After watching Frotch vs Groves 2, it kinda reminded me of how effective that lead hook + cross combo is. The lead hook comes from the side and the cross right down the middle which is why it is so effective against the 'hands up' defense. I seem to get caught by this punch a lot and it also is very effective for me too when I use it. edit: Ill also add that I'm struggling with defending the cross after blocking the hook because it spreads my arms out wide and leave a huge hole right down the middle. How do we deal with this combo in a Muay Thai context where the hands up defence is used more commonly?
