Oh wow that's a hard spot than with no previous information on your opponent, I might have laid the hand down because of the pressure he was applying but it is a hard fold with no information. You couldn't really do much here accept believe him because of the strong strong betting pattern, he played his set exactly how I would have. He got lucky no cards came out to scare you, I might have folded the turn though, because in my opinion when you call turn you almost always have to call river if it seems safe enough, He could have been playing AA, KK, or a better jack and in this case unfortunately a well hidden monster. Hard spot in all though, and I probably lay down turn with QJ thinking I am beat here most the time. You were a non-believer because it was your first hand and unfortunately you were wrong about said player, pretty unlucky first go, but sometimes big bets mean your crushed.
