In poker, “Broadway” is a slang term used to refer to the highest straight possible on the board. It is also known as a “royal straight” or “ace-high straight,” and consists of the cards A-K-Q-J-10, all of the same suit. For example, if the board shows A-K-Q-J-9, any player holding a 10 in their hand would have a Broadway straight. The term “Broadway” comes from the famous street in New York City, which is often associated with glitz and glamour.
