F2L 29
The algorithm, how to recognise it and how to practise it without cheating.

How to recognise it
Corner in the slot with white facing you; the edge is at the front of the top layer, its front sticker matching the front centre.
Its inverse is another case
Do the 29 algorithm backwards, F' U F R U R' U2, and you are solving 30.
That's why CubeDojo never scrambles 29 that way: it builds a random state with the case fixed, so you practise 29 and not 30.
