Villain stats from the BB.
F: 70%
C: 9%
R: 21%

Not to many reads on villain other than this. We are 7 hands into the session. I played him a month ago but I don't have any notes on him from them because I didn't used to take notes on the PT4 back then.

I'm not going to put up with this wimpy 3bets so I put him to the test and get value out of this wide 21% 3 bet range.

What is the best way to proceed here? Should I attempt to check down? This is another one of those low SPR situations in 4 bet pots that have been troubling me lately.

Not going to say what play I made here...but we need 25% equity to make a call. I don't think we have enough to call here. I'm not sure he would play a K like this. I guess he could be spazzing out with pairs below a K and be betting for protection/value. I don't think we do well enough against this range for a call to be profitable here. We only really beat random spew junk cards he could have but he probably would have mucked those on that dry of a flop once we cbet.

Any help for this spot, specifically the flop cbetting logic? What type of things should I consider when deciding whether to cbet pots in these low SPR situations?

Thanks!
