bottom set on monotone flop in 6-way pot, villian giving massive tells

[elliot]

normally i wouldn't think this hand is all that interesting, except the psychological aspect of it...given the obvious tells i am absolutely sure that villain thinks he has the best hand, the problem is that his hand range includes hands that i have beat

$100 buyin b&m tournament

Blinds: 100/200

Hero: 11k
villain: 12k

villain limps in MP, two more limpers and i call on the button with 6 [img]/images/graemlins/spade.gif[/img] 6 [img]/images/graemlins/heart.gif[/img], SB completes and BB checks.

flop (6 players): $1200 in pot

6 [img]/images/graemlins/diamond.gif[/img] 7 [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/diamond.gif[/img]

SB checks, BB checks, villain bets 1k, folded to me, I call, blinds both fold.

Turn (Heads-up): $3200 in pot

villain takes his time stacking chips, sighs, then bets $2100. my immediate reaction is that he is pulling a weak=strong, but still am not really sure where i am at, especially since we saw the flop 6-ways, so i call.

(weak-tight thinking, but his turn bet allowed me to get away from the hand on the river if a diamond falls and he shoves in case he has a hand like A [img]/images/graemlins/diamond.gif[/img] Q [img]/images/graemlins/spade.gif[/img] that would almost always call a shove both here and possibly on the river even if he doesn't make his flush)

River (Heads up): $7400 in pot

villain sighs, says "alright, time for you to send me home kid, I'm all in" and haphazardly just kinds of spills his chips everywhere, ($8,000) and gets up from his seat.

this is a massive tell, and it is just screaming that he knows he has me beat, although since i have shown zero strength the entire hand i might as well have a busted flush draw that cannot call any bet.

i genuinely feel it is possible that he has a hand as weak as AQ given the action without the tell, but with this tell i feel that he can certainly beat aces here.

i go into the tank, and say that I can beat 67, and he tells me that i should definitely call.

Call or fold the river?

Would you play the flop/turn differently?

am i an idiot thats over analyzing the play of an obviously weak player?

any insight whatsoever from players that are better than me, is greatly appreciated.

results to follow.
