Ace-x is doing me wrong 3 handed recently

[HonchoOverload]

Hey guys, I'm having a problem with Ax recently.

Situation is usually that I have 11-13x the big blind, and I'm the button. Usually I have a comparable stack to second and first has twice as much. I pick up a hand in the A8-A2 range, and push with it, and whenever I'm called I'm up against an ace with a bigger kicker, a pair, or KQ-KT and I'm running a race I really don't want to run at that point.

Is it better to just push 3x the big blind with something like 11-13x the bb and a weak ace on the button 3-handed, or do I need to keep pushing all my chips to pick up those all important blinds?
