Answer 1

If we bet here, we are doing it as a bluff. Worse hands will fold. With that in mind, what better hands can we fold out with a bet? Perhaps some Ax, but not necessarily. Therefore, we should check.

Now, how about if he bets? Since we have no reads, I will assume he is playing straight-forward and will never double float us. What hands will bluff? There are no missed draws in his range, and worse hands that have gotten this far will be seeking a show-down. Therefore, we can conclude that he is only betting with better on the river.

In short, I would check/fold this river.

Answer 2

With no draws on the board except gutshots, you're probably not going to be ahead here. He will likely call the river since he called the turn (if he had you beat), so betting is probably not a great move. I would check and fold to a reasonable bet.

Answer 3

Checkfolding here is amazingly bad, why do you even bet the turn if you are going to fold to a river that changed nothing?

Put in a blocking bet.

Answer 4

With only a few bluffs and many, many value combinations in villains range, check-folding is usually the best choice.

Given that there aren't any trips or flushes available, nor many draws prior to the river, the opponents range is heavily weighted towards value hands. AJ, slowplayed sets like 22, TT, or a semi-float with 66 that came good at the turn are possible. That's very dependant on gameflow, and our image. If we bet here and get raised we are almost certainly beat assuming our actions haven't been too aggressive or bluff heavy.

K⋄Q⋄ and K⋄J⋄ are possible but unlikely. K⋄Q⋄ wants to showdown and we lose to the K⋄J⋄ straight anyway. Q⋄J⋄ and Tx want to showdown more than they want to bluff.

If we do happen to have 2-Pair or better at this point, if your opponent is capable turning weak made hands into bluffs (e.g. He has pairs) or gutshots/turned flush draws that missed, sometimes check-raising is a good option to create even greater +EV situations in the future, and deter your opponent from bluffing at too many rivers.
