DAMAS para crianças e adolescentes ─ 12

5. Combinações (continua)

Anexo ─ Notação do tabuleiro 

NOTA

1. Antes de você começar a estudar este item 5 ─ Combinações, gostaria de lembrar que, na postagem anterior deste blog (DAMAS para crianças e adolescentes ─ 11), de 13.05.12, foram publicadas, aqui, as Regras Oficiais do Jogo de Damas ─ válidas para todo o território brasileiro.

2. Aproveito o ensejo e repito, agora, a Notação do tabuleiro, já do seu conhecimento, certamente, devido à sua publicação em postagem anterior.

3. Se você tem alguma dúvida acerca das Regras de Damas, ou se não decorou, ainda, a Notação do tabuleiro, é chegada a hora da releitura de tudo isso, e solicito a você que o faça agora e já, pois essas Combinações...  

ANEXO

Notação do tabuleiro

 

        Observe, antes de tudo, que o tabuleiro se divide em:

       a) colunas (linhas verticais), de a até h;

       b) travessas (linhas horizontais), de 1 até 8.

       A Notação do tabuleiro é, pois, alfanumérica, isto é, cada casa é assinalada pela combinação de uma letra com um algarismo.

       Exemplo 1º – A coluna c combinada com a travessa 3 registra-se assim: c3.

       Exemplo 2º – A coluna f combinada com a travessa 8 registra-se assim: f8.
