Villain is a reg, but we don't have much history. Only read I have to date is that he 3bets liberally.

90bb effective
Villain opens CO to 3.5bb
Hero flats KdKcJd3s on the button

Flop KsQd2s (8.5bb)
Here pots, villian calls

Turn Tc (25.5bb)
Villian checks
Hero?

AJ and J9 wraps both got there. But there are likely a lot of flush draws in his range too, along with turned two pair + gutter. Should be a simple maths problem, but without reads I'm finding it difficult to construct a useful range to assign villain.

Pot / call, bet / fold, check and evaluate?

Thanks,
