Thorsten, these discussions are often fun, but _please_ don't make statements
that are utter nonsense.  An example:  take position fine 70.  I take white.
I play Kb1.  I win no matter what you do.  _that_ is accurate.  I will be
happy to construct as many positions as you care to try, where there is a
correct move to win, even though I don't feel like calculating to the ultimate
mate.

I am also willing to construct positions where there is more than one winning
move, so long as you recognize the winning _idea_.  That is _also_ accuracy.

So drop this "drive into the fog" nonsense.  It only gets you involved in a
massive wreck.

see above.  this is simply incorrect.

I can think of several ways this can be done.  Not legally, perhaps, but
_still_ done.  :)

Correction (important correction).  Not "accurate".  "accurate as possible".
There is a huge difference in the two terms.

Care to take my position test?  I'll make 10 positions, you either find the
right move or you lose/draw.  Humans do this _all_ the time.

If you don't want accuracy, _how_ can you know where the moves lead?  That
is a 100% circular argument.  If it leads to a position you know you can win,
then yes, I like that move.  If it leads to a position where I am material down,
and I can't see winning or losing, then _no_ I don't like that move.

Not me. Haven't been inside a McDonald's in 25 years or longer.  No future
plans to visit one either.
