I disagree, a pre-flop push to me is nearly always AK or a pocket pair early in an MTT. The guy either could be solid and have AA and assume this early in an MTT some idiot is going to call him (I've made this play with decent results), or is a poor player himself with a pocket pair and you can likely pick up his chips in a better situation than a coinflip later. You should not be calling off over 30xBBs with AK unless you have a very specific read that the pusher is a maniac.
