Lesson 9: Rotating over obstacles

You can skip over low obstacles with the J in two ways.

When entering with IRS, you can do this skip with the I.

For this you need to enter with a counter-clockwise IRS, then rotate again. Then you should DAS to the right and rotate a last time.

The same principle works in the other direction too. In this case with the J you need to be careful with the lock delay, since you have to go right one column before going left.
