Poker is a game of skill and strategy that requires players to make the best decisions possible based on the information available to them. One important concept in poker strategy is the idea of "blockers."
Blockers refer to the cards a player holds in their hand that make it less likely that their opponents have certain strong hands.
However, knowing what blockers are and when to use them is a completely different game, but luckily, the folks over at WPT Global have nicely outlined when you can and should use blockers when playing poker.
