Justified caution OOP? 5-10 deepish

[Wardfish]

Just looking for some input on how I played these 2 hands. Both were OOP and played very cautiously. I'm just looking for constructive comments to help me play these hands better.

In hand #1, villain had made the min-raise on the flop previously with a weak hand (he folded to a 3-bet shove) and a monster (trips). He has also previously called my continuation bet with an unimproved PP, then checked behind on the turn &amp; river.

In hand #2, villain was quite loose and very aggressive.
