Re: Aikido against very high kicking (like in tae kwon do)
Watch the distance.
Get off the line. Slip the kick. Irimi or Sayu-undo.
Get off the line. Irimi tenkan behind. Pull down on shoulders.
Drop and roll into supporting leg.
Drop, grab the heel of supporting leg and apply sideway pressure to knee, sorta like Ikkyo to the leg.
Sample principles apply. Easier to take balance because only supported by one leg.
Train again kicks to get used to seeing the angle and it become pretty easy.
