A high vs fish
 

This time you got AK

You raise and uberfish calls.

Flop shows a possible draw and that all. By the river the draw didnt materialize and its all bricks.

River comes either fish checks or you act 1st.

There are some fish that will call a river bet. Some that will fold to a tiver bet on a scary overcard board like QJT.

Or you have AQ and the board is KJx. Thats actually more appropriate.

Is it worth betting that river to see if the fish folds?

Or would it be best just to watch others when they bet the river if the fish folds?

Re: A high vs fish
 

The problem with betting here is that the fish is not likely to fold a hand that is better than yours. That's why they're a fish.
