Thank you, guys.I don't at all understand all the ire directed at Checkmate, and not to start a debate, but what Checkmate does is very, very obvious. So, I hope this explains the difference between Stalemate and Checkmate, and why the position in question is NOT a stalemate. Making a move that puts your own King in check is illegal. Why? Because moving the Pawn will put the King in check by the Rook. The King cannot capture the Knight because the King can only capture a piece next to it.Capturing the attacking piece 'the Knight' with either your King or any other Piece. If there's a check by another piece, such as the Rook, we may be able to block the Check with another piece (to put a piece between the Rook and the King) This is not possible here because the Bishop is attacking the only free square. To understand what this means, let's review the 3 ways of getting out of check! The Knight is giving the King a check, and there's no way for the King to get out. So, in the screenshot, there is Checkmate. So, the game is called a draw by stalemate. Black has to move because it's their turn, but there's no legal move and it's not in check. Here's an example where the Blck King is NOT in check after White's last move 'Qc7'. A stalemate happens when one of the players' King is NOT in check, but the player has no legal move. It helped me a lot and I hope it will help you as well! 😃 Types of Checkmates Here's a very resourceful article with common types of checkmate. The White King is in check and there's no way to get out of check. Here's an example where we see the Black Rook giving a check to the White King. A checkmate happens to the player whose King is in check and there's no way to get out of check. So, first off, let's review what both Checkmate and Stalemate mean. Adding to that an absolute pin theme, I thought that it's best to have this question answered in a post to be a good resource for many new chess players in the future. I realized that many new players share the same confusion. When I was first introduced to chess, Stalemate was one of the most confusing rules to me. Today, I received this question 'I’m still confused about the difference between stalemate and checkmate.
