Key ideas for both sides

White

  • Answer ...Bb4 with e3, Bd3 and short castling, then trade on d5 to gain the center.
  • After ...Bb7 and ...d5, take with cxd5 and use Bb5+ to disturb Black's development.
  • Against an early ...d5, the knight jump Ne5 and Bf4 give White strong central squares.
  • Keep e4 as a long-term goal; the c3 knight already supports it.

Black

  • Pin the knight with 4...Bb4, castle, and follow with ...d5 and ...c5.
  • 4...Bb7 keeps control of e4 and can lead to a pawn on d5 after ...d5.
  • Strike with ...c5 once castled to open the c-file and hit d4.
  • Avoid an early ...d5 without ...Bb7 support, since Ne5 and Bf4 give White easy play.

Plans and pawn structure

If Black pins with ...Bb4, the game looks like a Nimzo-Indian: Black may trade on c3 to double White's pawns, and White builds with e3, Bd3 and castling. After ...Bb7 and ...d5, the center becomes symmetrical after cxd5 exd5, and White uses Bb5+ and Bd3 to keep pieces active. Black's main break is ...c5, while White looks for e4 in the long run.

Where it goes next

How to play against it

As Black, choose 4...Bb4 or 4...Bb7, both solid. Do not rush ...d5 before your pieces are out, because Ne5 and Bf4 grab good squares. If you pin, be ready to trade on c3 when doubled pawns would weaken White's queenside structure.
