[SH] NL50 AJo 4bet pot

I think Pleno will tell you to flat the 3bet

I would 4bet too, and I would do that exact size.

Post flop I really don't know. I can see him flat your 4bet with a lot of random hands.

the small cbet supplied a good chance for him to bluff with 16 for 44.5，it doesnt need to work a lot to get a +ev
i rather check raise shove than betting small here

hihi.

So we should be 4bet bluffing vs this guy, cool. But why choose such a good hand? Especially as he will 3bet bluff Ax hands we dominate a lot of his range.

I'd choose k9, jq, kj kind of hands to 4bet bluff and flat AJ here that plays well and dominates his range.

Post flop is very "feely" you need to be in the dynamics of the game to decide, its a nonsensicle line so going all in will never be terrible, but if in game you get the feeling its a value line then its also perfectly fine to fold.

Is it best to CB?

I think cbetting in 4bet pots happens quite often and should be profitable given the risk/reward ratio we have. There's also a lot of room for sizings but you have to strongly consider your own range there and KNOW that if you check you have to check/call(or shove) some hands and not always check/fold.

I agree with Patrick about preflop though. Maaaaybe because it's offsuit you can argue more than usually towards a 4bet but it dominates many of his hands so calling give you implied odds on J and A high boards.
