Variation 1: The Main Line

Typical continuation:

d4 d5 c4 e6 Nc3 Nf6 Nf3 c6 Bg5 h6 Bh4

Key ideas for White:

• Control the center with pawns and pieces

• Look for tactical opportunities

• Surprise value against unprepared opponents

Strategic Plans and Key Ideas

For White:

1. Central control: Maintain pawns in the center when possible. The center is the most important part of the board!
2. Piece development: Get all pieces into the game quickly. Don't move the same piece twice in the opening.
3. King safety: Castle early, usually kingside. A safe king allows you to attack more freely.
4. Create threats: Look for tactical opportunities. Don't just develop aimlessly.
5. Space advantage: Use extra space to restrict Black's pieces and create winning plans.

For Black:

1. Counterplay: Look for ways to create threats against White's position
2. Piece activity: Ensure all pieces are actively placed, not just developed
3. Pawn breaks: Know when to strike with key pawn moves like ...c5, ...e5, or ...f5
4. King safety: Don't neglect castling and king protection
5. Patient play: Sometimes you need to wait for the right moment to strike

Common Mistakes to Avoid

Mistake 1: Neglecting development

Problem: Moving pawns too much or moving the same piece multiple times in the opening.

Example: After d4 d5 c4 e6, don't waste time with unnecessary pawn moves.

Solution: Follow the principle of developing a new piece with each move in the opening. Get your knights and bishops out first!

Mistake 2: Castling into danger

Problem: Castling on the side where the opponent has attacking chances.

Solution: Assess pawn structures and piece placement before committing your king. Sometimes it's better to castle queenside, or even delay castling!

Mistake 3: Ignoring the center

Problem: Focusing on wing play while neglecting central control.

Solution: Always keep an eye on the center - it's the most important part of the board. Control the center, and you control the game!

Mistake 4: Playing too fast

Problem: Making moves without considering your opponent's threats.

Solution: Always ask yourself: "What is my opponent threatening?" Take your time and think!

Mistake 5: Allowing White's key plans

Problem: Letting your opponent execute their ideal setup without any resistance.

Solution: Challenge your opponent's plans early. Create threats and don't be passive!
