No, a king cannot "eat" another king in chess.
Chess Kings and Capture
While the term "eat" is commonly used, in chess, we use the term capture. According to the reference, a chess king can capture an opponent's piece if the piece is one square away in any direction.
Why Kings Cannot Capture Each Other
- Kings cannot move onto a square where they would be under attack (in "check").
- Because kings move only one square, two kings can never be next to each other.
- Therefore, a king can never "capture" another king. The game would be over (checkmate) long before that scenario could ever happen.
Conclusion
In the game of chess, kings cannot capture or "eat" each other as that would violate the rules of the game where a king can not put itself in check or capture a king.
