What is the checkmate pattern for 1 king versus 1 king and 2 bishops? The more specific the things that you say you would change, the better. The code takes about 5 to 10 minutes to run, but it does reach and print an answer. I'm particularly interested in knowing if the nested loops in the main function here could be refactored into something cleaner looking as the breaks and the state mutations make it hard for me to extract good functions out of them. I'm more looking for advice about the Python side of things than Chess-specific things. The weak King always tries to move towards the middle of the board, while the stronger side tries to checkmate. ![]() The stronger side has a King and two Bishops, and the weaker side has just a King. I've written a Python program to find the fastest way to a checkmate from a starting position. ![]()
