Black's Main Responses
Breaking the Pin

Solid Development
Black develops solidly and prepares queenside expansion to create counterplay.
Central Strike
Immediate central action, seeking to disrupt White's setup and gain active piece play.
Understanding the Pin
The Bg5 pin is a classical motif in chess. White creates immediate tactical threats while maintaining good development. Black must decide whether to break the pin immediately with ...h6 or tolerate it while creating counterplay elsewhere.
Key Strategic Themes
For White
- Maintain the pin: Keep pressure on the f6 knight
- Central dominance: Use the strong pawn center effectively
- Tactical awareness: Look for tactics based on the pin
- Development tempo: Complete development quickly
For Black
- Resolve the pin: Decide when and how to deal with Bg5
- Create counterplay: Don't remain passive under pressure
- Central activity: Use ...c5 or ...e5 breaks when appropriate
- Piece coordination: Develop pieces to active squares
Typical Plans and Ideas
White's Follow-up
White often castles queenside and launches a kingside attack, maintaining the pin pressure.
Black's Counterplay
Black develops actively on the queenside, seeking counterplay against White's potentially exposed king.
Important Considerations
For White: Don't become too focused on the pin. Central control and development are equally important.
For Black: Breaking the pin with ...h6 weakens the kingside, so consider the timing carefully.
Modern Practice
The Byrnes Variation remains a solid choice for players who want straightforward development with immediate pressure. While not as theoretically challenging as the Austrian Attack, it offers good practical chances and is easier to play in practical games.
