Mirrored Inverse Sexy Method (MirIS)

[Cride5]

Hi BirdOfChaos, welcome to SpeedSolving community.

Glad you managed to get back into cubing with MirIS.

The '3 slots' step of MirIS is basically a restricted version of the F2L step in CFOP. If you use the technique to fill up 4 slots instead of 3 you are onto a normal CFOP last layer.

To progress from MirIS to CFOP I'd recommend doing the following:
1. Combining daisy and cross into a single step
2. Filling the 4th slot and learning learning 4-look last layer
3. Learning shorter sequences for inserting corner/edge pairs during F2L, start by looking for tutorials on intuitive F2L
4. Progressing onto 3-look and then 2-look last layer

Thanks Cride5!

First of all, thank you for developing this method and tutorial. It's easy to remember once you understand it.

After several hour of missteps, I finally got the algorithm to work! And I think I finally understand it. There were a few places where I had difficulty: In building the F2L, the tutorial says "Now hold the cube so that the edge is facing you." It think it would be better to have said "Now hold the cube with the vertical stripe facing you." I held the cube at 45 degrees and left and right of the edge were not clear.

A second point of confusion concerned building the yellow cross when the edge wasn't in the keyhole. In one case it was in the middle layer back right, ind doing IS did not budge it. I wound up moving the keyhole and things worked OK after that.

My final Ah-Ha was realizing during the solution of the five corners, that the two non-yellow corners needed to match the two center (and bottom tiles) on the faces that met at the corner. Not only that, but the tile was properly positioned when the tile matched the color of the tile to its left. When positioned correctly, a new bottom corner can be chosen: if the top tile has a yellow face, match the bottom corner to the tile and move it into place; if the tile on top has a white face, move an unsolved corner into place and do an IS to move it to the top. Then move the matching corner into place (if necessary).
