UTG raises to $6, 1 fold, MP1 calls $6, MP3 calls $6, 2 folds, Hero calls $5, BB calls $4.
Flop: ($30) 8



Hero checks, BB checks, UTG bets $18, MP1 raises to $36, MP3 calls $36, Hero ???
I'm pretty sure UTG is going to push when it comes back to him and MP1 looks like a set. Thus no fold equity by pushing first. Standard fold?
