Four Knights Game: Spanish Variation — Chess Library

Both sides develop both knights before committing the center. Bb5 adds Spanish pressure while keeping the position sound and easy to navigate.

Lesson

White to move. Main line: 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. Bb5 Bb4 5. O-O O-O 6. d3 d6 7. Bg5 Bxc3

The opening’s name describes its first strategic fact: all four knights reach natural squares, so neither player can win time by attacking an undeveloped piece. White’s Bb5 increases pressure on c6 and indirectly on e5; Black mirrors with ...Bb4.

Both kings castle before the center opens. White’s d3 supports e4 and frees the c1-bishop, while ...d6 gives Black the same stability. After Bg5, ...Bxc3 exchanges a bishop for the c3-knight and asks White how to handle the resulting pawn structure.

This is a useful opening for learning development without autopilot. The pieces come out naturally, but the bishop exchange, central break and choice between a quiet or open game still require a plan. Count structural concessions as carefully as tempi.
