  • Pattern
  • King

Major piece is a mating concept: a queen or rook, also known as a heavy piece. The primary distinction of major pieces versus minor pieces is that major pieces are capable of checkmate with only their own king for support, as the enemy king is unable to step across the ranks and files they control. The teaching point is to identify which escape squares are controlled and which defender is missing.
