I agree it is more easy to win the game after 16...Kb6 but it does not mean that 3...Bc1 does the game longer because even if the game after 3...Bc1 is 20 plies longer it means that 16...Kb6 makes the full game longer. From practical point of view f5 seems to be the best chance and not Bc1 because white may miss the right moves before 16...Kb6 Uri
