Jeez! - if I allowed myself to feel demoralized every time I got my a** kicked in sparring I'd never ever continue with the sport but I've been sparring better fighters than myself for several years now.

I have never ever met anyone who didn't get their a** kicked a lot when they began and even the best fighters I know (and really admire, respect want to be etc etc) all have off days occasionally.

The up side of this humbling sport is you can enjoy the little victories more. When I spar I might not be 'beating' my opponent but if i manage to block something I usually struggle with or land something I couldn't get i smile about it for at least a week!

Chances are since it's only your fourth sparring session they may have felt you did OK in the first three sessions and decided to up it a little.

My thoughts on the right hook would be that if he's able to hit you with it he is getting in very, very close to you. Maybe work on your distancing and movement to keep him away more. Don't get caught on the ropes.

It's hard to comment on the guard without seeing how you hold it and mine is not perfect so I will leave that question for someone else.

If you like what you are doing don't feel demoralized by this one experience - it happens to absolutely everyone especially when your coach feels like you are ready for a new challenge - which is a compliment really!
