AJs preflop. cap or call?

[JimmyV]

Capping increases variance with no likely benefit, and yes, of course, you may be dominated. Don't do it unless you really have specific reads that give you an idea about the way you're going to make a move for the pot later if the board is a certain way.

Fundamentally I think capping is foolish in this scenario unless you've really thought your reasons through.
