Chess: 900 to 1800

Orthodox Defence: 4.Bg5 Nbd7

White pins your f6-knight with 4.Bg5. You answer 4…Nbd7, which sets the Elephant Trap (see Traps) and, after …Be7 and …O-O, reaches the classical Orthodox Defence. The plan to remember: castle, play …c6, take on c4 only after White's bishop has gone to d3, then …Nd5 trades two pairs of minor pieces and …e5 (or …c5) frees the c8-bishop.

Seven lines, three of them core:

  • Capablanca’s freeing manoeuvre (7.Rc1) (core)
  • Capablanca line: 13.dxe5 (core)
  • Capablanca line: 13.Bb3 and the isolated pawn (deeper)
  • Capablanca line: 11.Ne4 avoids the trade (deeper)
  • 7.Qc2: same manoeuvre, different finish (core)
  • 7.Bd3: take at once and break with …c5 (important)
  • 5.Nf3: the same position by another road (deeper)

Learn takes up to five new lines at a time, core lines first. When the chapter is learned, practise it from memory.
