Option 3? Doesn't work very well. You're assuming the opponent doesn't want to threaten the bishop, which means you yank it to a place where it would be safe if the opponent doesn't want to threaten it, but if the opponent clues in, it's then trivial for them to threaten the bishop again (to gain more advantage as you try to defend), which you weren't expecting them to do, because that's not how your search tree was structured. Kasparov would kick hell out of thus-hardwired Deep Blue as soon as he realized what was happening.

It's that whole "see the consequences of the math" thing...
