Effective stack is 5.60 -- hero dealt a2 offsuit in the bb, playing 5 handed

UTG+1 limps
SB calls
Hero raise to 0.40
UTG+1(villain) & SB call

flop 3cAc8d
sb check, hero cbet 0.49
villain raises to 0.98
SB fold
hero call

given that he limp called pre-flop, i think he could have many suited combo draws such as 24c, 45c, 67c etc.. a3, a8, pocket 3s, pocket 8s.

I decide to call since I'm ahead of a lot of his combo draws and the price is good to continue

turn 7s
hero check, villain 1.89
hero calls

Definitely a tough spot and folding is a decent option, but I think he'd continue to bet with his lower combo draws as well as the combo draws the connect with the 7 (56c, 910c). He'll also continue with any of his two pairs or sets to try to charge a flush draw. We can eliminate a few draws such as 67c as I think he'd check this back now that he has some showdown value.

Given that we're ahead of all of his draws, and we have a blocker to some of his two pairs my plan is to call and try to get to show down cheaply on a brick. If a club or low card comes in, we can potentially jam the river (villain only has about 2.80 effective after turn) and get some of his two pairs to fold.

river 2c
hero bets 2.80 to put UTG all in

We make two pair, however I don't think that changes a lot in this hand -- with the 2c we're pretty much crushed by 100% of his range at this point. Given that, I think our best option is to turn our hand into a bluff and represent the flush hoping we can get his two pairs to fold. I bet enough to put him all in...thoughts?
