OLL 43
The algorithm, how to recognise it and how to practise it without cheating.
Recommended algorithm
F' U' L' U L F6 moves · with the left hand
Alternatives
(U') R' U' F' U F R6 moves
How to recognise it
A P shape: the right column and the back edge, with a full yellow bar on the left side.
Its inverse is another case
Do the 43 algorithm backwards, F' L' U' L U F, and you are solving 45.
That's why CubeDojo never scrambles 43 that way: it builds a random state with the case fixed, so you practise 43 and not 45.
