Just so you know. By using the definition you linked no games where the second player wins by force (like tik tak toe on a infinite bord) would count as solved.
Can you elucidate, please?
A game under FIDE basic rules prior to 2017, but with the diagram in art. 2.3 (the starting position) replaced by
would seem to be a game where the second player wins by force. The strategy, "make the top move from the Syzygy site" would seem to count as a weak solution securing a win for Black according to the definition in https://en.wikipedia.org/wiki/Solved_game , which I think is the link you're referring to.
How not?
I am familiar with ultra-weak solutions that use the strategy-stealing trick. For hex, this gives the value of the initial position but it does not give the value of most other positions. So this is NOT your number 2 (which is what I corrected).
