Search for the right distance.
ukemi: Search for a moment when the concentration of the performer slackens and attack with a tobikomuzuki jodan on full speed and strength. Use the whole body for the atttack and try to find strength in seikatanden and the legs. This attack is often weakly performed, because only with the strength of the upper body and arm.
The attack is aimed at the chin. But if you don't move your body forward, it might happen that the chin is hardly touched. Therefor aim at a spot that lies a few centimeters within the chin.
torimi: Move diagonally left in taisabaki, at the moment of attack. The movement is driven from the hips and the body should move as one. That means that the feet should also move a bit (suriashi). If the feet stay put and only the upper body moves to the left, you'll be off-balance and you won't be able to perform the next action properly. While the movement is evasive, to become taisabaki it should be performed with the feel of an attack. The movement performed is jodan harai uke ending with the right fist pointing upwards from the elbow en re-directs the fist ukemi past the head (nagashi uke)
ukemi: Attack with a left gyakuzuki no tsukomi chudan. Make good use of your bodyweight.
torimi: Move slightly to the left in taisabaki. Beware not to move backwards. The left foot moves forward while the right foot goes backwards in one fluent movement that is driven from seikatanden. Re-direct the attacking arm backwards and attack at the same time with agezuki chudan (fist turned upside down)
