If we take the definition from https://en.wikipedia.org/wiki/Solved_game: *'Provide an algorithm that secures a win for one player, or a draw for either, against any possible moves by the opponent, from the beginning of the game.'* then no, I did not mean that, and that's why I asked you if he actually wrote a program that does this for 7x7. Strong humans players including some pro's claimed to have solved 7x7 already back in 1989 (see my phd thesis for a reference), but AFAIK they did not implement an algorithm, so just like most of the other small board results by humans these were never really proofs in a strict sense. Best, Erik
