How to recognise it
Only the centre is yellow on top, and the left and right sides each show a full yellow bar. Hold the bars left and right.
Its inverse is another case
Do the 1 algorithm backwards, F R' F' R U2 F R' F' R2 U2 R', and you are solving 2.
That's why CubeDojo never scrambles 1 that way: it builds a random state with the case fixed, so you practise 1 and not 2.
