How do YOU use the auto check, raise, check/fold, check/call buttons?

[KnickNut3]

I use autofold frequently PF and if I have a weak hand in the BB (or if I had a low pair didn't hit my set and there's already a bet and calls in a pot too small to draw to 2 outs).

Sometimes if I'm busy I'll raise auto PF. The -EV of the tell is worth it for the +EV of speed/tables, plus I will sometimes click raise very very quickly if I'm trying to steal blinds later so it looks like I have a good hand I would have raised with regardless.

I also use it as a bluff, e.g. if I tried to steal blinds and was called, as soon as it's checked to me I autobet so I represent a stronger hand.
