BTN is a bad/spewy reg
SB appears to be a winning reg on the looser/aggressive side. 28/22 iirc. We have no history.

Not sure what this donk bet means. Perhaps he is trying to induce a raise with a strong hand, or betting with a draw to see a turn card for cheap.

I don't always have 33/66 here. Maybe I have 20-30% of those combos. I always have TT. I also have many suited clubs or big broadways with 1 or 2 clubs in them which will raise his donk bet some % of the time.

Maybe with AA no club I should have raised flop? As played I decided to just pot control and see the turn since no real bad cards other than a club could come.

Now is where the hand starts to get tricky. I rarely see this line as a bluff. If he is bluffing it must be some type of combo draw like A6cc, A5cc, or A4cc or maybe something like 98cc/87cc now trying to rep the 75s.

More likely his hand is something like 33/66 or 64s that's now trying to get money in the pot since my range is capped to basically overpairs.

I'm not sure if I can fold yet though. There are still a lot of draws on the board and he could be taking advantage of my flop call.

So all his flushes got there in addition to the hands that were already beating me on the turn that are still beating me on the river.

Having a hard time imagining what I can call here with other than a flush. If the river were say, the 4h, I think I could hero call him with AA no club.
