Hey!

I've just returned to Toribash after long break and I need some help.

I decided to play mostly in aikido, but I completely forgot how to do it. How to throw opponent to the ground? I try to lower myself (relax all, contr knee) while grabbing him, but I usually ended pushed to the ground...
How many openers should I know? I can do 1 opener with kick (it's possible to do it in both relax and hold stance) and I'm working with throwing opener, but it seems to be too few.
