This algorithm is one of the essential OLL cases. It helps you orient the last layer more efficiently.
About This Case：
OLL19 resembles a nearly finished cross with twisted corners. It's one of the most balanced OLL cases.
Recognition：
The top looks like a yellow cross, but the corners are incorrectly oriented.
Memory Hint：
If you see a cross with twisted corners, it's either OLL19 or 20—check the symmetry to confirm.
Execution Tips：
Master M-layer finger tricks; M/U combos appear often in cases like this.
