F2L 11
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm
U' R U2 R' U F' U' F8 moves
Alternatives
F U2 F2 U' F2 U' F'7 moves
How to recognise it
Corner above the slot with white facing you; the edge is beside it on the right but not paired: its top colour is that of the corner's right sticker.
Its inverse is another case
Do the 11 algorithm backwards, F' U F U' R U2 R' U, and you are solving 1.
That's why CubeDojo never scrambles 11 that way: it builds a random state with the case fixed, so you practise 11 and not 1.
