Quick Question

Blinds are 75/150, I have a +average stack with 2.6k, nowhere near the bubble. Comperable stack minraises my BB from the CO, and I look down at A6. No read, but this is low stakes, and I tend to expect this to be a standard raise for a player if I see it for the first time. I've been calling here 100% of the time, but crap myself every time an A flops. Should I play all hands here? If not, what should I play?

I'm leaning towards raising standard EP raising hands, calling with small pocket pairs and suited connectors, JTo, and folding all else, entirely to keep myself out of trouble. Dumb?
