Your turn
Sign in to play against your Doppelganger
Your Doppelganger AI starts by using Stockfish for its moves. As you play more games, it learns your personal playing style and begins mimicking your moves!
When the Doppelganger reaches a position it hasn't seen before, it falls back to Stockfish. It also recognizes transpositions, so it may jump between your learned moves and Stockfish throughout the game.
Fast-track your Doppelganger's training by importing your past games.
One-Time Only: You can only do this once! Games will populate your database but will not affect your Elo rating.
