Hi, HG, thanks for the responses. I grabbed this part of your last comment:
"Being allowed to do two quiet moves in a row (which is what happens when
the opponent loses 1 tempo) makes it more likely you will win that race."
I would argue this presupposes that the pieces are mobile enough to need
only 1 turn to make the key attack. Hmm, guess that's the same argument I
made last comment in a different guise, or at least from the other
direction. The small board certainly plays into it.
Nice aside, Derek!
