This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL23 is a 'one missing sticker' full-yellow pattern. Easy to recognize once you know the group.
Recognition：
Almost fully yellow top except for a single missing piece.
Memory Hint：
If only one corner is white, it's almost always OLL23.
Execution Tips：
Reconfirm the missing sticker position—this avoids confusing it with 24.
