I would like to allow myself to disagree. I see atleast a third option to solve
a game like chess:

first:
real-time search
to reach a position with the properties defined by either
A1, A2, A3,...,A(n-1) or An

second:
real-time search
to reach a position with the properties defined by either
B1, ..., B(m-1) or Bm

third:
real-time search to win the position

assume you can proof that a position with the properties defined by either
A1, A2, A3,...,A(n-1) or An can be reached by (e.g) white within 20 moves

assume you can proof that each of those position (e.g.) white can transform into
a position with the properties defined by either
B1, ..., B(m-1) or Bm
within another 20 moves

assume you can proof that all these positions can be won within further 20 moves
(or atleast transformed into a TB ending that is won)

Wouldn't that be sufficient to call the game solved?
(Although I don't expect us to reach it)
