2 Look OLL(Orientation of the Last Layer)
OLL is the last step in Fridrich method. In 2 look OLL, I've decreased the from 54 algorithms into only 9 algorithms to make it much more easier than the normal OLL. The main aim of 2 look OLL is to turn a non oriented face of the 3rd layer into a an oriented face. see under:-
Stages in 2 look OLL
There are 2 stages in 2 look OLL.
1. Solving the cross
2. then, to orient the last layer's face
Solving the 3rd Layer's cross
4 edges oriented
the cube is solved, move on to the orientations.
2 edges oriented #1
perform this algorithm: f(R U R' U') f'
2 of the edges oriented #2
perform this algorithm: F(R U R' U')F'
None of the edges oriented
perform this algorithm: F(R U R' U')F' f(R U R' U')f'
you just have to memorize the #1 & #2 algs where only 2 edges are oriented
Orienting the 3rd Layer's face.
After you have the cross, you are guaranteed to do one of this 7 algorithms.
perform this algorithm: R' U' R U' R' U2 R
perform this algorithm: R U R' U R U2 R'
perform this algorithm: F(R U R' U') (R U R' U') (R U R' U') F'
Notice that the (R U R' U') occur repeatedly.
Non Symmetry cross
perform this algorithm: f(R U R' U')f' F( R U R' U')F'
or R U2' R2' U' R2 U' R2' U2 R
perform this algorithm: R2' D R' U2 R D' R' U2 R'
perform this algorithm: (r U R' U') (r' F R F')
perform this algorithm: F'(r U R' U') (r' F R)
