Bird Opening - 4/5..Qb6 Classical Variation
I missed my post last week, so I will do second post this week.
The common approach for White against ..Qb6 is to play c4, like ..c5 in the Nimzo-Indian (the reversed form). However, instead I have an affection for a4, protecting the bishop, with the tactical idea of a5. White's king bishop is poisoned, but a fair amount of opponents fall victim to taking the bishop.
Good Chess! Keith
