Osu!
I guess I am not in a perfect position to give advice, as I had my first tournament fight yesterday and lost it ^^ but i'd say, try to stay focused, get up, no matter how often you fall and try to counter as many attacks, as you can!
I didn't think it is so hard, when you are on the mat. But when I stood there, I saw my opponent aiming a mae-geri at my chest, and even though I knew how to dodge/block, my feet and hands wouldn't move. I think he hit me about 10 times mae geri and I didn't block a single one, because, I was some kind of afraid to put my hands down and open up for a jodan kick. And I tried to dodge, but my feet simply wouldn't move... However, I learned many things from that fight and I hope I can use it next time *g*
I'm really looking forward to seeing the video of the fight, some friends made. Maybe that's good advice too... try to get videos from your fights, and look at your mistakes. I guess that also helps alot
Osu!
