This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL13 is a Knight Move case where the yellows form a diagonal L-shape with an extra corner attached.
Recognition：
Three yellows align diagonally, with one more sticking out like a knight move in chess.
Memory Hint：
Trace the diagonal L first, then note the extra sticker. This two-part recognition is very fast.
Execution Tips：
Avoid unnecessary regrips—adjust U beforehand for a comfortable orientation.
