Chip spewing with aces?

[coinflip]

Just recently sat down at table, so no good reads. What's my action when I get raised on the turn? Call it down? Raise? Fold? This seems to be such an obvious place to bluff a scare card ...

calls down. it's heads up right?

Against a total unknown &amp; on this board, I'd call down. I think that much more often than not you're going to see an unimproved pocket pair that's figured you for whiffed overcards, but if you 3-bet there's a fair chance he lays down on the turn. But you're also going to see the odd 7 hand or even a 56s, and there's the chance that he slowplayed 88 or 44.

No matter what happens, this one probably produces a note on MP2.
