Strategy
Blockers in poker
Cards in your hand that reduce the number of strong hands your opponent can hold.
Every card you hold is a card nobody else can have, which quietly reshapes your opponent's range.
Holding the ace of spades removes every combination containing it. If the board shows three spades, you hold the only card that makes the nut flush, so your opponent cannot have it, no matter how they play.
Blockers are counted in combos. Against an opponent who would only continue with aces or kings, twelve combos in total, holding one ace and one king cuts that to six.
The effect is real but small. It breaks close decisions; it does not turn a fold into a call on its own.
