Thanks for your answers.
I totally agree to deadzone and the premium hand. However in the situation I decided just to raise 3bb to avoid being all in before the flop just in case the flop showed multiple overcards. The button called. Flop saw Q64 no suits. I went all in quickly for 3/4 of the pot, button called with AK. Maybe I should have waited a bit before going all in, as it might have been perceived as "stealing".
The button called my all in to see an Ace on the turn. (That's painful).
What would you have done?
Cheers
