10/20 party 6max -- AA on a dry board

[THATWACOKID]

the game is going playing pretty standard for 10/20.

big blind is schnie23 who from what i've seen so far is a solid laggy regular.

button is tightish, 20/10 preflop stats. and not very aggressive at all.

utg folds. i raise to 65 with AA. button calls. big blind calls.

flop: Q 8 6 rainbow

big blind checks, i bet 175 into a pot of 205. button calls. big blind raises to 725. now what?
