Blockers In Poker

Learn what blockers are and why ace blockers can make tournament shoves and bluffs more attractive.

Definition

Blockers are cards in your hand that reduce the number of strong hands your opponents can have.

A hand with an ace blocks some ace-high calling hands and premium combinations, which can improve shove and bluff candidates.

A5s can be a useful short-stack shove because the ace blocks hands like AA and AK while the suited wheel card adds equity.

Overvaluing blockers without considering stack depth, position, and how often opponents actually fold.

Related terms

Fold equity is the value you gain when opponents fold and you win the pot without needing to show down the best hand.

An open shove is moving all-in as the first voluntary action before the flop.

Push/fold strategy means deciding mainly between moving all-in or folding, usually at shallow stack depths.

FAQ

Do blockers guarantee opponents will fold?

No. Blockers only reduce combinations. They do not remove all strong hands from opponents' ranges.

Are ace blockers useful in tournaments?

Yes, especially in shove and re-shove spots where reducing premium calling combinations matters.
