2/4 mid pair

[Bob T.]

This is a tricky situation. If your opponent was more aggressive, there would be a good reason to check behind. He might checkraise semibluff, and put you to a decision. That same opponent would be more likely to bluff a missed river, so by checking behind, you probably win one bet, and don't risk losing the pot.

With a slightly passive opponent (with limited hands, I know but it is all we have to go on) I think I like betting the turn, and checking behind on the river.
