I know two OLL parity algs while the first one swaps the front two corners and two edges like an F-perm(the alg which most people use-r U2 x r U2...) and flips the dedge, the second alg swaps only the two corners and flips the dedge . So if I have OLL parity, I will do one of the two algs.If I can predict that I have PLL parity,I will do the second alg and I don't have to do the PLL parity alg . Tell me a way to predict that I have PLL parity.
ohh...I see
So as far as tutorials go, I don't know of any good ones, but jskyler wrote up a thing some time ago about this. Basically, you have to look at the permutation of the unoriented pieces and determine whether it looks like a PLL or not. Without parity, even unoriented pieces should still be permuted in a pattern similar to a PLL case.
