Putih menyekakmat dengan memojokkan raja hitam

Diagram pertama menunjukkan posisi sekakmat dasar dengan benteng, yang dapat terjadi di tiap tepi papan. Raja hitam dapat berada di kotak mana saja di tepi papan, raja putih bersiap melawan, dan benteng dapat menyekak dari kotak mana saja baik vertikal maupun horizontal (dengan asumsi bahwa tidak dapat dimakan). Diagram kedua menunjukkan posisi yang sedikit berbeda saat raja tidak berhadapan tetapi raja yang bertahan harus dipojokkan.
Dengan pihak berbenteng yang bergerak, sekakmat dapat dipaksakan sampai 16 gerakan dari berbagai posisi permulaan.
Dalam diagram ketiga, putih menyekakmat dengan membatasi raja hitam membentuk formasi persegi panjang dan mengecilkan formasi untuk memaksa raja ke tepi papan:
