WORD ORIGIN

Go for broke is originally a gambling expression and refers back to the word "broke", meaning to have no money.

If a poker player throws all of his money into the pot (the pile of money or poker chips to be wagered that sits in the middle of the table) and risks it all on one bet, then he is said to "go for broke".

Meanwhile, the phrase is liberally used in sports, business or any kind of personal endeavour. In the last minutes of a football game for instance, a losing side might send its goalkeeper down the field to help his team score a goal, thus leaving its own goal unattended – a good example of going for broke.
