F2L 36
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm

How to recognise it
Corner above the slot with white facing right; the edge is in the slot but flipped.
Its inverse is another case
Do the 36 algorithm backwards, R U' R' U F' U F U', and you are solving 31.
That's why CubeDojo never scrambles 36 that way: it builds a random state with the case fixed, so you practise 36 and not 31.
