given that the player who called you (MP2) is somewhat short stacked and the board is coordinated, you can't slow play the flop. I would bet the flop, about 1/3 of what MP2 has left (200).

The only time you'd ever check this flop is if you're sure he'd bet. Since you probably can't have this good a read on someone, make a pot sized bet. Too many draws can hurt you here. That being said, I'm calling the river here, since you showed weakness on the flop and river.

I think you have to bet the flop here with both the flush and straight draw possibilities on board. Feels to me like you are in a lot of trouble on the river if this guy is any kind of player. He limped coming in and called your raise, suggesting a hand like a small pair or suited connectors, or maybe something like A-x suited or K-x suited, or KQo, KJo, JQs or off, J-10s or off. If he has an overpair, top pair, two pair or trips he probably bets the flop, so let's eliminate 99, TT, JJ, QQ, KK, 55, 88, 66, 6-8s. When he calls the turn, either the ten helped him or he has a flush or a straight draw with a pair. He should not have called with only a straight draw or only a flush draw. When he moves in on the river instead of just checking the hand down, he's there. I think he has 67s, 77, or 10,9s, maybe K-7d or Q-Jd and you are beat. Dont know if I could have layed it down though.
