I would probably give the credit to Harry Nelson.  He suggested this in 1978
because of his fetish for solving chess problems, and this tends to push the
'almost solution' to the top part of the move list.  I've used it ever since...
I didn't hear of it prior to that, but I have told many about it since that
time.
