← Queen's Indian Defense

Practice: Miles Variation (4.Bg5)

Pin before fianchetto

White pins the knight on f6 before committing to a fianchetto. This system leads to positions similar to the Rubinstein Nimzo-Indian but with Black's bishop on b7.

1. d4 Nf6
2. c4 e6
3. Nf3 b6

Key strategic ideas

  • Black places the light-squared bishop on b7, controlling e4 from a distance instead of occupying the centre with pawns.
  • White often plays b3 and Bb2 to mirror Black's setup. The game becomes a quiet strategic battle where small advantages matter.
  • The ...Ba6 line is a sharp attempt to trade light-squared bishops. This reduces White's attacking potential and makes Black's position easier to play.

Common mistakes & traps

  • After 4.a3 Ba6 5.Qc2 Bb7 6.Nc3 c5 7.e4, Black must not play passively. If Black tries 7...Nxe4? 8.Nxe4 d5, White can defend with the queen on c2 and come out ahead.
  • The Fianchetto Variation (4.g3) seems quiet, but Black who plays ...d5 carelessly can end up in a bad position. The Bg2 puts lasting pressure on the queenside.

Pawn structure notes

The structure is flexible with Black's pawns on d5 and e6. White's centre (d4-c4) faces pressure from the b7 bishop. The tension in the centre can last well into the middlegame.

Tips

  • 4.Bg5 pins the Nf6 and prevents Black from playing ...d5 without unpinning first
  • White develops normally with Nbd2 and e3, avoiding committing the queen's bishop
  • A solid positional approach that keeps the centre flexible
