I'd guess he's probably only opening about 10% from EP and calling 3bets with half of that, and also could probably take out AA, KK because he'd probably shove?
So taht leaves us with TT, JJ, QQ, AQos+ and maybe a few a few suited connectors say T9s+
Against that your equity on the flop is 89%
He has:
8.7% OESD
4% flush draw
With his fold to cbet at 33% odds are he's going to call that cbet with pretty much his entire range.
Equity on Turn is 76%
He has:
10% chance of made straight
7.5% chance of QQ
5% flushdraw
On the Turn he's more than likely going to start shutting down everything less than top pair or midpair plus draws.
That puts your Equity on the River at 75%
He has:
4.35% chance of made flush
10.4% of made straight
10.4% of QQ
10.4% of two pair
42% of top pair
21% of JJ
Now I guess you have to work out what he's going to fold to a bet. I think it's safe to say he's going allin with the top 3 about 25% of the time. Teh rest I don't know.
I suppose you could make a small bet that he'd call with his bad stuff and then raise with his top 25% and then fold if he shoves.
Pls keep in mind I only started learning poker recently and don't know what I'm on about!
