Black makes the move then checkmate!

After losing 4 games in a row I start to regroup myself. I tell myself don’t think about victory anymore but instead concentrate on the chess board. My opponent who has higher ranking than I am starts the game with a left pawn opening, I told myself if I want to end my losses then I better stay cool and play my usual game. I was pressured by him during the first half of the game but later on he makes a mistake which allows me to come back and win that game!

If you want to win then you need to forget about the previous losses and concentrate on the game!
