Spiegazione
Un'inchiodatura assoluta si ha quando un pezzo è tra un attaccante lineare e il proprio re. Abbandonare la linea lasciando il re attaccato è illegale.
Per esempio, una torre può inchiodare un cavallo al re sulla stessa colonna; se ogni salto scopre lo scacco, il cavallo non può rompere la .
Assoluta non significa sempre immobile: torre, alfiere o donna possono muoversi lungo la stessa linea, catturare l'attaccante o interporre una difesa mantenendo il re sicuro.
L'inchiodatura termina muovendo il re, catturando l'attaccante, bloccando la linea o cambiandone la geometria.
Nella il pezzo può spostarsi perché dietro non c'è il re.
Confusioni comuni
Assoluta e immobilità totale
Sono vietate solo le mosse che espongono il re.
Inchiodatura assoluta e relativa
L'assoluta limita la legalità; la relativa consente di muovere con un costo possibile.
