n...Qxb2 is not a threat when

• bishop is defending it on c1
• bishop is preparing queen trap on d2: n+1...Qxa1 n+2. Bc3

• Protected queen in front of the king will push the king backward.
• Ladder mate with two rooks can be captured by the enemy king.
  • Keep the pieces as far away from the enemy king as possible.
• King and bishop or knight cannot deliver a checkmate. King and two knight also means draw. But king and a pawn can win.

• Push the enemy king to the edge as the ladder mate.
• Knight opposition by queen.
• Queen boxes the enemy king.
• Push until only two squares are left for the enemy king, walk the king to the corner + (2,2) and deliver checkmate with the queen.

• Rook cannot trap the opposing king.
• Get help from king to push the king to the corner.
• Rook keeps the opposing king from escaping and knight opposition by king. If the opposing king directly opposes the king, use rook to force the opposing king to back up.
• If the rook gets attacked then move the rook to the other end.
