I know there are probably previous posts on this but it is a two part question. So my wife and I do jiu jitsu at a karate dojo that has a jiu jitsu instructor come and teach a class. The dojo's association's annual karate tournament is coming up and they've added jiu jitsu this year since several of their schools have added it ( I actually started out at one of those other ones). We really only work standup in the month leading up to a tournament and I had one question for me and one for my wife. 1- For me, at my first school, I wrestled with some guys that were taller than me, but my main training partner now is built much more like a tree while the other guys were lankier. I have a few techniques that gave me reasonable success against them, but will they work well against someone not only significantly taller, but also heavier and stronger than me, or are there other techniques i should try? For the record my two best techniques were a really bad Harai Goshi type throw where I got myleg alongside them and them just kept spinning and hopping around until they fell, and/or frustrating them into pulling guard and just passing the guard as they fell. 2- For my wife, she is quite small and because there will probably be very few people in the women's comp (we only know of 3 for sure), she may face someone with both a height and weight advantage. On of the 3 we know is going is about 10 inches taller and weighs 10-15 lbs more. She can pull guard very well (better than me), but we want a few other weapons in her arsenal. I just wanted to see if there were any female grapplers or guys who teach a women's class out there that know a few specific takedowns that have a decent success rate for a smaller, lighter girl?
