The phrase "went for broke" typically means taking a great risk or putting forth maximum effort to accomplish a goal. Its antonyms would be more cautious and conservative approaches, such as playing it safe, taking it easy, or being moderate. Other antonyms might include holding back, retreating, or giving up altogether. These opposite actions demonstrate a preference for caution over boldness or a willingness to sacrifice potential success in order to avoid potential failure. Ultimately, the choice between going for broke or taking a more conservative approach depends on the individual's priorities and their willingness to take risks.
