A clear case of how naming something gives you power over it!

Yeah, it may be the only thing to keep you from suing me for plagiarism! 😏

The move ...b6 is also a pawn lever, with the leverage applied at the head of the pawn chain instead of the base.

This is a very nice elaboration of the topic, as attacking at the head of the chain is not considered as often, but can be very effective- as you demonstrated!
