hand 1 - i bet more on the flop ($1.40)because there are lots of hands we get called with which we beat (weaker queens, tens, straight draws, flush draws, maybe even 77-99) and few believable hands which beat us (TT,QQ+,T2,Q2,QT) and most of that range either gets 3bet (QQ+, maybe TT) or folded (T2,Q2) pre anyway. on the turn i probably bet/fold about $2.80 not expecting to be being bluffed often should we get raised.

hand 2 - i bet a little more on the flop and certainly 3bet shove the minraise and caller. we have 35% equity drawing to the nuts, and are in good shape against any one pair hands, weaker FD's, pair/flush draws, or straight draws. anything really except sets or two pairs (there arent many two pair hand combos really because the pot was raised preflop) we have easily enough equity to get it in with, not to mention the fold equity we get when our opponents fold their 1pair hands.

hand 3 - i probably dont cbet this flop as it doesnt appear to hit our range and we only get value if we fold Ax hands (or middle pairs if a good barreling cards falls on turn). that said, im not very clever at picking good cbet boards unless i have reads. i probably fold on the turn to his stupid bet. cant really see him folding often if try to turn our K high into a bluff.
