A basic chess engine coded in python, with a GUI that enables you to use more advanced chess engines as bots. It was a personal project made during high school (the code quality is... bad).
Krevetka (or Креветка) means "shrimp".
The bot captures a screenshot and searches each individual pixel for colors belonging to the chessboard. It then determines the chessboard's location on the screen, ensuring its complete visibility, and begins playing.
Currently, the bot is compatible with the following websites (only tested under WINDOWS):
- lichess
- chess.com
- chessfriends
- chess24
The minimax algorithm explores every possible position up to a predetermined depth. It executes a recursive function which evaluates each position and determines the optimal move. Krevetka uses this algorithm with a maximum depth of three. Instead of a recursive function, I implemented it using "for" loops, as these tend to be quicker in Python.
