The Deadly Sacrifice On G7 - An Original Chess Puzzle By cjxchess16

Hello all viewers! This is the first puzzle I am posting that I have not created myself! A few weeks ago, I made a forum thread asking if anyone wanted to make a chess puzzle with me, and a Chess.com user called cjxchess16 created a very nice chess puzzle alone. It was then shared with me in the forums, and I decided to post it here, since it was very well done. Viewers please comment below if you like it!
