In this position, f5 was played. The reasoning is that Black's king is still in the center, so if White decides to start a kingside attack the king can just to run to safety. But this doesn't make any sense! Black could just castle after the move. Am I missing something?

user18809: Black could castle, but that doesn't make the king any safer! White could follow with f5 0-0 Qd2, threatening both f6 and Bh6.
Anyway even if Black could castle that doesn't make f5 a bad move (the only downside being the e5 square becoming a bit weak)
