Here's a big hand I lost. This is at a .10 NL table.

I'm in BB spot, get dealt JTo and check into the pot. Two CPs fold.

9h 7d Jd hits flop.

UTG and UTG+1 both check. I throw a bet of 10 cents. Both players call.

Js hits turn.

UTG and UTG+1 both check.

I throw a bet of .10 (I realize how STUPID this was, but I thought looking at this flop and both players just checked that with trip jacks I could up the pot to win some more money.)

UTG and UTG+1 call.

8s hits the river giving me a 7 to jack straight.

UTG and UTG+1 both check.

I throw a bet of .40, UTG goes allin with 8.60, UTG+1 raises to go allin with $9.70 and I.... called going allin with my $8.75.

UTG had QT and hit a straight 8 to queen taking the $26.55 pot.
(UTG+1 had Ts6s and matched my hand).

My question is, based on these two players actions from preflop to river, is it obvious UTG had QT?
