River bet was supposed to be a standard value bet. I didn't think he would ever raise me.
My top pair doesn't seem to be good?! Can't be a busted flush draw, so I only beat A with weaker kicker or a bluff.

Thanks for your thoughts,
guess

I think he flopped a monster, like fours full and loved that turn card as it is likely to have hit you. I can't see him doing this with a hand you beat

There's no way you should call this. You need to be good at least 1/2 the time - unless villian is massively over aggressive, you are not going to be good anywhere near that.

I think it would be easier to put him on a range if you had bet more on the turn. Pot the turn, and if he calls or raises then you know that you're probably behind.
