1st hand - in the heat of the battle i probably overcall, though folding might be correct. everything got there. i feel like it's a very close decision and so i err on the side of calling in pots of this size. the psychological effect of folding and then seeing that you had the best hand must be considered here.

2nd hand - i think a river call is much clearer here, b/c you almost surely have the bb beat and the sb could be betting a weaker ace. i think raising the turn on hand 2 has merit, also.
