Counterfeit
When a board card duplicates part of your hand and destroys its relative value.
In depth
A counterfeit occurs when a community card duplicates a rank in your hand, reducing its relative strength. For example, holding two pair may become weaker if the board pairs one of your cards, as the duplicated rank diminishes your hand’s value compared to possible stronger holdings. This concept highlights how board dynamics can erode made hands without outright breaking them.
