This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL09 is one of the 'Knight Move' cases with a diagonal 2×2 block and additional stickers forming a staircase.
Recognition：
A 2×2 block sits diagonally, with two more yellows forming a slanted staircase.
Memory Hint：
Think of the shape as 'diagonal block + steps'; this makes it instantly recognizable.
Execution Tips：
Avoid regrips by aligning U beforehand; use your left index for quick U pushes.
