I was playing very tight the player behind me was in many hands. I finally got what I consider a decent hand( let me know is it too wide when it’s not suited in this position?)i 3-bet light to check UTG’s strength and also try to push other players out of the pot. I did’nt like that BU called behind and I was in the middle now Ichecked the flop because I thought UTGs range could consist of a many aces.(also should I not try to c-bet bluff 2 players like this?i read somewhere that with a flop of 2 other players they only miss the flop 1/3 the time) AJ+ maybe AA-TT . BU range fairly wide he was playing many hands and was behind me so I played tighter. He could hold JTs+,ATs+,AQs-J9s and maybe TT-88 I thought with higher pairs he would 4-bet a light 3-bet? Turn comes 10s I make a gut shot and because they both checked the flop they seem on the weaker side so I bet. When BU calls me that’s where I got confused with his range could he do this with an Ax on a wet board? Would 9,T or TT have been a re-raise by villain ? He calls and River makes my straight . What does Villain have here ? I almost folded to the backdoor flush I swear it was 50/50
