party $109 AA decision

[chio]

party 40k gtd, $109 buyin
about ~400 left out of 800

i have ~11k, villian in this hand covers (avg stack ~5k)

i've been playing tight, villian is a loose player who's hitting a lot of cards and has built a big stack. he limps in a lot and i saw him call a flop and turn bet with Qd7d on KcTc9c board

anyway, here's the hand, call or fold the river? and would you play any other street differently?
