Gameplay

You are playing for white against a bot.
Select a piece and choose one of valid moves (they will be highlighted with green circles)

How bot works

This project is a chess game against a bot written using the mini-max algorithm and alpha-beta puring optimization.
The bot evaluates positions in which knights and pawns are in the center of the board higher, which allows him to play relatively well in the opening

Here are tables of the values of different pieces depending on their position on the board:

knight_value = [[2.5, 2.7, 2.8, 2.8, 2.8, 2.8, 2.7, 2.5],
                [2.7, 2.8, 2.9, 2.9, 2.9, 2.9, 2.8, 2.7],
                [2.8, 2.9, 3.0, 3.0, 3.0, 3.0, 2.9, 2.8],
                [2.8, 2.9, 3.0, 3.0, 3.0, 3.0, 2.9, 2.8],
                [2.8, 2.9, 3.0, 3.0, 3.0, 3.0, 2.9, 2.8],
                [2.8, 2.9, 3.0, 3.0, 3.0, 3.0, 2.9, 2.8],
                [2.7, 2.8, 2.9, 2.9, 2.9, 2.9, 2.8, 2.7],
                [2.5, 2.7, 2.8, 2.8, 2.8, 2.8, 2.7, 2.5]]

bishop_value = [[2.7, 2.85, 2.85, 2.85, 2.85, 2.85, 2.85, 2.7],
                [2.85, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0, 2.85],
                [2.85, 3.0, 3.05, 3.05, 3.05, 3.05, 3.0, 2.85],
                [2.85, 3.0, 3.05, 3.1, 3.1, 3.05, 3.0, 2.85],
                [2.85, 3.0, 3.05, 3.1, 3.1, 3.05, 3.0, 2.85],
                [2.85, 3.0, 3.05, 3.05, 3.05, 3.05, 3.0, 2.85],
                [2.85, 3.0, 3.0, 3.0, 3.0, 3.0, 3.0, 2.85],
                [2.7, 2.85, 2.85, 2.85, 2.85, 2.85, 2.85, 2.7]]

pawn_value = [[1, 1, 1, 1, 1, 1, 1, 1],
              [1, 1, 1, 1, 1, 1, 1, 1],
              [1, 1, 1, 1.05, 1.05, 1, 1, 1],
              [1, 1, 1, 1.35, 1.35, 1, 1, 1],
              [1, 1, 1, 1.35, 1.35, 1, 1, 1],
              [1, 1, 1, 1.05, 1.05, 1, 1, 1],
              [1, 1, 1, 1, 1, 1, 1, 1],
              [1, 1, 1, 1, 1, 1, 1, 1]]
