The L shape, pictured left, builds off the I shape by forming another split two using one of the stones from the I shape and forming an L shape. The L shape is protected from capture because of its utilization of stretch twos, but it also has more potential for threats than the I shape. The I shape can be blocked from forming an open tria by placing a stone inbetween it, however if the opponent tries to do the same with the L shape, then the player who formed can immediately use the stretch two not blocked to form an open tria in two different ways forcing the opponent to respond.
