Recently I have been trying to do better in F2L, and I have come up with a new idea. I got some inspiration from when I learned BLD.
I used Speffs cubing notation: bit.ly/SpeffzNotation.
So every case has a name of this format: "X-YY" where X is a number and Y is a letter.
Number, or X
Let's take the number first. In my model the number one stands for the pair in the front right, no matter how the cube is turned.
Here is an idea of what it might look like (And just so you know, blue is Front and red is Right):
| Number | Normal | After y2 rotation |
| 1 - Front right | | |
| 2 - Front left | | |
| 3 - Back left | | |
| 4 - Back right | | |
If you would have another colour, for example, red as Front and green as Right, the table would look like this (red is Front and green is Right):
| Number | Normal | After y2 rotation |
| 1 - FR | | |
| 2 - FL | | |
| 3 - BL | | |
| 4 - BR | | |
You can remember it as the FR pair is number 1, and then it goes clockwise as seen from above.
In other words, the number tells you the orientation to hold your cube on. If it's 1, the pair is in the FR slot, and so on.
first letter, or Y (1)
The first letter stands for the edge. But first, look at the F and B colours. The edge has a sticker that corresponds to one of those colours. That sticker is called the
heavy sticker, or the
correct sticker. If you look at Speffz notation, you can see that each sticker has a number. Notice that it is each
sticker and not each
edge. This is important as it is two different cases if the edge is flipped.
To see which edge position you have, look at where the
correct sticker is positioned. Then insert that letter into your equation.
second letter, or Y (2)
The second letter stands for where the corner is positioned. The
correct or
heavy corner piece is the bottom colour. For most people, it will be white.
The total possible cases will be 16 edge stickers in the top two layers, and 24 possible corner stickers in the whole cube, and that makes 384 cases, which is less than ZBLL. I will try and add examples during the weekend, and please tell me if you like this idea.
