So, two pretty basic spots here. 

Assume 6h 100bb stacks.

1)

UTG Fish Limp, MP raise 4.5x, I call CO 9944hhss 3 folds limper calls

Flop Tc9c8d(15)

UTG checks, PFR checks, I?

2)

I open CO 3x KKT7cchh, btn calls, BB calls

Flop AJ7rh(9.5)

BB checks, I?

I assume the first is a pretty clear bet, mostly for protection but some value.  I'd think it's one of those hands we'd want in our bet flop bet turn check down river ranges. 

Second I think is a bit awkward.  On one hand, betting doesn't really get value from a ton of hands.  It does however protect our hand.  Not sure if this one plays better as a x/ca or a bet flop shut down when called.  If I do decide to have it in my x/ca range, I think I need to be leading turns, specifically, Q,T,9,8.

Thoughts?
