The engine’s best move here is exf5, and that is the move to understand first. The idea is simple: meet the advance directly, then follow up with Qf6 Qh5+ g6 as given by the engine line. That tells you this opening is not about passive defence. You are expected to stay concrete, respond to checks calmly, and keep the king safe while your pieces catch up. If you hesitate, White’s lead in comfort can last for a long time.
