2 Turn Raises

[DaveB]

First hand is from a 6/12 loose passive live game. 5 or 6 players limp, I complete AsJd in the SB, 7 or 8 players for 1 bet. Flop is AQT with 2 clubs. I check, checks to MP2 who bets, CO calls, button folds, I raise, MP1 cold calls (he has played typical-passive to this point.), MP2 calls, CO folds. Turn is Ts (3 players). I bet, now MP1 raises. I?

Second hand is from a live 10/20 game. UTG, UTG+1, UTG+2 limp, fishy SB calls, I check in the BB with QcTc. Flop is Ts7s7h. SB bets, I call, UTG folds, other 2 call. Turn is an offsuit 8. SB checks, I bet, UTG+1 folds and UTG+2 raises. He seems fairly loose preflop and moderately tricky/agro postflop. SB folds, I?
