$100PLO Interpoker. I'm on the button with $103 and Kd 7d 9h 8c. I limp after 4 others, SB in, flop is 7 handed. Flop is 8s 2d 6d. Checked to me. This is a tight table and i bet pot of $7 thinking I'll probably take it down. Only the CO calls. He started with $30 and isn't the best player in the world. I haven't seen him show down much so far. Turn is 4d giving me the K high flush. He checks to me with $22 left. I wasn't sure what to go for here (from what I'd seen of him he wasn't necessarily drawing to the flush - he could've had 2 pair or even 1 pair). I decided to bet $10. I think this may have been a naff bet as it committed me to the pot really (as he only had $12 left afterwards). He called this and went all-in on the 8d river. So it was $12 to me in a $40 pot. What do you do? How would you have played the rest of the hand?
