I think that my mistake here was not raising enough PF. I think around 28 BB would have been ideal, Any bigger would leave me with much less than a pot sized bet after the flop vs one caller, what do you think?

I am interested also in what you make of Villain's play. I think that his call of the 3bet PF was too loose, especially with players behind, would you agree?

On the flop however, vs my AK (which is rather face up I would say) his hand has roughly 36% equity with the BDFD also. He is getting 2:1 so needs just 33% does that mean he should be calling here every time? I mean obviously if he's calling PF with that hand then he's definitely calling on that flop but is it okay?

Thanks

River: (225.4 BB, 2 players) Q

I'd rip it pre-flop provided that MP+1 isn't a massive nit. There's 21bb of dead money in there and you've a good shoving hand.

Ok thanks I will take that on board! Would you mind commenting on villain's postflop play here also please
