tstone 3-6 JTos CO

[man]

wonderful LP game. couldn't have asked for better conditions. UTG is a tight tending-towards passive player. UTG+1 has played in every pot since I sat down five hands ago. he folds rarely and calls often.

I get JTos in CO. UTG calls, UTG+1 calls, fold to me, I call (OK?), fold to BB.

flop comes QT7r. (4.33 SB)
BB checks, UTG bets, UTG+1 calls, I call (?), BB folds.

turn QT7 (Aos) (3.6 BB)
UTG checks, UTG+1 checks, I bet, UTG folds, UTG+1 calls.

river QT7 (Aos) (2os) (5.6 BB)
UTG+1 checks, I check.

fishy or prudent?
