Sir, You are kind to let me and others
have a go at this. Checkmating the
knight is easier than you think if
you can get bishops or the queen
to place pressure on the knight

My Proposal is Knightmate Chess:

It is the same as standard chess but the knights and kings swap places, meaning you start with two kings where the knights are and one knight where the king is. Castling is permitted with the knight and en passant is still available. A pawn can promote to a king but not a knight. Just like the king, a knight cannot move into check, and it must move out of check on the very next move. All other rules are the same as standard chess.
An intriguing game full of suprise moves!
