Hand 2. Call me a tight full-ring player but...

If I'm villain, facing a 12xBB reraise, my AJ is mucked pre-flop. My guess is his calling range here is TT+, AK. I'd probably re-raise AA or KK, but not everybody would. If we are getting 2:1, it could be be a thin call. But I'd fold and keep 2/3 of my stack.
