Four Knights Game
The Four Knights Game is a symmetrical opening where both sides prioritize developing their knights to their most natural squares. Black usually has good chances of equalizing, which is why 3.Nc3 (the Three Knights Game) is considered unambitious for White.

Characteristics
- 🛡 PositionalSlower opening where plans, maneuvering, and structural advantages matter more than forcing tactics.
- 👥 PrevalentCommon enough that opponents are likely to have experience and prepared responses.
- ⏳ TheoreticalNeeds concrete preparation, but not necessarily the extreme depth of the heaviest theory openings.
- 🔀 TranspositionalOften reaches other openings through move-order changes, so lines overlap with nearby repertoires.
Strategic guide
Plans and motifs
- The central pawn breaks, d4 for White and ...d5 for Black, are more difficult to prepare since the c-pawns are both obstructed by knights.
- A common plan for both sides is to pin the opponent's queenside knight (i.e. Bb5 and ...Bb5), undermining the opponent's e-pawn.
- If Bxc6 or ...Bxc3, either side will gladly accept doubled c-pawns, as it becomes easier to prepare the central breaks d4 and ...d5.
