Hand 1: Bet less on the flop. You could probably scale it as low as 2.25. Also allows for future bluffs to be smaller if you think is capable of calling one street with a King here.
Hand 2: Aside from betting less on this flop, opponent has a 25 dollar stack. If he calls, pot will be 14.50 and he'll have 19 behind. If you bet less, you increase the range of hands he'll call for value and you could have 12.5 in the pot and him 20 behind. 7 turn, 13 river is an ez game.
Hand 3: This one was fine because he'll never fold a jack and probably call one with 55-TT. But checking behind would be neat. I'd bet 3 on any turn.
Hand 4: Initially, I though check/fold flop. With the flush draw, you can try get a little value out of your opponent and maybe he'll peel with something. However, I would turn 44 into a bluff on this river. Board just runs out really bad for a lot of hands op can have that beat you.
Hand 5: Just fold preflop. I don't really understand this play at all. Trying to iso MP1 by giving him good odds because UTG always calls?
Hand 6: Pretty standard
Hand 7: Already said I would bet less. Probably 4. Checking behind would be keen even though it's 3 ways. Wonder what I'd do on a 4/9 turn a Q/A/T and a K/blank.
Hand 8: This hand is pretty bad. BB is going to call with everything. Then you get the perfect flop to cbet and a good one to check/raise. It makes sense if BB is a hyper-nit.
Hand 9: I would raise pre for value and this flop is just too delicious not to bet. Lots of value declined.
Hand 10: You have to c/f this flop. So many hands will call you and not fold to turn barrels (which I don't know you're capable of pulling off with your image). Pairs/draws, pure draws, pairs. Every hand folding is worse than yours except 22-66, which is a tiny fraction of his hands.
Hand 11: I think this is a clear turn b/f. Get value.
