Easy Cases

The Pair

F2L01.png F2L02.png

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

Speedsolving Logo tiny.gif F2L U' (F' U F)


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.

Speedsolving Logo tiny.gif F2L R U R'


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.

Speedsolving Logo tiny.gif F2L U' R U R' . U2 (R U' R')
Speedsolving Logo tiny.gif F2L U F' U' F . U2' (F' U F)


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' R U2 R' . U2 (R U' R')
Speedsolving Logo tiny.gif F2L U F' U2' F . U2' (F' U F)


Becomes The Pair.

Reposition Edge and Flip Corner

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 R' . U (R U R')


Becomes Split Pair.

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

Twisted Pair

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.

F2L11.png F2L12.png

Speedsolving Logo tiny.gif F2L U' R U2 R' . U (F' U' F)
Speedsolving Logo tiny.gif F2L U F' U2' F . U' (R U R')


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.

Back right slot open : R' U R F' U' F

Speedsolving Logo tiny.gif F2L U' R U' R' . U (R U R')


Becomes Split Pair.

Split Pair by Going Over

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 F . U2' (R U R')

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' R' . U2 (F' U' F)


Becomes Split Pair.

Dead Twisted Pair

F2L17.png F2L18.png

Front half faces upward with sides of opposite colors to cube; back half attached on its own side and oppositely colored to the front.

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