How it works
To start a new match, open the board screen and press the crop button — then keep the board visible and unchanged throughout the match.
Press the crop button once at the start of each match. darkSide auto-detects the board boundaries and saves the region.
Press the camera button at any point during the game. AI reads the position in under 3 seconds.
GNUbg equity engine calculates the optimal play. Autoplay mode executes it automatically.
