Why did I get a stalemate when my last move put their king in checkmate?

If you play 43. Rg5+ , Kf6 is forced and then all you'd have to do is play 44. Qf4# ....

The ruling of a draw for stalemates is just a way to encourage players to be precise. It may take so much effort just to learn a small bit of extra endgame technique, but it definitely is a rewarding process. The rules for stalemate are finally changed to the current state, having been ruled as wins, losses and draws at different points of time in the past (of course, I was not old enough to have experienced the outcomes of wins and losses for stalemates).

Of course though, real life situations are different (you will not get rewarded, other than staying alive, for dodging continuous enemy attacks).  By the way, in other games such as chinese chess, stalemate is a win for the stalemating player. Not sure about other games.

No, if the King cannot move and they are IN CHECK, then they lose. If they cannot move but they are not attacked, it's a draw. I don't see what is flawed about that/

Then why do you have an account here if you hate the game?

I think what he is saying is that, they aren't going to change the rule, no matter how dumb it seems. There is no point in complaining beyond gaining an understanding and moving on. If you can't handle that, you should probably leave the site and or quit playing. Others are simply saying, it is a rule and you should learn to adjust to it. I am telling you, once you learn how to play and realize you can make a mistake and play for a draw, you will like it when the shoe is on the other foot. 

I sure like the way you answer questions and make your responses. You are one of the few people who always has something positive, encouraging, or valuable to say.

You're complaining for no reason just because you can? That's just like saying "I'm robbing a bank because why not?" or "I'm gunning down hundreds of students in a school because why not?" These excuses are indefensible and beyond useless. Pointless complaints like this ultimately cost you your health due to the unnecessary negative stress. Just accept that you have to adjust to the rules of chess. Otherwise, I suggest you go to your profile and click "Delete Account." Either way, I don't give a damn on what you think you are entitled to!

Calling chess crap is "contributing" to chess.com? I, Chesseract557, fervently disagree. You're not contributing to the site, you're dragging the site down.

And all this is all because someone mistook stalemate for winning the game or confused chess with Chinese Chess? That is beyond flawed. And you literally joined here one day ago, so what do you know about Chess? It is undoubtedly evident that you simply can't handle Chess. What exactly makes you think of Chess as crap, anyway? There absolutely must be a specific reason for this folly.

Or you're an outright troll due to your thread.

Ooh! Another thing that indisputably debunks your fallacious argument!

Chesseract, you're 100% right but you may not be very accustomed to forums. This person is not here to have an intelligent discussion and there is no way to help her learn how to make a right and usefull use of this tool and the presence of other human beings inclined to help each other etc. This is call a troll, this is FOR REAL a dirty shit spreading in all the forums of the world. For real I mean this is for real causing real trouble to nice people for absolutely no good counterpart at all, destroying the chance to share and build together, trampling on respect and love just for the very shabbiest personal pleasure to watch people struggle with their mean behavior. It's nothing funny at all even if it's called by the funny name "troll". But unfortunately there is almost nothing to do to avoid troll or get rid of them, best way we all agree to behave with these pests is NOT TO FEED THE TROLLS. Mean don't give a shit to whatever he says and that's it. Starting by NEVER answering. Just don't worry, everyone knows he is and pity him. Only reason why no one came at your rescue here is not we don't feel sorry after his stupid words against you, but reason is, we know we should not feed the troll, anywhen anyhow.

More nonsense passed off as naivety.

Here is another stalemate position, i ran into in one of my games (i am recalling this from memory. but the position was close)

This was a blitz game. I was black.

Here my opponent resigned, seeing that lall 3 of his pawns were going to fall. 

But after he resigned, i looked at it, and realized there was no way i could win this! 

Because even if i win all 3 of his pawns, i have the "wrong color rook pawn." Which means the best I could acheive, was stalemate!!

He had resigned, in a drawn position!

Had he worked on his endgames a little more, he may have caught that, and saved the game.

Well, I certainly wouldn't resign as white in that position... because I can't see that all 3 white pawns are going to fall.

draws/stalemate should only occur with repetition.  if i have more material or points then you then i should win in the original posters position.

"Should"? Are you, Zombiemaster, talking as if you were an authority for everyone?

Please let other people who agree on chess's rules play their rule and if you don't like these rules, go play another rule, no one will blame you or tell you HOW you SHOULD play.

I recommend learning how to play. That is simple position to avoid a draw in. There are far more complex scenarios that can dishearten the best of players. 

It is part of the game...

Think about it like this, if the white player was allowed to move again after the move that would have been stalemate, and they cannot take the black king. Then the game ends and it is a draw.

Bottom line is that these rules are rules and you should learn about them or play a different game. Complaining will do nothing as these rules have been here and been supported for hundreds if not thousands of years.

Is this another thread about why stalemate should be a win?

rules can be changed, to just say "rules are rules if you dont like em play a different game" is just plain stupid.     if you took this mindset then we would have never progressed beyond shatranj, and let me tell you....chess has come a long way with the rule changes. why all of a sudden are rule changes pariah?

Even if they can be changed, the rule that stalemate should be a win for the person who triggered the stalemate is illogical for chess. Chinese chess and chess are two different things.

And only if the OP learned more about the Chess game. Maybe if that happened, all this useless quarrel could've been avoided.

Given that, I suspect trolling was involved.
