Four Piece Combination Checkmate

The Bishop pair, a Rook, and a Knight were all involved in my checkmate of the Black King in this Fischer Random correspondence game recently concluded. As this was played under Fischer Random rules, the major pieces at the opening are positioned differently than in a standard game. This game’s opening board is displayed before the move record here, and the position of pieces at game’s end is shown after.
