Very strange. A few weeks ago there were Guus's problen 7# on
this forum. Solution was 1.Bg8 Ne6 2.Bh7+ Ng8 3.Bg8 Ne6 4. Qf1!,
reasoning that Black can no more castle, otherwise Black could
have claimed for draw instead of 3. - Ne6. But think that Black
just made that move. Now White has option to claim a draw, but
he is trying to win. So he tries 4.Qf1, but then surprisingly
4. - 000. I have not read the article 18 in de Codex. I have
read articles 1-2 which tell that problem chess rules are due to
the on the board chess conventions unless for some special
reason otherwise stated. And I see no reason why article 18
should make any exception. I must read that article. Olli.
