Resteal

Also known as: re-steal, restealing, 3-bet shove

Re-raising (usually all-in) over a late-position open with a short stack to exploit the opener's wide stealing range.

A resteal is a counter-attack: an opponent opens to steal the blinds from late position with a wide range, and you jam over the top to take it down via fold equity. It works best at 15-25bb, deep enough that your shove is a meaningful threat but shallow enough that the opener cannot profitably call wide.

The key inputs are the opener's steal frequency and fold-to-3-bet number. Against a player opening 45% of the button and folding to shoves 60%+, even hands with poor showdown value resteal profitably because fold equity carries the play. Blockers help — an ace or king in your hand reduces the opener's strong continuing combos.

Near the bubble, ICM cuts both ways: it widens your resteal threat against covered openers (they cannot call) but tightens it when you are the covered stack risking a bust.
