Fridrich method (modified) (part 2)



2. Placing of the first layer corners

The aim is to place correctly the corners containing the white colour, to complete the white face and to create some T in the vertical faces (Figure 2):

Hold the cube with a face in front of you; if the piece of the right upper corner contains a white sticker, there are two cases: the piece is the one which should be in that position (piece well posisitioned; Table 3), or should not be in that position (piece badly positioned; Table 4).

This can be used when the left upper corner contains a white sticker. There are too cases, too (piece well positioned; Table 5, or piece badly posotioned; Table 6]).

The cases in which the corner is on the left (Tables 5 and 6) can be replaced by those in which the corner ends up on the right (Tables 3 and 4) with just a turn of the whole cube. Although they are explained here so that this guide is more complete and to avoid turning the cube, right-handed people may prefer the movements described in Tables 3 and 4, and left-handed may prefer those of Tables 5 and 6.
