Final answer:
To become a chess or checkers champion, one must use heuristics - general problem-solving frameworks or mental shortcuts.
Step-by-step explanation:
To become a chess or checkers champion, one must use heuristics. Heuristics are general problem-solving frameworks or mental shortcuts that are used to solve complex problems. Unlike algorithms, heuristics do not provide specific step-by-step instructions but rather offer a flexible approach to finding solutions. Chess champions, like players in any game, rely on heuristics to make decisions and strategically navigate the game.
