DBB

The DBB Method: This method consists of creating a bar of edges on the d face matching with 2 centres on opposite sides (left and right). This is called DB or Down Bar. Then create a bar connecting the 2 centres but on the back. This is called BB or Back Bar. You will then do a D2 and put the other pieces of the 2x3x3 block into that open space at the front. This is known as L3P or Last 3 Pieces. You then do another D2 to align the bottom layer. Then you insert the remaining edge on the front, and then the last 2 pairs. This is known as FFB or Finish Front Block. You then do OLL and PLL.
