Main lesson

Sacrifices work when your pieces are active and the opponent’s are not.

What your student should learn

  • Material is only worth what it does.
  • The King's Gambit trades a pawn for open lines.
  • Undeveloped pieces cannot defend their king.
  • Mate can be delivered by minor pieces alone.

Mini tournament checklist

  • How many of my pieces are active versus theirs?
  • Is their queen doing anything useful?
  • Do my sacrifices come with checks or threats?
  • Have I checked the mate to the very last move?

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.

Note: Count the pieces White gives away, then count how many black pieces defend. That comparison is the whole lesson.
