Tilt, Brilliant, or Boring?

[vmacosta]

Greetings from the very good NoCal live mid-limit games. I had been playing an hour or so and was down a rack when the following hand came up.
UTG (a weak/tight regular, a rarity in these games) raises, UTG+1 calls, 1 MP player calls, cutoff (who is a MAJOR fish, probably something like 75/8/1) calls, SB calls and I call in BB with:
7 [img]/images/graemlins/club.gif[/img] 6 [img]/images/graemlins/club.gif[/img]
Flop comes 7 [img]/images/graemlins/spade.gif[/img] 5 [img]/images/graemlins/diamond.gif[/img] 3 [img]/images/graemlins/club.gif[/img]
I bet, UTG folds, UTG+1 calls, Cutoff Fish raises, SB folds, I call, the UTG+1 calls.
Turn is K [img]/images/graemlins/club.gif[/img]
I check, UTG+1 checks, Fish bets, I raise, only Fish calls.
River is T [img]/images/graemlins/diamond.gif[/img]
I bet...
Comments on all postflop streets appreciated.
