Very loose player opens BTN 2bb, I defend BB with K4s,
Flop: 235 rainbow, straight draw, I check. Opponent makes pot size bet. That means nothing, I know this opp can't adjust his bet sizes properly. I don't have enough outs for calling, so I make reraise (how about my sizing, should I reraise bigger oop?). Opponent calls. Board pairs, I check, opponent bets small, I can call.

I get my out on River, straight. I don't know is my opponent capable to bluff. He called my flop reraise, he bet on the Turn, so I think he has something, I think it will be the best to bet. Question is, how much should I bet to make him to call? I made little bit smaller than half pot, he folded.

What do you think?
