Meninas
            Sejam bem-vindas ao nosso ESPORTE.
            Ah, vocês não fazem idéia do que estão perdendo...
         E ficarão encantadas com a beleza de certas partidas.
         Lindas partidas: de um Sidney Marra, de um Waldemar Bakumenko, de um Antonio Fabelo Chaves, de um Lourival Mendes França.

Frase célebre
            “O tempo em que o Jogo de Damas era considerado como um passatempo já acabou. É, na verdade, um desporto intelectual de primeira ordem, próprio para afastar a juventude dos fúteis e fáceis prazeres; o jogo começa com meios absolutamente iguais, o que exclui qualquer parcela de acaso!” (Pierre Lucot ─ ex-secretário-geral da Federação Mundial do Jogo de Damas). Paris─França.

Frase célebre
            “Para estimular a memória e aguçar a inteligência nada há de melhor que um bom problema de damas. E por esse motivo, recomenda aos alunos do curso secundário a resolver diariamente problemas do jogo de damas”. (Dr Richard Schmidt ─ professor e diretor, em 1932 da Dublim─School).
