1/2 Putting myself in sticky situations

[bottomset]

I haven't played with villian before, but did take a pot off him with a float(he limp/called OOP and lead a 335board I called with KQs bdfd and he c/f turn), he's only been at the table ~10hands

I feel I've been cbetting too much lately, so decided I to just check the flop here with a modest draw that I'd rather not get c/r'd off of

the turn is a brick, but he hasn't shown any interest, so I take a stab at it now(this may be a leak as its kind of tough to rep much here)

on the river I hit a pair and decide to put a valuebet in, his c/r surprised me, there are a few draws that missed anyone like looking him up here?
