A category of block not physically related, but otherwise distinguishable by not fitting into any of the other category of block.

Comments:

Specialized blocks should be looked at as a collection of unrelated blocks that do not fit into other categories of blocks.

The one element these maneuvers have in common is that they employ at least two (2) different forms of blocking to be enacted.

Derivation:

Specialized - meaning special or out of the ordinary.
