Nimzowitsch Defense: Colorado Countergambit
Overview
Nimzowitsch Defense: Colorado Countergambit is a sacrificial opening line filed under ECO B00 in the Semi-Open Games group. The defining idea is the early concession of material to seize the initiative and unbalance the position.
The Semi-Open Games group covers semi-open games — replies to 1.e4 where Black declines the symmetrical 1…e5 in favour of an asymmetric pawn structure.
It begins with 4 plies and takes 1. e4 Nc6 2. Nf3 f5 to reach the canonical position.
In the opening tree, this line branches off from Nimzowitsch Defense: Declined Variation, part of the broader King's Pawn Game system.
It continues primarily into one named line, Nimzowitsch Defense: Colorado Countergambit Accepted.
