Step 2: How to solve the white corners in the first layer
Finishing the first layer of the Rubik's Cube is not a big deal. Just like in the previous step, the white corners can be easily completed by an average people intuitively after a short familiarization with the cube.
The second step of the beginner's Rubik's Cube tutorial doesn't require long algorithms. You just have to apply a couple of short permutations which you don't even have to memorize.
Some example tricks
Here are a few examples which you might be facing while solving your Rubik's Cube when you want to move a white corner piece to the top layer. In each example the piece we're fixing is the last white corner to demonstrate that these moves don't break the solved pieces.
According to the orientation there are three cases:
White sticker facing to the right.
White sticker in the front face.
White sticker at the bottom of the cube.
When the white corner piece is in the white layer just in a wrong spot you first need to take it out to the bottom layer and do one of the previous moves. An example:
Using only one algorithm: R' D' R D
There's an algorithm which works all the time in every cases. The bad thing is that it's longer than the optimal moves.
If you have already read this tutorial then it might be familiar from the last step when we're completing the yellow layer corners.
Let's say we want to bring a white corner piece to the front-right-up position. The idea is to move the corresponding corner piece below this spot, move the corner piece in question to the front-right-down spot and do the R' D' R D algorighm until the cubelet will fit in the white layer.
Depending of the initial orientation you'll have to perform this permutation...
