Checkmate at bedtime

• We had dinner guests who stayed until 9:15pm
• Began playing chess at about 9:35 ... just before my 10pm bedtime
• Nice win ... 
• I did fail to protect my White King as well as I like but ...
• My offense was punishing:
• Note the Knight protecting the Pawn
• The White Pawn protecting the Knight
• The Rook protecting two Pawns
• Black ahead by two Pawns ... but 
• I just plain beat Black down!
