alt Hacker NewsI agree that complexity can vary widely even with mate in 1. Lots of mate in 1 chess puzzles to prove that.
But in the case of this game, I wouldn’t say that they missed the mate in 1 due to the complexity of the position or the previous moves. They both just had the same blind spot, happens every so often.
Yeah but in this position Qh7# was literally the main idea in the position. It wasn't like some surprising idea. But I think it's logically explainable. When you're playing the game, each move you're considering what changed with your opponent's move, and after black plays h6 your mind naturally considers the pawn rather than the square. So it's easier to miss that h7 has become weaker.
If Magnus, or probably any player over ~2300, saw this position in a vacuum, they'd all literally instantly see Qh7#. It's basically impossible to miss, except for this weird nuance!
