With Lichess Opponent Form, users can access this information directly within their current Chrome tab, eliminating the need for time-consuming redirections. The extension presents a small popup window that displays the average performance of the opponent, as well as a list of their recent games. This list includes details such as the opponents' names and ratings, the colors of the pieces used, the game results, and the rating changes.
