I saw this solution on some website but the person that wrote it didn't mention what method he used. It looks quite interesting. Which method is this:

Scramble: B2 F U R U F2 R2 F U2 D' F2 R' F' B2 U2 L2 B2 D' B' L B U L B' F2

Solve:
R' F' U2 F L x B' L U2 L'
U F2 U' z'
R F' U2 F R' B L U2 L' z'
R' U' R U L U L' U' L' D' x'
U2 R' U' R U' R' U R U
F U R U' R' F' U
R2 D R' U2 R D' R' U2 R' U
R' F R' B2 R F' R' B2 R2
M2 U M2 U2 M2 U M2 U

Heise F2L -> EO -> CO -> CP -> EP
