Context Mate-in-one dataset was designed to teach a neural network that can find these one move mates. All these position are a result of random matches between two monkeys (doing random moves). Care has been taken to ensure that there is only one solution to each Position. Content The file just has the FEN text and the best move (mate move). Acknowledgements The sole credit of this dataset goes to **np.random.choice()**. Inspiration Inspired by AlphaZero ... I will beat you one day (or not)!
