If your program can find not only Nxh6 but also winning moves after Nxh6 c3 and in more positions after Nxh6 when programs have problem to find the winning move then I consider the position as solved. Based on the pv of your experimental Junior I doubt if Junior can solve it fast based on my definition. The main question is how much time does Junior need to find a winning move after Nxh6 c3. Uri
