Probably out of reach for solving rigorously. A strong engine equipped with something like the opening books at https://katagobooks.org/ might well “solve” the game in the sense of always winning won positions and at least drawing drawn positions (if the komi value used makes draws possible). I suspect that always getting the best possible score (but without rigorous proof that that’s so) might be in reach.
People reading this may be interested that 5x5 Go is solved. 7x7 Go is probably out of reach.
