    ChatGPT Chess Lesson in Messi Instagram Ad Features Incorrect Board Setup

    Report first recorded Oct 23, 06:56

    In an Instagram ad featuring Lionel Messi, ChatGPT taught a chess opening called “GOAT Horns” but on a board where the king and queen for each side were swapped. This error allowed the suggested opening (1.e4 a6 2.d4 c6) to force a checkmate in four moves from the flawed setup, though it would not result in a forced mate on a correct board. The post garnered approximately 1.9 million likes and 19,600 comments in about a day.
