Yes, it does happen in real life. I normally play the Petroff in response to 1.e4 and then launch into the Stafford Gambit, which also has the opportunity for the Legal’s Mate. White chose an unorthodox line that lead to a position similar to the Four Knight’s Defense.
This short game if from an online, turn-based game. It is really self-explanatory, but thought my readers might enjoy it.
