Blitz blockade

The Blitz blockade in chess is a rare type of action which results in the nearly complete blockade of the opponent's forces, while leaving his king subject to attack. Such a slow-motion method can only succeed quickly if the opponent is oblivious to the threat and fails to make the required freeing moves in a timely fashion. Thus, this tactical motif is more likely to ensnare the amateur. Blockade is an important strategic concept in chess, well described by Aron Nimzowitsch in the seminal work ‘Die Blockade (The Blockade)’, whose mantra was “First restrain, then blockade, finally destroy!”[1] The importance of the blockade was formalized in Nimzowitsch's rule – Blockade every pawn that shows the slightest inclination to advance. Blockade every passed pawn, every portion of the center, every quantitative or qualitative majority.[2]
