OLL14 (Knight Moves shape)

(r’ U r) U (r’ U’ r) (f R’ f’) (horizontal center line & colored ULB)

(R’ F R) U (R’ F’ R) (F U’ F’) (horizontal center line & colored UFR)

R’ F R move is Sledgehammer without last F’. For R’ F’ R move, it is better to use left-index-finger F’ (Michael Trigger).

For F U’ F’, I use my right thumb to move F-face down and up. using right index finger and thumb to move it down and up may be the normal style, but this needs regrip.
