Main lesson
Calculate forcing threats and defensive resources instead of judging a complicated attack by material alone.
Lesson notes
Moves 1–11 — central tension
- Both sides develop and prepare competing plans before the centre closes.
Moves 12–22 — activity over material
- ...e3 disrupts White's position while Black's knight and queen approach the king.
Moves 23–30 — the forcing storm
- ...Nxh4 opens the king, then ...Re6 and ...Rg6 bring the rook into play.
- White's queen sacrifice is a defensive attempt, not Black's attacking sacrifice.
Moves 31–39 — calculate to the end
- Both sides use checks and captures, but Black's queen survives with decisive threats.
What your student should learn
- Track material and king safety separately.
- Use a rook lift to reinforce an attack.
- Calculate defensive queen sacrifices as well as attacking ideas.
- Follow forcing variations without losing piece locations.
Rules to remember
- Rule 1Do not assume an attack wins because it looks dangerous.
- Rule 2Check every forcing defensive move.
- Rule 3Keep track of which side made each sacrifice.
Mini tournament checklist
- ✓ Can I list all checks for both sides?
- ✓ Which piece can join the attack next?
- ✓ What material am I actually sacrificing?
- ✓ Have I followed the line beyond the first capture?
Coach's challenge
Stop after 28.Qb7. Explain ...Rg6 and calculate what happens if White takes the rook on a8.
