Açıklama
Üç hamlede mat, Beyazın Siyahın her savunmasına karşı en fazla üç kendi hamlesinde çözmesi gereken . Sınırın tamamını kullanan bir varyantta dizi Beyaz, Siyah, Beyaz, Siyah, ardından Beyaz mat eder.
İlk hamle, bütün yasal yanıtlara karşı hedefi güvenceye almalıdır. Aradaki ek beyaz hamlesi, son mattan önce taşların koordinasyonunu değiştirmek gibi sığmayan hazırlık manevralarına izin verir. Bu, kompozitörlere stratejik fikirler için daha fazla alan açar, ancak üç hamlede mat otomatik olarak daha zor değildir.
Yaygın notasyon #3'tür. Sınır dört veya daha fazla beyaz hamlesi olduğunda problem kategorisine girer.
Sık karıştırılanlar
Toplam üç tekil hareket
#3'teki üç, Beyazın hamlelerini sayar. Savunma tam uzunluğu kullanırsa aralarında iki siyah hamlesi de bulunur.
