The Queen's Indian Defense: Buerger Variation is a strategic chess opening that focuses on solid development and control of the center.

The Queen's Indian Defense: Buerger Variation is a popular opening choice for Black that arises after the moves 1. d4 Nf6 2. c4 e6 3. Nf3 b6. Black's idea is to establish a strong presence in the center while maintaining flexibility in piece development.

After 4. g3, White aims to control the center with the fianchetto setup, preparing to develop the bishop to g2. In response, Black plays 4...Bb7, developing the bishop to its most active square and putting pressure on the e4 pawn.

White often continues with 5. Bg2, completing the fianchetto setup and reinforcing the center. Black then plays 5...c5, challenging White's central pawn structure and aiming to open up lines for their pieces.

The move 6. d5 is a key move in the Buerger Variation, where White aims to break open the center and create imbalances. Black has two main options here: capturing on d5 or playing 6...exd5.

If Black captures on d5, White responds with 7. Nh4, attacking the knight on f6 and preparing to recapture the pawn on d5 with the knight. Black can choose to defend the knight or exchange it, leading to different pawn structures and piece placements.

Alternatively, if Black plays 6...exd5, White can play 7. Ng5, targeting the knight on f6 and creating threats against Black's position. Black has to decide how to deal with this pressure, either by defending the knight or exchanging it.
