Step 2 of 6

Second block

What you should end up with

A matching 1×2×3 block on the right. The middle slice between the blocks stays free: it will come in handy.

How to do it

Hold the first block in your left hand and do not break it. So only R, r, U and M work here, with no D, F, B or L.
Do not rotate the cube. These four moves can bring you everything you need.
First place the bottom edge. Then build the two corner-edge pairs, front and back, in any order.
A pair goes in with three moves: R or r opens the front slot, U brings the pair in, and R' closes the slot. The back slot is the other way round: R' or r', then U, then R.

The bottom edge

On top, white up Turn the top so the edge is on the right and do R2.

U' R2

In the middle slice, white to the side M or M' lifts the edge with white up. Then as in the case above.

M' U R2

At the top right, white to the right U' takes the edge into the middle slice, and M flips it. Then as usual.

U' M U' R2

In the right middle layer, white to the front The edge is already in the R layer: R' puts it in place. If it is at the back with white to the back, use R.

R'

In place, but flipped The longest case. Bring the edge to the middle slice, let M flip it, then put it back.

R2 U M' U R2

Inserting at the front: three moves

The pair on top The corner is at the top front left, white facing left. The edge is at the top front, next to it.

R U' R'

The edge at the back The corner is at the top front right, white facing right. The edge is at the top back.

R U R'

The edge at the front, with a wide move The corner is at the top front right, white facing right. The edge is at the top front. The wide r forms the pair and starts the insert in one move.

r U R'

The edge on the bottom, with a wide move The corner is at the top front left, white facing left. The edge is at the bottom front, in the middle slice. The wide r lifts it to the corner.

r U' R'

Inserting at the back: the same, mirrored

The pair on top The corner is at the top back left, white facing left. The edge is at the top back, next to it.

R' U R

The edge at the front The corner is at the top back right, white facing right. The edge is at the top front.

R' U' R

The edge at the back, with a wide move The corner is at the top back right, white facing right. The edge is at the top back.

r' U' R

The edge on the bottom, with a wide move The corner is at the top back left, white facing left. The edge is at the bottom back, in the middle slice.

r' U R

If the pair is not formed yet

A whole back pair The edge is at the bottom front, in the middle slice. U2 M' U2 lifts it and places it next to the corner. r' U' r inserts the pair.

U2 M' U2 r' U' r

A whole front pair The edge is at the bottom front and flipped. M flips it while the corner is out of the way. Then the pair forms and goes in.

R U M' U R' U' r U r'

Tips

›A first target: the second block in under 22 moves. Then under 19. Experienced solvers need under 16.

›An edge flips only with M, and it enters or leaves the middle slice only with U. That explains nearly every case.
