Lichess has great variants to play. If you haven't tried crazyhorse or multi-player version bughouse, highly recommend it. In crazyhorse you can put captured enemy anywhere on the board as your own piece. Likewise in bughouse, you play with a partner (where you are opposite colors) against another team. You each play your own game against the opponent but each opponent piece you capture you can give to your partner to place on their board and vice versa. First person to win the game wins for their team. It requires good communication and a different strategies than traditional chess as you need to account for two games and the flow of pieces on both boards.
