There are so many algorithms that maybe it would be a better use of the time to practice other aspects. It would take too long to memorize every single one of them.
For K1 cases, I find it easier to locate where the two 3-sticker checker pattern blocks are. Then, move those to the F and BR faces to setup the angle. If the checker is on the right side, it's the R2' alg, if it's on the left side it's the R2 alg.
