50NL, KQs deeeeeep

I have only 40 hands on villain - not enough for meaningful stats - but fwiw he's playing roughly 24/10. He has already flatted my raises IP a couple of times, and this is the second time he has 3bet IP. He has shown an ability to fold and I haven't seen anything overly spewy post-flop.

So preflop I put him on probably JJ+/AK/AQ, and I thought that although a lot of that range dominates me, it would be worth another $3.75 to see if I could flop a flush or straight. In a 3bet pot with SB coming along as well, I had implied odds out the wazoo. So I figure I'll call, and if I don't get a flush or straight, or a draw to one, I'm gone.

So I flops an open-ender and a backdoor flush draw. The cbet doesn't tell me anything - I think he cbets with his whole range here. I think he either has an overpair, a set or a gutshot, so my draw is likely to be good if I hit and I am getting odds to call.

But if I'm right about his range then with all the blockers in my hand and on the board, he has AK/AQ more than 50% of the time, and I think he probably auto-folds those hands to a raise here. Even if I give him the worst possible range for me here - TT+/AK - he still has AK about a third of the time, which is a good amount of FE. So my thinking was that I can credibly rep JJ/TT/44 and take down a $33 pot a third of the time, and the rest of the time I still have north of 30% equity in a $180 pot. Seemed like a good spot for a semi-bluff.

I could have raised smaller, but I thought that any raise is pot-committing, and if I shove I might be more likely to get a fold out of something like QQ. In retrospect, without extra fold equity, risking this much could be a pretty high price to pay for the equity I have (on my maths its pretty marginal).

Is this pure spew? If so, how should I have played it?

preflop call is pretty spewtastic even with an overcaller.

probably a fold pre
I would flat the flop this deep and I'm not even going broke on K or Q turn

This man is not looking to fold post flop. Look at his betsize, look at the shortstack, look at the board.

Fold preflop too.

BTN most likely has a wider raising range than AQ/JJ+ if he has already 3bet twice before this hand, in a 40 hand sample.

BTN's flop cbet definitely tells you something... there is a shortstack he just willingly committed himself against in a 3way 3bet pot. he might do this with AK some of the time, but generally he would check behind worse than a pair of Jacks in this situation. you don't have much fold equity versus his cbet range.

if the SB isn't a complete moron, his coldcall range IS something like JJ+. against his range your hand is ruined by reverse implied odds! when he has JJ and you flop a K/Q, he isn't putting more money in. when he has AA and you flop a K/Q, ur toast.

however if the SB is a complete moron or something close to that, 4betting preflop is certainly superior to calling.

-you can get all in versus the SB with decent equity.
-your 4bet will be percieved as being stronger than usual by BTN, because SB is in the pot. he won't continue with worse than QQ+/AK, and he folds QQ/AK at least some of the time. you have at least 66% fold equity vs. BTN, maybe even as high as 80%.
