Grunch.

Hand 2: Given your read, I think that hand 1 is fine. A 3-bet on the flop or raise on the turn is going to push this guy out of the pot if we're ahead. If we're behind, then check-calling loses the least (with the exception of your river raise). I suppose that you might also consider raising the turn for a "free" river card, and then bet the river if its a brick. (Non-A, non straight-completing card). Do you have a read on whether this guy will push a draw?

Hand 2: BB's call makes this hand easy to get away from, IMHO.
