Hand 1: I'll call pre-flop against a nit hoping to flop big and stack him. However, here AA and AK would stack you most of the time if opp bets flop with the A and you raise.
I prefer call and see if he keeps barriling the turn, then I would give up.

Hand 2: Well played.

Hand 3: I would raise/all-in flop with 14 outs.

Hand 4: I might fold the flop. You are given about 2-1 to call the push and it means opps needs to have ATo or less at least 33% of the time. Without reads I don't think he does ...

Hand 5: I wouldn't bet near pot on 3bet flops. About $25 would do the job.

Hand 6: With an opp with 7.5 AF on flop I push it also.
