AA facing big raise live

[SSky06]

1/2 Turningstone Casino. 8 Handed

Hero has 175. Viewed as TAGish. I've been at the table for about 2 hours and have barely played any hands due to the fact that I get K4 every hand. I've showed down one hand which was a set.

Villian has 200ish. Solid player who came over from 1/2, 400 max, to play at our table with his two sons (who are CO and button respectively). He's done nothing out of line and has been playing pretty well. The one hand we've been hooked up in so far he told me the truth about what he had when I was quizing him about his raise.

SB has 400ish. Loose/Weak donk. Been playing for about an hour and it's pretty clear he doesn't know what he's doing at all. Calling big raises with K6os, calling preflop shoves with garbage. He's not drunk, he just is sitting there quietly playing really bad (and coincidentally, he's winning).

Hero dealt A [img]/images/graemlins/club.gif[/img], A [img]/images/graemlins/heart.gif[/img] in MP1

UTG folds, UTG+1 folds, Hero makes it $12 to go, MP2 folds, CO folds, Button folds, SB calls, BB/Villian calls.

Pot: $36
Flop: K [img]/images/graemlins/heart.gif[/img], 9 [img]/images/graemlins/spade.gif[/img], 6 [img]/images/graemlins/club.gif[/img]

SB checks, BB checks, Hero fires $25, SB folds, BB almost instantly says "let's make it $100." Hero?
