Main lesson

Children think "if I win a queen I must be winning". Morphy teaches the opposite: if all your pieces are attacking and your opponent's king is exposed, activity can be worth more than a queen.

Lesson notes

Moves 1–5 — everybody develops

  • Both sides develop quickly, nobody grabs material, nobody attacks yet.
  • Ask: who has developed more pieces? Answer: they are equal, so nobody should attack yet.
  • Tournament lesson — before attacking ask: are all my pieces playing?

Moves 6–10 — a pawn for activity

  • White wins a pawn. Morphy does not panic; he develops with tempo instead.
  • The rook becomes active, the bishop becomes active, the centre opens.
  • Ask: who has more active pieces? Material says White, activity says Black.
  • Defensive lesson — don't count pieces, count active pieces.

Moves 11–16 — perfect preparation

  • Morphy is not threatening mate; he quietly places every piece perfectly.
  • Queen, both rooks and the bishop all aim toward White's king.
  • Ask: which black piece is not helping? Answer: none — every piece has a job.
  • Tournament lesson — before attacking, bring every piece into the game.

Critical position after 17.Qa6 — stop here

  • Do not show Black's move yet. White attacks on the queenside.
  • Ask: should Black (A) defend, (B) move the queen, or (C) attack the king?
  • Most children answer A. Morphy chooses C: 17...Qxf3!!
  • Why can Black give the queen away? Because White's king becomes exposed while Black has two bishops, two rooks, an active knight and the open g-file.

Moves 18–20 — every move is a threat

  • Black never tries to win the queen back.
  • Every move is a check, a threat, or brings another attacker.
  • Ask: how many black pieces attack the king now? Almost every one.
  • Tournament lesson — when attacking, every move should create another threat.

Moves 20–24 — the bishops chase the king

  • The bishops give check after check while the rooks wait patiently.
  • Ask: why doesn't Black hurry? The attack is already winning — no need to force it.
  • Tournament lesson — don't rush winning positions, keep improving them.

Moves 24–28 — the quiet finish

  • 24...Bxf2 25.Qf1 Bxf1 26.Rxf1 Re2 27.Ra1 Rh6 28.d4 Be3 and White resigns.
  • The last move is not a check and not a capture — just a quiet move that makes every mate threat work.
  • That quiet finish is one reason the game is so admired.

What your student should learn

  • Count active pieces, not just points of material.
  • Rooks belong on open files pointing at the king.
  • A queen sacrifice is fine when the follow-up is forced.
  • Two bishops on open diagonals are a mating net.

Rules to remember

  1. Rule 1Active pieces are often worth more than material.
  2. Rule 2Don't grab pawns — finish development first.
  3. Rule 3Before sacrificing ask: will ALL my pieces join the attack? If not, don't sacrifice.
  4. Rule 4When defending, don't only count material — ask how many enemy pieces attack my king.
  5. Rule 5A queen sacrifice is not magic. It works only because Morphy prepared it: doubled rooks, active bishops, an advanced queen and open lines to the king.

Mini tournament checklist

  • ✓ Which of my pieces is doing nothing?
  • ✓ Are my rooks on open files?
  • ✓ Is the enemy king short of defenders?
  • ✓ Can I calculate the sacrifice to the end?

Run through this list before you start an attack in a real game. Mostly yes means look for tactics; otherwise improve one more piece first.

Coach's challenge

Cover Black's move after 17.Qa6 and ask: "Would you dare give away your queen?" Almost every child says no. Then reveal 17...Qxf3!! and ask why it works. The answer is not "Morphy was a genius" — it is that every black piece is already active while White's king has too few defenders.

Note: Morphy played Black here — practise as Black to find the queen sacrifice yourself. He spent about twelve minutes calculating 17...Qxf3!!
