River chop?

[Captain R]

Garden City 20-40:

UTG, fairly weak-tight player open-raises. Super-fishy lady calls, I 3-bet A[img]/images/graemlins/diamond.gif[/img]K[img]/images/graemlins/club.gif[/img] OTB, all fold and UTG/fish call.

Flop is K[img]/images/graemlins/diamond.gif[/img]Q[img]/images/graemlins/diamond.gif[/img]5[img]/images/graemlins/heart.gif[/img]. I can tell UTG has a good piece of this, he checks, fish bets. I just call because I don't have a good feeling about UTG and I don't understand fishy lady well enough to know what she's donking. UTG raises, fish/me call.

Turn is 7[img]/images/graemlins/heart.gif[/img]. UTG bets confidently, fish calls, I call.

River T[img]/images/graemlins/heart.gif[/img]. UTG checks, fish checks.

Easy bet? I know if UTG calls I have at best a chop.
