BB is a fairly tight-aggressive (15/8.5/2) over about 100 hands, I suspected that he does adjust his raising standards based on position, and that he has just had a bad run of cards.

I dont see much you can do here... possibly take a shot on the turn? Betting the river is useless obviously.
Sometimes Ill go to war here and c/r flop and lead turn to boot out the better ace, but seeing as he is content to check down his AK, either take a shot on the turn or have "nh" ready to go in the chat box
