Yes, you are correct, you are right, you are consistent, you are sympathetic!
But you don't understand the chess truth that you can't be _winning_, if you
don't play! BTW the text of an older rock song. Excuse me that I must insist.
But as you know I even contradicted Marilyn vos Savant! I did NOT say that he
was winning. Because he stopped playing. But what I say is:

ROLF: If Kasparov had played on he would have won Game 2 and drawn Game 3!ROLF

That's right! And sure nobody can't find a forced winning IF he stops continuing
to play! Because then he only draws or loses. Both options were already chosen
by Kasparov in the past.
