What is Blocker in poker?

A blocker is a card you hold that prevents your opponent from having certain strong combinations of hands, thereby impacting their overall range. For instance, if you hold the A♠ on a board with three spades, you are blocking your opponent from having the nut flush. This dramatically increases the profitability of bluffing, as you remove crucial calling hands from their potential holdings. Recognizing and utilizing blockers is a sophisticated aspect of high-level poker strategy, allowing for more precise bluffing and value betting.
