Thanks very much for this...so, N/S/E/W, based on which way tori is facing when she initiates her attack? I will give that a try and see if I can make it work.
I think you have the idea.First you have got to start together at a fixed point ie a directional position which you can relate to.A good idea is to determine North /South /East /West ie the direction of ukes ukemi. Do this map ref.from your point of view as Tori.So you would face due North/Uke faces .SouthSelect Migi Gyaku Hamni katatedori..Then proceed from that point.The first three are easy peasy , no. 4. is the awkward one.luck.Cheers, Joe.
