Villain is unknown.I have 10 hands and no significant idea.
Flop is not a question.
Turn: there is only QTdd left, so 1 combo of 2p, assuming most don`t flat QTo, I am happy betting. I think sets will reveal themselves here, often on flop too.
River: I have the Ac. I think 87cc 98cc is raised before river some nonzero amount of the time, 43xx got there, KQcc , 54cc(also raised some on turn?) Some weird AA-KK is possible, if slowplayed the runout is probably not what villain is concerned with.

So only reason to call is if I believe villain miss-played some value I beat. I find it hard to count out bluffs to warrant a call

But I am curious to how I am to weigh the fact that I have Ac. Chime in....:), and betsize river?
