2)The call preflop was again ok because it gets more value out of hands such as AK,AQ, and lower pokcet pairs. What was the reason for checking this flop? And im not sure i like the idea of moving in over a TIGHT player because the likely hood of him caling with a worse hand here is not that great. Im letting himself commit himself on turn and moving in here. Moving in on turn with villan commited will get worse hands to call.

3)Your flop play is fine, with so many people in the pot and with straight/flush draws possible it's the right play. On the turn just keep building the pot, no point checking if other players are passive and will take free card with there draws. Then if you get callers block river if scare card, and value bet if not.
