kihon kumite yonhonme (the pictures can be clicked on to enlarge)
Find the right distance.
Ukemi: left suriashi, attack with tobikomizuki jodan. Think of the right hikite (withdrawing the hand against your chest), it will direct your concentration towards seikatanden which will enable you to re-attack immediately. Do not only use the upper body, but use power in your knees. It feels as a 'jumping' punch.
Torimi: Twist the hips to the right and perform taisabaki. The right arm parries the attack. It isn't necessary to use much force, simply re-direct the attack towards your rear. Keep your left arm in front of your chest.
Ukemi: Attack once more with a right gyakuzuki no tsukomi. Take care to put some 'weight' in the fist.
Torimi: perform another taisabaki with the whole body, using your left foot as a support. Parry the attack with a shuto nagashi uke in nekoashi dashi.
Torimi: suriashi forward, as if jumping towards ukemi's chest; your left shuto presses against the right upper arm and using a right nakadachi ipponken you attack suigetsu. Remain in nekoashi dachi to be able to move immediately. Kiai.
