F2L 13
The algorithm, how to recognise it and how to practise it without cheating.

How to recognise it
Corner above the slot with white facing you; the edge is beside it in front, its top colour matching the corner's right sticker.
Its inverse is another case
Do the 13 algorithm backwards, F' U F2 R' F' R2 U' R', and you are solving 2.
That's why CubeDojo never scrambles 13 that way: it builds a random state with the case fixed, so you practise 13 and not 2.
