Hi mrbeast,
Preflop: What do we know about our opponent here?
Do we expect this 3-bet to be for value? What do we plan to do versus a 4-bet?
Postflop: As played we would need to know something about the opponent, did you have any info? If not it's a fold.
However, do you see a lot of value in a bet on that flop, in a 3-bet pot (what do you expect his range to be)?
