Opening Name: Queen's Gambit Declined: 3.Nc3 Bb4

Moves: 1. d4 d5 2. c4 e6 3. Nc3 Bb4

Description: The move 3...Bb4 in the Queen's Gambit Declined introduces the Ragozin Variation. Black pins White's knight on c3, increasing pressure on the center and indirectly challenging White's control over the d4 and c4 squares. This pin is a characteristic feature of this line, aiming to create tension early and provoke structural or developmental concessions from White.

Characteristic: The main characteristic of 3...Bb4 is the pin of the knight on c3, which supports Black’s strategic goal of controlling the center and restricting White's natural development.

Strategic Nature: For Black, this move is somewhat both defensive and attacking. It is defensive in the sense that Black solidifies the center with e6 and prepares to challenge White’s center, but also attacking by applying immediate pressure on White’s knight and indirectly on the central squares. For White, the position remains dynamically balanced, with possibilities to challenge Black’s setup actively.

Center Control: This opening aims to contest the center rather than ignore it. Black’s Bb4 exerts pressure on White’s knight that supports the center, helping Black to undermine White's central dominance. White typically responds by maintaining or reinforcing central presence, so the battle for the center is an essential theme here.
