89s TP and Combo draw in a 3 bet pot

well thats a fine line imo tho i will prolly bet the flop most of the times since it makes no sense for him to 3bet then check flop i guess he s slowplaying QQ+ like a typical donk and its like a coinflip vs overpair so get it in
on turn as played u dont really have another option than push

im betting the flop and getting it in on the flop

You're in a good shape with your cards and if you like playing for stacks calling 3bets with SC's then you may as well get it in as you're not going to get much better spots. I think despite his low 3bet % you say he defends his BB to steal 50% then he could just be defending his SB to your steal and doing this with a much wider range - a lot of which you are ahead of. I don't agree when you say "I figure I'm flipping against overpairs and killing air, so I shove while I still have FE against a weaker overpair". As I don't think you're going to get too many overpairs to fold with this line but you do have good equity against top 4% of hands and some equity against overpairs (you're only 37:63 Vs TT+).

Bottom line is I like it but maybe not for exactly the same reasoning as you.

If you flat turn, you miss your draws and he bets out then you have to fold imo. If he checks then I would probably check behind but I do miss value too often so maybe I am wrong there. Shoving turn is better imo.

I prefer your line to bet flop call overpair shove as that is a complete coin flip but maybe I'm just a nit.....

bet flop and try to get it in when you're 50%, not on the turn when you're less than 50%.

I'd call turn and call/shove all rivers except maybe an ace. For the reason that he is never folding an overpair on the turn, you might as well get the same money in on the river in a way which allows more weaker hands to stack off to you (bluffs, other draws), since they aren't often calling this shove. He's almost always stacking off with an overpair when you hit one of your million outs anyway.

That's the weirdest thing.. I ran the calcs against kings and could have sworn I got 52% equity on the turn, but as people mentioned its closer to 40%. Whoops. Thanks for the advice, all.
