Comments.Text: @IanBush OP posted the FEN `5Kbk/6pp/6P1/8/7R/8/8/8 w - - 0 1` which is White to move. I find it very unlikely that an engine missed this mate in 2.  Lichess' web-based Stockfish finds it immediately running on 12 year old hardware.

Comments.Text: @SecretAgentMan That's why I am asking. I also can't believe any engine from the last 10 years or more missed this.

Title: Mate in 2 from "The soviet Chess Primer" but wrong
ThreadText: # Mate in 2 from "The soviet Chess Primer" but wrong
  
  (Asked by: username_0 on 2023-12-09)
  
  I found this exercise on page 51 of the "The soviet chess primer" and I think there is a mistake. Chess.com analysis says there is a mate in 13 moves.
  
  I'm correct thinking there is a mistake? Or am I missing something?
  
  ```
  5Kbk/6pp/6P1/8/7R/8/8/8 w - - 0 1
  
  ```
  
  Edit: here the solution that the engine didn't find:
  
  ```
  1. Rh6 gxh6 2. g7#

  Checking a chess analysis board myself, there is a mate in thirteen with black to move. It is very likely that this is what you set up on chess.com.
  
  The puzzle was certainly intended with white to move. Try again to find the mate in two with white moving first, yourself. And, if you do want to use the computer again, make sure you set it up correctly with which side has the move.
