How to Set Up the Pair
Before you can insert an F2L pair, you often need to
set up the corner and edge so they can be paired easily. This is the heart of intuitive F2L — learning how to move pieces into
useful positions without breaking solved slots.
1. Bring the Corner to the Top Layer
If the corner is stuck in the slot incorrectly, use a simple alg to take
it out:
- Right slot: R U R'
- Left slot: L' U' L
This removes the corner and keeps the rest of the cube the same.
2. Separate the Corner and Edge
If the corner and edge are grouped together in a bad way, break them
apart using:
- Right side: R U R'
- Left side: L' U' L
After separating them, place both pieces in the top layer where you can
pair them up.
3. Position the Corner Correctly
Rotate the top layer until the corner is above the slot it needs to go
to. The white sticker should face either:
- Front → easy to pair
- Right → use right-hand pairing
- Left → use left-hand pairing
-
Up → requires reorientation and usage of an alg
4. Position the Edge Relative to the Corner
The edge should be placed in one of two positions:
- To the right of the corner → use U R U' R'
- To the left of the corner → use U' L' U L
These moves pair the pieces without disturbing other slots.
5. Form the Pair
Once the corner and edge are aligned, use a simple alg to pair them up:
- Right pairing: U R U' R'
- Left pairing: U' L' U L
6. Insert the Pair
With the pair formed, insert it into the slot:
- Right insert: R U R'
- Left insert: L' U' L
