This puzzle if from a recent game I played. I really enjoyed the final moves in this game and finding the game winning move. See if you can find it.

I liked it because, at first, I was ready to just snatch that lowly rook off the table and prepare to follow the fleeing black king to the left side of the board, but then I saw how I could mate by sac'ing my queen. It wasn't a hard discovery, but just made me feel nice to pick up on something to end the game quicker.
