3 out of the last 5

Positioning of 3 out of the last 5 corners

The 'workbench' is the place where we have been accumulating the side effects of the rotations we performed to solve the cube. Now that the cubies outside the workbench are finished, it would become particularly challenging to place the last 5 corners.

However, again, a tough problem (like for the 'Tutorial.Y.The Trap' ) is matched by a very simple solution: just change the old workbench and use this new workbench instead.

The change of the 'workbench' will not affect the 5 cubies already sorted on the White face: OWB, WB, RW, RWG, RB, if we care to always use the same 'sledgehammer' (or its reverse)

To be more precise, the cubies will be affected. But at the end, every thing will be automatically sorted correctly by the cube itself.

The overall strategy is quite straightforward: swap the corners in the rdf and ruf positions by employing the 'sledgehammers' technique (R F' R' F)

Look the cubie on rdf position. Bring the cubie (on the 3rd layer) located in its destination into position ruf. Run the sledgehammer (R F' R' F) (an odd number of times) until the cubie is into its correct place and with the correct orientation.

On the other hand, if the cubie on the 3rd layer is in the right position but has the wrong orientation. Again, run the sledgehammer (R F' R' F) (an even number of times) until the cubie reach the correct orientation.

There can be 3 cases: lucky (rarely) easy standard

In this case, the final result is the cube fully solved. It is not impossible, but it is rare.

The result of this 2 cases ('easy' and 'standard') is what normally happen.

1)		Brings the destination for the RYG cubie into the 'workbench'. Then places the cubie RYG into its place
2)	3 3 times	Brings the destination for the RYB cubie into the 'workbench'. Then places the cubie RYB into its place
3)	2 2 times	The cubie OYB is already in the correct position. Needs just to change orientation.
4)		Ends the task.


1)		Brings the RY cubie to its correct position. (Read the comment) The rule of thumb to chose the second 'sledgehammer' is simple: The second 'sledgehammer' is the one that: - starts with the move that put 2 stickers in the right place. (in this example the rotation U' puts the Red sticker on the red face and the Yellow sticker on the Yellow face) - The second move puts just one sticker on the right face (in this example the rotation R brings the yellow sticker of the cubie YB on the yellow face. Attention: - There are two 'sledgehammer' that satisfies the first condition. - Only one satisfies both the conditions.
2)	2 2 times	Brings the YB cubie to the place occupied by the RY.

The 'sledgehammer' (R F' R' F) would be sufficient to solve this step. In some cases, however, it may be necessary to execute it more than three times in a row. In such cases, it is advisable to use its 'reverse' (F' R F R') Due to the cyclicity property, 5 iterations of the first sledgehammer are equivalent to a single rotation of its reverse.
