Solving NoGo on small board sizes
3x3 is a first player win.
All three possible starting moves win.
4x4 is a second player win.
All three possible starting moves lose.
The program (BobNoGo) thinks that 1. B1 is the strongest opening, but
D3 is a winning reply. I did not check other replies.
Against 1. A1, D4 wins for White.
Against 1. B2, again the symmetrical move C3 wins for White.
Not proven yet.
The program likes to play in the corners first, as on larger boards.
I proved that the "four corner opening" 1. A1 2. A5 3. E1 4. E5 is a win for Black
with an alphabeta search.
