Four Knights Game
Also known as Double Ruy Lopez (Symmetrical Variation)
1.e4 e5 2.Nf3 Nc6 3.Nc3 Nf6
The Four Knights is chess at its most honest: both armies march their knights to the natural squares and stare each other down across a balanced centre. It is a calm, classical battlefield where understanding outweighs memorised tricks - ideal for learning how to fight for the centre, develop sensibly and castle early.

What it does
Both sides develop all four knights before committing the bishops, giving a symmetrical Open Game. The central tension is the classic e4 versus e5 stand-off: each pawn is defended and attacked twice, so neither falls easily. White's most testing try is the Spanish Bb5, pressuring the c6-knight to chip at e5's defence. Play continues with quick castling and modest pawn moves, after which White uses Bg5 to pin the f6-knight and keep a small initiative.
When to use it
Reach for the Four Knights when you want a sound, low-theory 1.e4 e5 game that rewards good principles over sharp memorisation. It suits beginners building healthy development habits and improvers who prefer to outplay opponents in the middlegame. It is a calm alternative to the heavy theory of the Ruy Lopez or the wild Italian gambits, and a fine practical answer to symmetry-loving opponents.
Why it works
Its strength is soundness: every move follows a sensible rule - knights before bishops, fight for the centre, castle early - so White rarely ends up worse while keeping a tiny edge with the move. The Spanish Bb5 is respected because it puts real, lasting pressure on e5 without risk. Because the structure stays solid and flexible, White can choose quiet manoeuvring or timely breaks (d4 or f4) once Black commits.
Key ideas
- Develop all knights first, then bishops, then castle quickly.
- Use Bb5 to pressure c6 and undermine the defence of e5.
- Pin the f6-knight with Bg5 to pile pressure on e5.
- Prepare central breaks with d4 or f4 once Black commits.
- Keep it solid - a small, lasting edge beats a rushed attack.
- Win the e5/e4 battle and you control the game.
Watch out
Beware the Halloween Gambit (4.Nxe5?!), which sacrifices a knight after 4...Nxe5 5.d4 to chase Black's pieces back with pawns. It looks scary but is unsound - if Black returns the piece sensibly and develops calmly (for example ...Ng6 and ...d6), the extra material wins. Don't panic and don't grab greedily.
