The St. George Defense is a unique and somewhat unconventional opening that begins with the move 1…a6.
It’s a provocative approach, with a distinctive game plan and underlying strategy.
Here we’ll look at the St. George Defense in depth, discussing the move order, the theory and strategy behind the opening, its variations, historical significance, suitability for different skill levels, and its prevalence at the grandmaster level.
Move Order of the St. George Defense
The St. George Defense starts with the moves 1. e4 a6.
The move 1…a6 may look mysterious, but it is part of a broader strategy.
Black’s intention is to prepare a queenside advance with 2…b5.
This can prevent early bishop or knight penetration.
This opening sequence allows White to occupy the center with 2.d4.
Theory, Strategy, and Purpose of the St. George Defense
The primary purpose of 1…a6 is to prepare the move 2…b5, a queenside pawn advance.
This approach challenges traditional opening principles that emphasize control of the center.
By allowing White to establish central control, Black aims to induce overextension and create counterattacking opportunities later.
Black’s strategy may also include fianchettoing the queenside bishop and developing pieces behind the pawn structure.
Evaluation of the St. George Defense
The St. George Defense is evaluated at approximately +0.60 to +0.80, favoring a white advantage.
However, black has the advantage of not going down well-trodden theoretical paths.
Variations of the St. George Defense
There are several ways the game can continue after the initial moves, leading to different variations.
The most common White response is 2. d4, taking advantage of the opportunity to occupy the center.
White can also choose to play more cautiously with moves like 2. Nc3 or 2. Nf3.
Black’s plans can vary as well, including the immediate 2…b5 or developing pieces before launching the pawn advance.
