NOTA
FINAL DIABÓLICO
         Como é sabido por quem nos acompanha desde o início desta seção do blog, há outro final, com igual quantidade de peças, mas com diferente distribuição dessas peças no tabuleiro: é o “Final diabólico”, como se transcreve adiante ─ Final 8 ─ de autoria do doutor Bolívar Mascarenhas. Ver postagens 36, 37 e 38.
