villain is a 31/18/11 semi-lag reg that I have been battling with all day. I don't think he balances his ranges well, ie his x/c ranges are usually not nut hands that have equity against my range, and his donk leads on streets are usually backdoor strength. He's not a bad player or hand reader, and I'm sure he wins in these games. he wins 40% WSF and has SD stats of 28/59. So he's not bluff catching, betting thin, or turning a lot of SD into bluffs.

For the session he probably sees me as a 28/17/6 player for 6 handed, but he's noticed by now that I'm 3betting very very wide when deep stacked against other regs. At least 3-4 times now (including against him) he's seem me pot 3bet IP with a single suited rundown type of hand against a reg with 300bbs or more. He also knows I'm capable of bluffing and raising multiple streets with more than blockers.

pf is obviously loose. by the HJ opens way too wide in this spot (like 24%) and we're so deep I can stand a 4bet and play against him. Plus I don't think he plays terrifically postflop.

when the SB pot 4bets (after a very short tank) I make sure to tank a little before calling to slightly disguise my range.

should I fold initially? is there any reason to fold to the 4bet? fwiw I need a new HUD (if anyone has suggestions) because the only 4bet stat I can find for him is a 4bet after initially raising. So I can't exactly give a range estimate here. But I'd guess its huge rundowns, AAxxds, AAKxss, AKKxds, and the like. I don't think he's going to have too much junk in this range.

the flop hit and I know that I have a huge range domination advantage. my first thought was that I need to barrel off almost always on this lockdown board against a range that is probably capped at A2 for him. I think there is a pretty good chance he might cbet a set, but even those might check call.

I do have the one 7 blocker.

turn is great because it prevents bd flush draws from having incentive to call down. My sizing is to set up a river jam.

as the river is happening I stack him on another table in a 3bet pot OOP when he called it off with two outs on the turn.

river is not my favorite card, because if he ever has a 3-5 to go with his AAxx he might call here. Also some other gutters might have gotten there (6x). I tank for just a second before shoving the rest in.
