go for broke

Example: “Down by twenty points, the team decided to go for broke.”

Origin: Grew out of Hawaiian Pidgin craps slang in the early 1900s, where wagering literally everything on a single roll of the dice meant risking total bankruptcy — you'd "go for broke" and either win big or end up with nothing at all. The earliest documented use is the title of a 1935 Honolulu song, "Let's Go for Broke," copyrighted by Harry Owens. The phrase reached its widest fame during the Second World War as the official motto of the 442nd Infantry Regiment, a US Army unit composed largely of Japanese-American soldiers, whose battlefield reputation for total, unhesitating commitment gave the old gambling phrase a far more serious meaning than a dice table ever could.
