u2 method

Hello speedsolving forum. I was watching this video. In it stanley describes some bigBLD center tips for U2 method. I've practiced and successfully implemented for X-centers. But, I can't seem to figure out the method for +-centers. It isn't explained in the video, the only thing stanley...

U2 was made by Orozco since 11 years ago, but in this moment there were inneficient algorithm. The idea behind U2 is to use it as a "Base method", with UF/UFR as the buffers, the mechanism is the same than M2 and R2,. Corners (Speffz) A: U2 B: [l' R' : [D2, R U R']] + U2 C: Buffer D: [R' D R...

I stumbled across an old thread talking about U2, an improvement to R2, which you all know is generally regarded as bad. The idea is similar, but you setup to UFR and use U2 to swap with UBL buffer instead. The problems with the older thread: Parity sucked Special cases sucked So I have...

this method is basically improvised R2 and it uses the same idea. buffer:ULB helper:URF idea is to insert the target at URF and do U2 and undo the insertion.therefore in the form of ABA'.\ note:when executing U2 UBR and UFL gets switched. Setup list Normal cases DFR...
