checkmate versus stalemate

Ask google

For checkmate the king has no legal moves and is attacked. 

For stalemate the king plus all other pieces have no legal moves, but the king is not attacked. 

What do you mean by that? Maybe you could post an example?

+1 Or as FIDE has it...

Artical 1.2

The objective of each player is to place the opponent’s king ‘under attack’ in such a way that the opponent has no legal move. The player who achieves this goal is said to have ‘checkmated’ the opponent’s king and to have won the game. Leaving one’s own king under attack, exposing one’s own king to attack and also ’capturing’ the opponent’s king are not allowed. The opponent whose king has been checkmated has lost the game.

Artical 5.1a.

The game is won by the player who has checkmated his opponent’s king. This immediately ends the game, provided that the move producing the checkmate position was a legal move

Artical 5.2a.

The game is drawn when the player to move has no legal move and his king is not in check. The game is said to end in ‘stalemate’. This immediately ends the game, provided that the move producing the stalemate position was legal.

For a checkmate you have to check the king ( a piece of yours must "see it") for stalemate, you have to move the king (you don't have other pieces that can move) and the king can't move but isn't in check

Hi! My name is Lauren Goodkind and I'm a chess coach based in California.  Checkmate is when the king is in check and cannot escape check on the very next move. If you checkmate somebody, then you win!  

Stalemate is when the king is not in check, and has no legal moves.  Stalemate is a draw, or a tie.   That means nobody wins and nobody looses.  If you have many queens on the board and your opponent just has a king, it's easy to accidentally stalemate your opponent.  

  I hope that this helps.  

Almost, just to clarify...

Stalemate is when the player to move has no legal move and his king is not in check. That's no legal  move with any of their pieces not just the King.

Пат это правило придуманное конечными людьми))))))) у вражеского короля НЕТ ХОДА , ПОЧЕМУ НИЧЬЯ?????? ахаха это раздражает)

In mainline chess tradition, the game is won when the king enters checkmate, but in some African traditions, the game is won when the king is captured. Going that one step further makes it easy to tell the difference between checkmate vs. stalemate. 

It is against the rule for the king to move in a place where it is attacked. This is a stalemate because there is no way for black to capture the king and no way for white to move without being attacked. 

This is a checkmate, because the white king can not move anywhere and avoid being captured.  And once the king is captured, the game is over. 

ok

That's a good analogy. You could have illustrated the stalemate diagram better had you given both sides some pieces. As above, stalemate is not simply when a player has no legal move for the king but when they have no legal move for any of their pieces. For example, White to move...
