2x2 — Ortega
1. Solve one side (intuitive). 2. Orient the other side's corners (OLL). 3. Permute both layers (PBL).
OLL — orient the second side
The 7 corner-orientation shapes — several are the same algorithms as CFOP's 2-look OLL.
PBL — permute both layers
Bottom layer is drawn as if you flipped the cube over sideways — the front stays at the bottom of the picture.
