Two question about this hand:

i) Would you bet the turn (how much)?
ii) After not betting the turn, how much do you like my semi bluff bet on the river? Is it big enough?

Checking the turn and then bluffing the river is OK here since you're OOP, but if you're going to bluff, I'd bet at least 3/4 of the pot. That $20 bet is going to get looked up by a pretty wide range--I'd put in a call with as little as one pair.

However, I'd tend to muck this on the flop.
