MP checks, Hero ????

I find myself in these situations a lot and no matter what I decide to do, I feel shaky on it; and I don't like indecision in my play. My preflop raise was standard. Villians' stats: Button: 71/29/47 over 35 hands; MP: 64/5/38 over 22 hands. So both have a really large range here. Should I bet and if so, how much?

Definitely check here. With two players in the hand and one having position on you, we would need a much larger stack to be willing to toss out a bet. The success rate of a bet is low and if/when you're called, you are basically relegated to giving up against any aggression.

If you want to bet it should be more of a value bet than anything, which would be small...like around 1/4 pot or so
