Queen-Bishop Combination Checkmate

I won this correspondence chess game recently when I checkmated the Black King with a Queen-Bishop combination checkmate. As this was a “480-chess” game, my opponent and I began play with the major pieces set differently than in a “standard” game. To help you follow the moves, I’m posting that opening position, followed by our full move record, and the board at game’s end.
