I recall reading somewhere in the last few days how a tournament move is determined by +cEV which is to say how well is it expected to add to your chip stack. (c=chips)
Before you get too short-stacked and lose all fold equity in a tourney, you might face situations where you need to play more aggressively, so shoving with a made hand or a strong hand like the ranges you specified works really well in certain spots.
If you know that you will be facing elimination or become crippled in the tourney if you don't make some moves, ask yourself: "If I shoved here with this same hand twenty times in a row and got called, would I be likely to have more or less chips in the end?" I think that is positive chip expected value
, combined with ICM this becomes a serious edge in your tournament strategy.
Hopefully others will agree as well.
