Base Cases

The Pair

F2L01.png F2L02.png

Move the pair forward, then make room and slot it in.

Split Pair

F2L03.png F2L04.png

Front half faces forward, would be correctly placed by turning downward. Back half is parallel to forward direction and oppositely colored.

Bring the pair together, then move it forward and return.

Reposition Edge

Twisted Split Pair, Perpendicular

F2L05.png F2L06.png

Front half faces forward, back half lies perpendicular and is similarly colored.

Move backward, then hide the front half in the corner and move the back half in to make the pair.

Becomes The Pair.

Twisted Split Pair, Parallel

F2L07.png F2L08.png

Front half faces forward, back half lies parallel and is similarly colored.

Move backward, then hide the front half in the corner and move the back half in (by a half-turn) to make the pair.

Speedsolving Logo tiny.gif F2L U [F': U2' . U2' [F': U]]


Becomes The Pair.

Reposition Edge and Flip Corner

These involve a quarter-turn if the white face of the front half faces down when hidden in the corner, and a half-turn if it faces to the side.

Mnemonic: The white face is a foot dragging behind, slowing rotation down to a quarter-turn.

Crossed Split Pair

F2L09.png F2L10.png

Split pair, but back half lies perpendicular.

Move forward, then hide the front in the corner, then move the back half into position for the split pair.

Speedsolving Logo tiny.gif F2L U' [R: U . U [R: U])]


Becomes Split Pair.

Back Right Slot Open: R' U R2 U R'

Twisted Pair

F2L11.png F2L12.png

Pair, but the back half is twisted.

Move backward, then hide the front half in the corner and move the back half into position (by a half-turn) for a split pair.

Speedsolving Logo tiny.gif F2L U' [R: U2 . U [F': U']]
Speedsolving Logo tiny.gif F2L U [F': U2' . U' [R: U]]


Becomes Split Pair.

Back right slot open: R' U2 R2 U R'

Twisted Sideways Pair

F2L13.png F2L14.png

Front half faces sideways, back half oppositely colored. Each side faces "correctly."

Move backward, hide the front half in the corner, and position the back half for a split pair.

Speedsolving Logo tiny.gif F2L U [F': U . U' [F': U']]


Back right slot open : R' U R F' U' F

Speedsolving Logo tiny.gif F2L U' [R: U' . U [R: U]]


Becomes Split Pair.

Split Pair by Going Over

These have an opposite pattern to the above: If the white face is down, it's a half-turn.

Mnemonic: Each of these is a “slingshot”; flinging something sideways (i.e. the front, or white part, isn't forward) won't send it as far.

Sideways Pair

F2L15.png F2L16.png

Front half faces sideways, back half similarly colored (on top).

Lean back, then move backward to cut. Return, forming a split pair.

Speedsolving Logo tiny.gif F2L [F': U . U2' [R: U]]

Front left slot open: U (R U' R') D (R U' R') D'

Back right slot open: U' (R' U R U') (R U R')

Speedsolving Logo tiny.gif F2L [R: U' . U2 [F': U']]


Becomes Split Pair.

Dead Twisted Pair

F2L17.png F2L18.png

Front half faces upward, back half attached on its own side and oppositely colored.

Lean back, then move backward a half-turn to cut. Return, forming a split pair.

Speedsolving Logo tiny.gif F2L [F': U2' . U [F': U']]


Becomes Split Pair.

Pair Made on Side

Dead Split Pair, Back Opposite

F2L19.png F2L20.png

Front half faces upward, back half is opposite its top color.

Move the back half to its own color, hide it in the far corner, then move the top half to make the pair.

Speedsolving Logo tiny.gif F2L U [R: U2' . U [R: U']]
Speedsolving Logo tiny.gif F2L U' [F': U2 . U' [F': U]]


Becomes The Pair.

Dead Split Pair, Back Adjacent

F2L21.png F2L22.png

Front half faces upward, back half is near its top color.

Rotate the front half parallel to the back half. Clear that face, then return, forming a split pair.

Speedsolving Logo tiny.gif F2L [F': U . U2 [F': U']]


Becomes Split Pair.

Weird

Dead Pair

F2L23.png F2L24.png

Front half faces upward, back half attached and similarly colored (on the front).

Just … just do as the man says.

Becomes Split Pair.

Corner in Place, Edge in U Face

Prodigal Son

F2L25.png F2L26.png

Front half is correct; back half is on the side matching its outward color.

Move the back half away, flip the front half up, then return the back half and bring together the pair.

If the back right slot is open:

Becomes The Pair.

Posing Outward

F2L27.png F2L28.png

Back half is on its own side; front half is in place but facing the other side.

Hide the back half in the corner, then bring the front half toward it to make the pair in the corner.

Speedsolving Logo tiny.gif F2L [F': U . U' [F': U])]


Becomes The Pair.

Posing Forward

F2L29.png F2L30.png

Back half is on its own side; front half is in place but facing that same side.

Hide the back half in the far corner, move the front half away, then restore to form a split pair.
