How this board is solved

Solving this 13x13 board takes 17 deductions and needs the intermediate group-lock techniques, drawing on 6 distinct techniques. The first queen you can place for certain is K1. The queens resolve in the order K1 → G10 → F13 → J4 → H12 → E11 → D2 → C9 → L7 → I8 → B6 → A3 → M5. Every step follows by logic, so you never have to guess.
