Go for the big win
Lord chaos after 16. Kd3 why not 16. Qb3+ then theirs would be 17. Kd2 (forced) then 17. NGf3#?
I think you mean Ke2 (forced) and Nef3+. Black has Kd2 in response to your "NGf3#".
@Streptomicin. Yes that works, there are lots of ways. "or Ne5+ or Rd8"
Yeah, Lord-Chaos, I think you're having a meltdown... 17. c5 Ne5#, definitely checkmate, I have no doubts.
