for 5:40: can´t you do just the setup move U? than it would be again the first case

[kinch2002]

@ottithecube Yes you could, and it would be 10 moves to solve it. I was showing how you can do comms with the interchange move first so that it's still 8 moves

what about a piece on a U face needs to go to a piece on the F face which needs to go back to the U face?

[kinch2002]

@huntforfood99 I have a 'face-interchange comm' video to explain that

Great tutorial!

Thanks for this tutorial!

Hope I can solve the 4x4 BLD soon!

For the 2nd commutator in your example solve, you could just do [r, Uw' l Uw]

@kinch2002 thanks.

@TheMachanga It doesn't matter if the buffer is one of the opposite pieces. As long as you do the 3-cycle, you'll solve the 2 pieces you're trying to.

U face to B face to D face: D to U with f2 or b2 will be the interchange as those are opposite, and D belongs in U. So set up those two e.g. Dbr and Ubl are interchangeable with b2. Then Dbr would be the action spot, so something like r' B2 r b2 r' B2 r b2 would cycle Ubl to Bdl to Dbr.

Similar to the vid example but with an x/x' cube rotation

@kinch2002 Thanks about the 2 switch, but you didn't answer the first question. I know how to solve it if the buffer is on U and the opposite are F and B, but what if a piece is opposite of the buffer? (3 cycle, not 2 center switching)
