It means it's like a setup move, and it's not really part of the algorithm, so you can avoid the D2 by recognizing the case and starting out with the corner in the back.
So, if you realize you have this case, and the corner is on the right-down-back, you can do D R' D B' D' B D' R, instead of D' D2 R' D B' D' B D' R I would suggest doing F2L with the cross on the bottom, though, and for this case doing (R U R' U')*3 or something similar --- In [email protected], jarcaube <[EMAIL PROTECTED]> wrote: > > what does the brackets mean? > eg [D2] R' D B' D' B D' R > this is taken from http://www.ws.binghamton.edu/fridrich/Mike/middle.html > 5a > Yahoo!
