This spot sucks. I don't cbet many 3-way pots w/o connecting somehow, although when I do it's usually in position. When I get played back at, I just fold.

I posted on stealing in the BC, and toward the bottom are a bunch of filters I worked on in HEM. You might find the results interesting, but it's only 9k hands - I've been working a lot on stealing.

Upshot? Stealing is profitable BOTH when you get two folds and when you get called. My winrate was actually higher when I was NOT successful stealing, meaning I'm winning a good bit on the flop. I think the key on the flop after having a steal called is not losing the big pot. You can take a stab, but folding is definitely not a big leak if they wanna play back.
