UTG is playing pretty tight preflop but going apeship postflop in very minimal hands on him, hence my flat pre. BU is a tag who plays 37/25 over my 2.5k sample. BB is relatively unknown as I only have 30 hands on him but he's playing 20/20 with 10% 3bet and no steal%. I got completely lost in this hand and wanted to 4bet jam but we are a little deep and I think it's rare to see an unknown 50NLer squeeze lightly in this spot. On the flop, UTG insta shoves when checked to. I definitely think he can be the type to slowplay AA or KK in this spot, but can probably have like TT/JJ as well. I was afraid of what was also behind me. Can I fold earlier? Should I just jam preflop? Am I gay?
