White(1): quit
execution complete.
So it's Qh2 up to ply 10, then Bg5 at ply ten, and then e5 at ply 12.
We could think of them as all good moves, but by ages.
Qh2 is the junior move.
Bg5 is the club player.
e5 is the master.
Bf8 is the GM move.
I think I will try some other programs to see what they will do also.
This position is especially interesting because new depths show genunitely
better moves, and none of them is trivial except the first.
