Positions chess engines don't understand
When OpenAI trained their Dota model to beat people 1v1 mid SF, they had a contest at The International (the big yearly dota tournament, RIP) like &quot;can you beat OpenAI&#x27;s new bot?&quot; and had a big bucket of prizes for anyone that could.<p>By the end of the night, the bucket was empty. People learned to cheese the bot by running &quot;out of bounds&quot;, so to speak -- normally in a 1v1, you&#x27;re supposed to stay close to your opponent, since they&#x27;ll be getting stronger if you leave. But the bot didn&#x27;t know how to deal with it when you snuck behind it (normally an insane maneuver, almost guaranteed to cost you the game in normal play) and prevented his army (called &quot;creeps&quot;) from running to the middle lane. (All you have to do is go wave your hand at them, and they mindlessly chase you.)<p>People did that over and over, and your own army would eventually overwhelm the bot and win. :)
