Oh, I see. Nope, you're right. Start at step one! I was a bit ahead of myself.

My primary instructor was more than difficult for anyone to take down. Wrestler, judoka,etc....He was/is exceptional in many areas though as a 4th degree black belt.

However, I was exceptionally easy to take down even after years of Goju training UNTIL I learned to defend the takedown (sprawl) and also learned groundfighting from those that knew it.
I like to think I'm getting much better at groundfighting. I even teach several ground techniques in my class.

Single and double leg
Sprawl
Armbar
Americana or keylock
RNC
Knee bar
Ankle lock
etc..

Coaching someone over the internet doesn't sound like a good idea, but it's great for discussion. I'd say total I have about 3 months of jiujitsu training and only one month of it is consistent practice and training.

I'm glad I tried the mixed martial arts thing. I enjoy my karate training more than the the muay thai, and I prefer the dojo experience from the gym experience with a cage, but now, I know that I can keep up with mixed martial artists with my karate training and I met a lot of good people. Plus, they send me notices on their events and it's better watching fights when you know the person fighting.

I'm going to try sitting in seiza and just stalling next time. It sounds like a good idea. Especially since so far I was the one on the offense and he just breaks my offense down like it's nothing. It's rather annoying because up till now, I was able to win sparring against other by just applying pressure until they got tired and I won.

Welcome to BJJ! Against people where you are at more or less at the same technical level, factors like athleticism, strength, size and aggression are usually what seperates people in a fight. Roger Gracie is probably the best grappler in the world today. He's beaten pretty much every top BJJ practioner in the world. He is great technically, but what helps get him to the top of the pile is that at 6'4" and 210 lbs he is usually a lot bigger than his opponents.

You have to, as the Chinese say, "eat bitter" when you start off training. You have to accept that no matter what you want to do in BJJ, you're going to spend the first 6 months or so getting tapped out. What you've got to focus on is defense initially: staying out of dangerous positions, escaping attacks, getting in to strong positions. That, IMO, will serve you best long term.
