Please comment on bet sizes (too much/too little) and if it was a good place/time to steal. Anyone paying attention/having stats on me know I'm tight. All three hands were on air.

Hand 1: Both opponents VPIP over 40%, SB passive, MP1 aggresive. Was this to risky or believable trips since I lead out on flop?

Hand 3: SB Loose/Aggresive, No read on MP2. Weak bets encouraged me here, figured I could get it with the scare card for the straight. I figured no one likely on a straight draw with the high preflop raising.
