posting it here since no one really looks at the HU thread.

villain played a little straight forward at the beginning of the match, folding a lot from the blinds and folding a lot of buttons.
then he started adjusting by 3-betting some of my button raises and started calling some of my 3bets. but no 3bet pots went to show down yet at this point in the match, and i still think a polarizing my 3 bets is still good at this point cos he hasn't really called much yet vs my 3bets.

so in this hand when he calls my flop cbet, he could have over cards, A-hi and small-medium pocket pairs. then we turn an open ended SD what do you think is the best line here? bet this turn $12 to push him off A-hi and over cards? or should i bet more like $14?

I'd bet/fold 15 and shove any Q/K/A/5 river and c/fold the rest.

Fold pre.
