Frank Marshall's "Gold Coin" Move astounds me!

Reading a recent blog/article of a GM Serper on chess.com I was overwhelmed by an amazing move Frank Marshall made.  Unfortunately the article didn't share why it was so amazing.  As I analyzed it further the depth of the variations that all led to Frank winning was incredible.  Here is the move and the many variations that could follow that all lead to him winning.  Such brilliance!

I hope you enjoyed seeing all the variations that I could find that erupt from this astounding move.
