The Blockade Benoni is a setup for Black that always involves the creation of the pawn formation c5,d6, and e5 against the corresponding c4,d5, and e4 pawn triangle for White. White has more space, but Black will try to use the locked nature of the center to conduct a King side attack not completely different than what a Kings Indian Player typically enjoys. I believe this pawn configuration is also called the Schmid Benoni. Black will frequently maneuver a Knight to f4.
In the following game played at the Internet Chess Club, White ended up placing his Bishop at f1, hoping to defend against possible sacrifices at h3 involving the nice coordination between the c8 Bishop and the f4 Horse. White pried open the b-file and played on the Queen Side.
