Blocker in PLO
A hole card that reduces the combinations of strong hands your opponents can hold, most commonly used to justify bluffs.
What it means at the table
A blocker is a card in your hand that makes it less likely an opponent has a specific strong hand.
Why it matters
PLO bluffing relies heavily on blockers because opponents connect with boards too often for random bluffs to work.
Decision checkpoint
Ask this before money goes in
Table question
Does this card block the hand I am trying to represent, and does my line credibly tell that story?
Rule of thumb
A blocker helps most when it removes nut combos and matches a believable value line.
Table example
Holding the A♠ on a completed spade board blocks the nut flush and can make river pressure more credible.
Leak to avoid
Bluffing just because you have one blocker while ignoring opponent type, line, and whether your story represents value.
