Favourite Checkmate of Mine
Until this game proceeded to the 14 moves, the black didn't develop any pieces except one black knight.
I think it is the reason why the black lost this game.
Instead of the black move 13...a5, the black queen had to move to Qa5 and empty the d8 square so that the black king can avoid checkmate.
Just finished this game, very proud of myself! Good game marshallmassena!
