Sokolsky/Polish Opening (1.b4) - Symmetrical Variation

>>Main article: Sokolsky/Polish Opening (1.b4). Basic Opening Theory.<<

After 1. b4 Black can answer symmetrically with 1... b5blocking White's b-pawn and preparing to fianchetto his light-squared bishop. 

The Symmetrical Variation is a very rare defense which proves its unsoundness as a response to the Sokolsky.

There are three major continuations for White: 2. a4, 2. Bb2 and 2. e3. All these moves lead to a better position for White. 

I. 2. a4 - the most aggressive choice:

II. 2. Bb2:

III. 2. e3:

It seems that 2. a4 is the most vigorous way to deal with the Symmetrical Variation.
