Stalemate/Checkmate Combo - Puzzle 2: Checkmate
(Published on 15. July 2020, 21:04 by HalfBakedLunatic)
Rules:
Puzzle number 2 has the same rules as number 1 – except that the King in Box 5 is in “Checkmate” ... that is, that one King is “in Check” by one – and only one – Bishop or Knight, and it would still be in Check if it moved to any of the 8 surrounding cells (obviously, this one king - being in check - will violate one of the last two rules).
* Normal Sudoku rules apply
* Kings are 1, Bishops are 2, Knights are 3
* No two Kings can be a “Kings Move” apart
* No King can be a “Knight’s Move” from any Knight
* No King can be on the same diagonal as a Bishop, unless a Knight is blocking the path
Puzzle 2 - Checkmate
NOTE: If you use the online tool, turn on the "Panel" and hit the arrow to enter Chess pieces - or just use numbers 1, 2, and 3.
This is my very first time creating a Sudoku puzzle, I hope you enjoy it. I've also posted a video on YouTube showing a bit of the process I went through creating these two puzzles: https://youtu.be/4fsXdxG38yc

Thank you Bob, yes - that's exactly why I wanted to try creating these. I'm glad you enjoyed them!

I enjoyed this pair of puzzles. The rules work well together and seem more authentically "chess-y" than some of the other variants on the portal, especially with the emphasis on protecting the king, knights blocking bishops, etc.

I don't think this puzzle is easier than the first one (although the sudoku part might be a bit easier) since the fact that the center box king can be in check prevents a lot of eliminations early on, as was the case with stalemate.

Once I understood the thought process, I found this one easier than the first! Very Very nice puzzle!

@Zorant that is exactly right in this puzzle. In the ‘stalemate’-version, not even the king in the central box may be under attack, but in this one it has to be exactly once

Hi Zorant - sorry if it wasn't clear. The two puzzles are meant to go together, so in puzzle one, the King in the central box (Box 5) is in "stalemate" and in this puzzle the King in the central box (Box 5) is in "checkmate" - but just that one king, none of the others.

This took me well over an hour - and yes, I did need to watch your video to get through a couple of the more difficult parts, I hope that's not cheating!

Ok. This means that only one king can be attacked from one figure. He cannot be attacked by a knight and a hunter at the same time?
Other kings must not be attacked?

@zorant Actually, the king in the central box is the only king that may be in check(mate). I guess the fourth and fifth part of the ruleset should repeat that one exception will be made for the king in the central box.

Hi,
The rules are not clear to me until the end. Whether a king in the central box or any king in the grid must be attacked with a checkmate move.

Added a "Sudoku" label
