AA facing shortstack all-in with one player behind

[Bodhidharma]

I bet the turn to $7. To me checking on the turn multi way on a relatively dry board is weak.

If you're going to go for a check raise with AA its better to do it HU if you're pretty sure villain will be with a better hand, but since CO is all in you will have a side pot vs. BB which increases your chances of winning that pot and I think you're ahead enough here to make that play.
