The 1x2x3 Block is the first step of several 3x3x3 speedsolving methods, the most popular being Roux. This first step consists of building a 1x2x3 block anywhere on the cube.

Depending on the method used, it may also be called First block (often shortened to FB) in a Roux context or Left block (shortened to LB) in a LEOR context.
