Forced Checkmates That Might Just Break Your Brain (Part 1)

the mate in 16 with the knight was ridiculous! I realised you had to underpromote to a knight, but i had to use stockfish to find h3!

Please not that, in your variation (mentioned in the paranthesis) after 6.Ba5 — Black is not forced to play a2.
Black could instead play Ka2 which would prolong the task even more.
I hope you get the point & thank you for the query.

For someone who is used to chess problems the 2nd Mate in 16 is rather trivial.

  1. The key is given by restricting black.
  2. Only piece that can mate is a knight
  3. As black can only move his Queen you can simply count the moves and see where the Queen is after capturing the pawns and going Na5.
  4. A knight can't loose a tempo hence the solution is clear
