AA hand: raise this river?

[surfdoc]

I am stuck in the middle of a 13K hand 200BB dowswing so maybe you guys can set me straight. I have been here before so it is nothing new. I think I am playing well for the most part but seem to be zigging when I should zag. Kinda a common feeling when you are running bad it seems like every decision seems wrong. This one okay?

Villian is 40/13/1.8 and seems pretty typical bad over 100 or so hands.
