Explicação
Um moremover é um cujo limite é de quatro lances das brancas ou mais. As pretas continuam resistindo, e as brancas devem demonstrar que o mate pode ser forçado contra todas as defesas legais dentro do número indicado.
Na notação usual #n, n representa o número de lances das brancas. O limite é puramente de extensão: #4, #5 e qualquer mate direto com mais lances entram nessa categoria. Um ainda pertence à sua própria categoria, assim como um .
A maior extensão permite construir planos com mais preparação, desvios e manobras antes do mate, mas não muda o objetivo fundamental. Moremover não significa simplesmente problema longo: um mate ajudado ou um mate inverso de quatro lances pertence a outra classe porque muda a relação entre os lados.
Confusões frequentes
Qualquer problema de quatro lances
Moremover designa especificamente um mate direto de quatro ou mais lances das brancas. Outros tipos de composição podem ter a mesma extensão sem serem moremovers.
