Critical Tactical Themes
Bishop Exchange
Black's main plan - exchanging the light-squared bishops to eliminate White's attacking potential.
Central Knight Outpost
White tries to maintain the central knight while Black puts pressure on it from multiple directions.
Defensive Coordination
Black's pieces work together to defend key squares and prevent White from creating threats.
Critical Points
For White: Don't allow all the pieces to be traded off. Maintain some attacking potential and avoid rushing into unfavorable exchanges.
For Black: Be patient and don't create unnecessary weaknesses. The solid structure is your main asset - preserve it at all costs.
