BB struck me as fairly solid and thinking. I've stolen from the BTN 2 times in the last 7 orbits due to excessive activity from everyone else.

What range do you put your typical $10 MTT player on in this situation?

What range do you put me on when I a.) flat-call BB's bet and when I b.) shove over BB's bet?

Lastly, what's your action and why?
