Edge pairing

In Yau, after solving the centres and three cross edges, you pair the remaining edges (dedges) with the 3-2-3 method.

1. Hold the cross on the bottom and the unfinished part of the cross in front. You pair the last cross edge together with the first pairs.

2. Round “3”: set up three pairs of wings so that one slice move (Uw or Dw) joins them all at once, then move the slice back, replacing the joined pairs with unjoined ones.

3. Round “2” and the final “3”: the same for the next pairs. When two wings are in the same slice, flip one with the flip alg (below).

4. When all edges are paired, insert the last cross edge and continue like a 3x3.
