Young girl playing chess online on a computer while learning Legal’s Mate, a classic queen sacrifice checkmate tactic.

Think about the shocked face of your adversary once you have made your queen totally undefended. He picks up the best chess pawn and feels that he has won the game even before it starts. But within two moves, he finds himself being checkmated. This is no fantasy but a real chess tactic called the Legal’s mate.

If you are a beginner chess player and want to avoid falling into legal traps while playing online chess, then becoming familiar with the strategy behind this tactic is essential.

FAQs

  • An 8-move checkmate sequence where White sacrifices a queen to deliver mate using two knights and a bishop.
  • It should be written as 'Legal's Mate,' with both capital letters because it got its name after the great French player of the eighteenth century, Kermur Sire de Légal.
  • Scholar's Mate (4 moves) targets f7 with the queen and bishop directly. Legal’s Mate (8 moves) involves a knight sacrifice to draw the king into a mating net.
  • While most common under 1200 ELO, the tactical patterns of the Legal Trap are essential for all levels to recognize pins that aren't actually pins.
