Observação ─ Diagramas 1 a 4: jogam as brancas e EMPATAM

1 

                                              1. h8-a1                       h6-c1

         Se 1. ... h6-f8?   2. h4-g5 e, coroando mais duas pedras, as brancas vencem pela Forçada.

                                               2. a1-h8                       c1-h6

                                               3. h8-a1                       h6-c1

e, como a mesma posição se repetiu 3 vezes, quem estiver com a Dama solitária já pode exigir o empate*. 

2

        Observação ─ Confronte este final com o de nº 22. (Esse  final ainda vai ser publicado em DAMAS para crianças e adolescentes ─ 15, ou seja, a próxima postagem). 

                                               1. b8-h2                       a7-g1!

         Se 1. ... a7-c5/d4/e3/f2   2. h2-g1   3. a5-b6, etc, e ganham as brancas pela Forçada.

                                               2. h2-f4                        ...

         Quando 2. h2-b8, o correto é 2. ... g1-a7!

                                               2. ...                              g1-f2

         Se 2. ... g1-h2?   3. f4-e3, etc, com a vitória das brancas.

                                               3. f4-e5                        f2-e3

        Se 3. ... f2-g1?   4. e5-h2 e 5. h2-g1 e foi-se a esperança de empate.

                                               4. e5-c3                       e3-f2

                                               5. c3-e5                       f2-e3

com empate. 

3 

                                               1. f8-h6                        c1-a3

                                               2. h8-d4                       ... 

       A Dama preta não deve sair da tridiagonal a3─f8─h6─c1, e, mesmo assim, é obrigada a se movimentar da casa a3 para f8 e vice-versa.

      O grande retângulo (a5─d8─h4─e1) está, neste momento, proibido, como neste exemplo: 2. ...a3-b4? 3. h6-d2 b4xe1  4. d4-f2 e1xg3  5. h2xf4  e as brancas vencem. 

                                               2. ...                              a3-f8!

                                               3. d4-g1                       f8-a3!

                                               4. h6-c1                       a3-f8!

                                               5. c1-h6

com empate. 

4

                                               1. f8-h6                        c1-a3

                                               2. h8-e5                       a3-f8

         Se 2. ... a3-b4?   3. e5-g3 h2xf4   4. h6xa5 X.

                                               3. h6-c1                       f8-a3

         Se 3. ... f8-e7?   4. e5-g3 h2xf4   5. c1xd8 X.

                                               4. c1-h6                       a3-f8

com empate.
