Villain okay reg. Fish OTB.
Gameplan for this hand?
Cbetting flop would be the easy way out.
Villain shouldn't have too many Ax he wants to value bet. I would assume AJo folds pre. we block AQ. Given that I think we can check/call flop.
I would assume villain bets his weak flush draws on the flop. With KQo I think just betting the flop would be good to make me fold TT type of hand or worse. I think I do have range advantage here big time so villain should not be betting flop very often.
When he bets the turn first thing that comes to mind is T9s but that's just one hand combo. We would need many other bluff combos to make it profitable call. Do we have enough equity to call turn?
If I'm optimistic, villain would bet some KQ combos, Q9s T9s and 9c8c 8c7c.
We could call turn if we think he overbluffs the river, but blocking KQ bluffs is not good in that regards.

Here's what I come up with.
BB 29.92% 29.92% 0.00% QsQc
CO 70.08% 70.08% 0.00% 88, AQs-A8s, T9s, Qd9d, Qh9h, Qs9s, 9c8c, 8c7c, AQo, KsQd, KsQh
