slipping hands up or down?

[Andre]

Not always ,nothing in fighting is that set in stone:

When slipping towards their rear arm I agree fully; you either cover up from it smother it or pin it down with a glove.

If you slip your head to the outside of their leading arm then there is no threat to your head, so your inner arm may as well be ripping up their opening.

If your gloves are nailed to your temples then they are always higher than your shoulders...that limits your reply shots.
