In the Four Knights Defense, it is well known that White should not immediately play Nc3 because it allows the center fork trick, as shown in the image below.
No matter how White decides to handle the trick, Black is at least equal or better. In the current blitz game, White tries a common variation with Bxf7+ first, but this line isn’t very good for White because Black usually gets a nice attack. Although White didn’t play the most aggressive continuation in the game, the position was quite sharp and interesting. Hope you enjoy it and learn as much as I did from the analysis!
