Ippon-seoi-nage into Uchi-makikomi.

Combination (Renraku-waza).

Techniques
----------
1. Ippon-seoi-nage (一本背負投), the one-armed shoulder throw.
2. Uchi-makikomi (内巻込), the inner wraparound.

About
-----
When the shoulder throw stalls with their arm still trapped high, winding inwards turns the stall into the throw: you keep the arm, add your body weight and roll through instead of lifting.

Step by step (standard right-handed form)
-----------------------------------------
1. Turn in for Ippon-seoi-nage, your right arm under their right arm and their sleeve in your left hand.
2. Feel the lift fail because their hips are low and their weight is behind you.
3. Clamp their right arm tightly against your right shoulder and chest so it cannot be pulled free.
4. Keep turning to your left and drop your hips lower than theirs, winding your body inside their arm.
5. Commit your weight forward and roll over your right shoulder line, taking them with you.
6. You both land on the mat; land on your own side, keep their arm supported and do not drop your weight onto their shoulder. Build up gradually.

Receiving it
------------
The throw stalls but your arm does not come free, and that is the danger: they clamp it, wind inside it and roll, and you go with them whether you have chosen to or not. Do not fight to keep your feet once the arm is trapped. Turn with the roll, keep your chin tucked, and slap with your free left arm as your side lands. Their weight must not arrive on your trapped shoulder, so build this one up gradually and only with a partner who knows it is coming.

VI judo notes
-------------
The stall is felt as your own hips being too high and their weight sitting behind you, and the answer is to lower and wind rather than to lift. Their arm against your shoulder is your one reference all the way to the mat: clamp it, keep it and land on your own side. Because the finish is a committed roll, agree the working direction beforehand and check the space around you.
