If your read is that SB is a good player, then this hand is weird.

He cold called your 3bet preflop, so I feel like I'd like to narrow his range to JJ+, AQ and AK sometimes. I doubt 44 calls here if he's good and maybe sometimes he has 99 but that should be discounted too. Its not even deep.

Given that you bet this flop into so many ppl, I'd say that he would probably even find a fold with QQ/KK here if thats what he had.

I feel like he has AQ,AK,AA here a big percentage of the time. I'd bet each street here trying to value town AQ, $14 turn and shove riv. If I get raised... I might throw up.
