Eponymic openings and counter-gambit, system 

👇

In almost 20 years of constant practical studies on the D: 20 Lady's gambit accepted, I had the opportunity to create and design an experiment in more than 170 countries and also in my home country, to play more than 10,000 chess games against my opponents, understand the lines and systems of open, closed and semi-open and semi-closed openings, refused and deferred openings, accelerated or declined attacks, passive movements, mastering the advantage of space in the center of the board and much more than complex in its development and context. My games took place through clubs, tournaments, video conferencing, classical chess, (tangible), tactile board games and online at sites mainly playchess.com, chess.com, kurnik.

In a period of 2 years analyzing chess engines or infinite analysis of chess machines only 40 lines my opponents will use external sources in the case of chess programs. But the result of my experiment was spectacular. I found 20 new lines and techniques in their development and they were never mentioned behind the scenes of chess or for purposes of objects of study as teaching and learning bases or as references of model games or base game interpreted by a Great Professional Titled Master of FIDE. These are the first evolutionary openings or naming systems in chess. I deepmindchess became an expert. The lines and system are posted at the bottom of the page in chess diagram or in algebraic writing and notation.

Pawn positioning is a key element in chess strategy due to their low mobility which creates permanent weaknesses in the pawn chain. They are used to control important squares on the board or to prevent the advance of opposing pawns. When the path is clear, the advance of the pawn on the board increases the probability of promotion to Queen, which can influence the strategy to be adopted as the opponent moves his pieces to block the pawn. On the other hand, the pawn's advance also weakens the defenses themselves by the pawn's impossibility to retreat and defend such positions. Context taken from source: Wikipedia
