Quite-checkmate

I used one minute for five checkmates today. It was a warm-up for my tourney game which will start in 1 hour.  I postponed rounds 1 and 2 because I was travelling in the weekend. Today I will play a talented junior from Vietnam. I got up at 5:30 and worked between 7am-1:00pm in the book warehouse. I ate around 10 bananas for lunch. I'll have 20 minutes rest and then go to play. I will report  the result when I arrive home and post the game tomorrow. Until that I show the checkmate I liked most today. It had a solid move which created a winning threat. Can you find it?

Have a great day!
