mate by KNIGHTS ONLY TEAM
Tournament points: 18,876
Team leader: game_spectator
1. You had only knights (your king is permitted too, if it is impossible to get position without king; note, that in horde games white do not have a king at all)
2. You made a mate to your opponent
3. Your opponent did not have pawns or pieces that prevented his king to move and so help you to mate him.
An example of such a mate: lichess.org/TpCA8ZU6#259
To join the group make a join request and include a link to your game in the request. Then I shall look at your game and confirm your request. (Alternatively, you may make personal message to me with link to your game.)
If you still not made a mate by knights only, but want to make such a mate, then play with low level Stockfish AI on lichess and mate it with knights only. If your opponent does not cooperate with you, then 2 knights is not enough to made a mate by knights only. So, generally, you should promote one or more pawn(s) into knights.

It is possible to mate by knights only in crazyhouse (but I have no such a mate against a real person, only against Stockfish): https://lichess.org/z12QCDzx#299 See also https://lichess.org/foru
