Doing a fuzzy guard after 66KK completely defends against all three options. With all three mixups recorded, play it back and block the 66KK. This is where you practice your timing for a fuzzy. If done right, you will duck the throw, but still be able to block the kick or punch. If any of those three options connect on you, it just means your timing is off. When done correctly, you WILL defend all three options.
