J965ds 3b ip

Loosy-goosy 3bet here against MP. Hand is doublesuited and somewhat connected, but not great. As a standard I would fold, but I guess it's not terrible to mix up your play little. And if I'm gonna play this 3betting would be only choice from CO, definitely don't want to flat this.

Yeah I would check-back this flop. I think it hits both of your ranges quite well, you'll have to invest a big bet and get folds mainly from totally missed hands by villain. Unless he has Q-hi FD you end up folding good equity here against check-raise, which is very unfortunate. You've somewhat hidden FD when checking, you have backdoor FD and some SDV with J and chance to hit trips ie. You definitely have a piece of this board and can defend your check-back OTT if villain stabs unless a very bad card comes and villain just bombs it.

So basically he always has QT or QQdd, can you call against that range? How deep do you need to be to start the hand in order to call this raise profitably?

I mean, if the board pairs or brings a ♦ he can't really continue with his straight? Even though now he has only 45$ behind but very little equity vs hero's bet/calling range on those turns.

Can't comment on the 3b much more than that it seems too loose. I haven't really figured out static 3bet ranges IP...
