Four Knights Game
The Four Knights Game is a king-pawn opening in which both sides develop their knights toward the center early. Both sides develop their knights toward the center before committing the bishops. White can choose a Spanish-style bishop move or open the center with d4. Symmetry does not remove tactical threats or make quiet moves interchangeable.
Opening moves: 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6
White’s plan
Develop a bishop, secure your king and choose when to play d4. Check exchanges on e4 before assuming the knight on c3 defends everything.
Black’s plan
Complete development and seek a central break. Meet White's bishop placement and d4 plans concretely instead of copying every move.
Ideas behind the moves
e4
Put the pawn on e4 to occupy a central square. Compare the resulting center with the other branches.
Nf3
Develop the knight from g1 to f3. Connect this piece placement with the central structure.
Nc3
Develop the knight from b1 to c3. Connect this piece placement with the central structure.
Three mistakes to watch for
- Copying the opponent's moves after the position has become asymmetric.
- Assuming natural development makes e4 tactically safe in every line.
- Trading central pieces without considering development and the resulting pawn structure.

A tactical example
Mating net after 8...Kh8
After 8...Kh8, White has a forced mate in 3. Start from this real-game position and calculate the finish. The earlier game moves are context, not a recommended repertoire.
This trap depends on a specific opponent mistake. It is not a guaranteed win from the opening.
