pick up a value bet or check the river.

[Mikey]

Here is a common situation, I'm sure most of us face.

Let say you have a pair of 9's and raise in mid postion after everyone folds to you. The button, the SB, BB call.

The flop comes Q 8 5 r.

both blinds check, you bet, the button drops, the SB drops the BB calls.

Turn is an A.

He checks, you bet. he calls.

River is A, K, Q, J, T, 8, 7, 6, 4, 3, 2.

He checks.

Should you bet again to pick up an extra value bet or check it on through...and hope your hand wins in a showdown. Which cards falling would you want to river value bet and which ones would you check it on through.
