Prompt Engineering Chess

Test your prompt engineering skills by writing prompts and battling them against each other! Your prompt template can access the board state, the move history, and a list of legal moves, and the game engine selects the first legal move in the string response from the LLM you query. My best prompt so far ignores the board state and the move history and just tries to play mates, make captures, and promote pawns. Can you do better?

    I created a daily challenge for Prompt Engineers to build the shortest prompt to break a system prompt. You are provided the system prompt and a forbidden method the LLM was told not to invoke. Your task is to trick the model into calling the function. Shortest successful attempts will show up in the leaderboard. Give it a shot! You never know what could break an LLM.
