played e6 now and we saw this immediately:
