Hi, Rouxers)
I have a problem for 4b - 4c look-ahead in one case. I will try to describe..
For example scramble:
M U2 M' U' M U2 M'

Front is orange at picture.
I know how solve it if I memorize DF stiker (on D).
1) I memorize DF sticker;
3) M U2 M'
4) I do: U or U' in situation: if UL = DF(1step) i do U and if UR = DF(1step) i do U')
This method viewed in 4b-4c video from PandaCuber and it cool, but i dont understand how do it if in my case dont see at DF sticker?
I only interested in case when F - stikers at FUL and FUR are same color, but FU is opposite color.
If I have this case:
M U2 M' U' M U2 M

i solve it memorize UB (on U):
1) I memorize UB sticker;
3) M' U2 M'
4) I do: U or U' in situation: if UL = UB(1step) i do U and if UR = UB(1step) i do U')
.. it better, and I know how to solve it quickly without D-stickers
How solve 4b-4c (LSE) with look-ahead in first case if I dont know DF sticker? I without M2))
I hope for your help and the fact that I was able obesnit my problem =))
