OLL38 (W shape)

(R U R’ U) (R U’ R’ U’) (R’ F R F’) (W shape stuck to left back corner)

(R U R’ U) (F’ U F) U2′ (R U’ R’) (W shape stuck to front right corner)

The second one has F’ U F sequence which I personally dislike. I try to use my left index finger and left thumb, or only left thumb for it, but am not good at it.

So, when U/U’ precedes F’ U F, and the trailing moves don’t become so complicated, I prefer avoiding that, using d/d’ turn.

My version is as follows.

(R U R’) d (R’ U R) U2′ (f R’ f’)

Finger trick: first U by left index finger (pushing), d by right thumb
