The villain in this hand has shown the capability to be bluffing in a variety of spots with a VPIP of 40%, PFR 12%, 3bet 8% over a very small sample of 60 hands. So, I went into this hand expecting to do some inducing and bluff-catching.

I've been experimenting with different size bets to isolate. It seems like 4 bb is about the minimum to have any kind of fold equity. I've gone as high as 8 bb with stronger hands. I haven't noticed opponents making any adjustments at this point.

I don't think that this raise has reduced the villain's range much as they have been continuing very widely to this size.

They haven't 4-bet much so I don't think we can eliminate the strongest part of their range.

So, I follow through here with a c-bet. I've been almost range c-betting in a lot of spots lately for a small size. When the opponent plays back, I feel confident in calling. I've seen this opponent check-raise the flop and then check-fold the turn more than once already. I'd almost be more concerned with a call from this opponent.

I wonder about this check behind. I thought that letting the villain bluff the river was reasonable but maybe not great with 99. There is a world where the opponent bluffed a 6 and is trapping now but I thought that there were quite a few pocket pairs, flush draws, and random 1-club hands the opponent would bluff with on the flop that could go for it on the river.

I don't have a strong read on if the opponent always fast plays their value after the flop check-raise.

I really didn't like seeing this size with this river card. 45 gets there which isn't ideal, but there are still a lot of bluffing candidates with missed flush draws, and any 1-club hands that they could go for a bluff with.

I didn't have a strong bet-sizing tell for this opponent which really pushed me toward a fold. I would have been pretty happy to call anything pot-size and below but this just always seems strong.

So I guess for value the opponent can have some combos of T6, 36, 62, some slow-played sets TT, 33, 66, 6x, some combos of the straight with 45o and 22 that got there on the river. I don't necessarily think the opponent has all of these combos given the action so far. Some of them will fold pre-flop, some of them will be checked back on the flop, and some will be value bet on the turn. But when the opponent bets 5/3 pot he has to be bluffing more than 3/8 or 37.5% of the time for this to be a profitable call. That is starting to feel a little optimistic at this point.
