Two-look OLL

The whole yellow face in two algorithms: first the cross, then the corners.

Goal of this step

After F2L, only the last layer remains. OLL makes the whole top face yellow. In the two-look version, it is split into two steps:

the yellow cross: 3 cases (line, L, dot), with algorithms close to the beginner method. Here, the L case is held front-right with f R U R' U' f', whereas the beginner method held it back-left with F U R U' R' F': both are correct, they are simply different algorithms;
the yellow corners: 7 cases, each solved by a single algorithm, instead of repeating R’ D’ R D corner by corner.

To recognize a corner case, look at the yellow stickers on the sides of the top layer, not only on top. The “goal” cube above shows the result: the whole yellow face is done, but the pieces are not in place yet.

Cases and algorithms

Yellow cross, line: hold it horizontally.

F R U R' U' F'

Yellow cross, L: point its two arms to the front and to the right.

f R U R' U' f'

Yellow cross, dot: chain both algorithms.

F R U R' U' F' f R U R' U' f'

Sune: a single yellow corner on top, front left; the front-right corner faces forward.

R U R' U R U2 R'

Anti-Sune: a single yellow corner on top, back right; the front-left corner faces forward.

R U2 R' U' R U' R'

H: no yellow corner on top; two yellows on the left and two on the right.

R U R' U R U' R' U R U2 R'

Pi: no yellow corner on top; two yellows on the left face, one at the front, one at the back.

R U2 R2 U' R2 U' R2 U2 R

Headlights: both back corners are yellow on top; the front ones have their yellow facing forward.

R2 D R' U2 R D' R' U2 R'

T: both right corners are yellow on top; the left ones face forward and backward.

r U R' U' r' F R F'

Bowtie: two yellow corners diagonally; the front-right corner has its yellow facing forward.

Tips

To recognize a corner case, first count the corners already yellow on top: 0 (H or Pi), 1 (Sune or Anti-Sune) or 2 (Headlights, T or Bowtie).
Turn U (U, U' or U2) before the algorithm to hold the case exactly as in the animation: that is the AUF (Adjust U Face).
Sune and Anti-Sune are short and show up everywhere (they are reused in other methods): learn them first.
