Took TCB significantly longer to see Bxd5, but it decided that it wasn't such a
good move after a while.  I'd be interested in seeing if Rebel Century would
have also moved on to a different move if it had been given some more time.

I don't understand the Bxb5 move very well, it looks like a move I'd make in a
blitz game to confuse my opponent and make him think I understood the position
better than I did.  But I like it significantly more than the move that TCB went
with after it gave up on Bxb5, then it moved on to 1.a4, that move I could never
make.
