Turn to the left in Tango

I love this step for it simplicity, how it feels and how practical it is.
At any time during the tango walk, the leader can step outside partner with his right foot and by having a firm connection on the follower's back, he can stop her back momentum and redirect it to the left.

The follower would step around the leader's right foot, take a step forward and then spiral by leaving her weight on her left foot.

From this half turn position, the leader can create a circular cadencia creating about 180 degree turn and coming back to the line of dance.

One of the things that I love about this step is how easy it is to execute in a crowded room and how easy it is to execute in close embrace. It also an easy step to pull out of your pocket in case of a need to do  a sudden change of direction or to kill some time while there is an opening on the dance floor.
