The resulting positions require precise calculation and deep positional understanding.
Key Strategic Themes
For White
- Queenside castling: 0-0-0 for maximum aggression
- Pawn storm: f4-f5, g4-g5, h4-h5 attacking waves
- Piece sacrifices: Often sacrifice material for attack
- Central strongpoint: Use the d5 pawn as an anchor
For Black
- Kingside attack: ...f5-f4, ...g5, ...h5 advances

Critical Variations
Queenside Castling

Kingside Castling
White keeps the king on the kingside and plays for central and queenside pressure.
Bayonet Attack

Tactical Alerts
For White: Don't castle queenside without proper preparation. Black's attack can be devastating.
For Black: Time the ...f4 advance carefully. Premature attacks can backfire against precise defense.
