We can bet 5k so as to...
Fold when he jams.
We will burn our equity (33%-48%) and sometimes (however rarely) fold a dominating hand.
We are gonna have the right price to call so folding is a mistake.
Induce and never ever fold.
It's debateable whether or not this encourages villain to get it in with many more hands than he would call our jam with. Lets assume he calls the jam with..
QQ+,AKs,AKo versus this calling range...
Villain folds 78% when we 3b.
We have 36% equity when called.
Our EV is +3820 chips.
We exit the tourney 14%
So we induce him to get it in with a wider range..
TT+,88-66,AJs+,AJo+ versus this calling range...
Villain folds 37% when we 3b.
We have 48% equity when called.
Our EV is +5850 chips.
We exit the tourney 33%
If you consider that you have an edge over the field, which is hard to gauge and usually overstated, then you probably should take the lower variance option since your tourney life and stack equity have more value.
