ZBLL AS

ZBLL AS: one corner oriented; with it at the front left, the front-right corner shows the top colour on the right.

What it is

ZBLL solves the whole last layer in one algorithm once its edges are oriented, as they always are after ZZ's EOLine or a ZBLS/VHLS last slot. There are 493 cases: 472 in seven subsets named after the corner-orientation shape (T, U, L, H, Pi, S, AS), plus the 21 PLLs.

Each subset is 72 cases (H is 40): the corner shape fixes the subset; within it, cases split by the corner permutation (the COLL case) and then by the edges. Most solvers learn ZBLL subset by subset, often starting with T and U, which are the most common and the most regular.

Recognition

Identify the corner shape first (it names the subset), then the COLL case from the corner stickers, then the edges: look for blocks and headlights on the sides, and where the edge matching a headlight pair sits.
