Trigo - Modernized Philidor Defense

Trigo - Modernized Philidor Defense. Livre en anglais sur la défense Philidor. “Pawns are the soul of chess.” We have all heard this phrase more than once in our chess life and we owe it to the great French player François-André Danican, so-called Philidor, considered one of the best chess players of the 18th century.
It’s not surprising that with this way of thinking, he revolutionized chess, which until then was almost all about direct attacks on the king. With this, he also changed the way of understanding and playing openings, in which he introduced a new concept for the time – that the pawns should be ahead of the pieces.
Bearing this in mind, the defense he created can be much better understood, in which all these rules are fulfilled and the importance of the pawn structure is maximal.
