Have you ever played a chess game with a "ringed piece"? In these games, "a ring or band is placed around a particular piece, and the player giving odds must checkmate with that piece" (Source: Wikipedia).
The following game depicts Max Lange playing with his queen's knight as a ringed piece. It is interesting to see how both players attempt to deal with this unusual handicap. A Muzio Gambit soon leads to a dazzling series of sacrifices from Lange. Although the game is not played perfectly, it is still quite fun to watch, and the final mate, nearly a pure one, is very pretty.
