I have been using yau now and I use 3-2-3 pairing. Only sometimes I end up with a case where I end up with 2 unsolved edges(4 pieces in total) lets say the blue red edge and the blue orange edge. But the blue red piece is next to the blue orange piece, and ofcourse the other blue red piece is also next to the blue orange piece, so I have 2 incorrect pairs, how do you solve that, I could place them with their same color in their mutal face and do d R F' U R' F d' but that messes up the cross. Any efficient solutions?
