H1 i think is fairly well played IMO.. might think about raising the flop to punish any drawing hands..

H2 im not really sure lol... theres a lot of limping/checks so 96 or flush draws are in play. i dont think its a mistake at all to lay this down.

H3.. i dont mind calling that flop cause i think its not in UTG+1 range, but i deffinately come over the top on the turn. IMO your in front and want to build the pot, maybe .50c? or are we keeping worse hands in the pot by calling again?? not sure about that bit..
