This chrome extension will help you analyze your chess.com games on lichess. Just click the icon in your extension bar when you're on a chess.com game and a new lichess tab will open with your game. How It Works: - User clicks the extension icon when on a page like `chess.com/game/live/*` - The extension gets the pgn from chess.com share option. - The extension creates a new tab with url `lichess.org/paste` and imports your game. - The extension will automatically turn on local analysis and flip the board if you were black.
