Study endgames. After studying you will be able to tell if you have a won endgame.
HOW DO YOU KNOW ?

Some end-games are obviously won while some are more subtle but still certainly won if played accurately. A super Grandmaster will often be able to tell late in the middle game if he trades his pieces he will have a 'won' endgame, Capablanca was phenominal at this. He would create a small advantage in the middle game and magically force his opponent into trading down to a 'won' endgame; genius.
Study endgames and you will find it easier and easier to differentiate between a 'won' endgame and 'drawn/lost' endgames.

By having either knowledge about through books and the like or experience from lots of loses and wins in the endgames. Usually both.

Sometimes by knowing the basics, no need for anny calculations here:
The black king can stop the 2 pawns, but when the white king helps, the black king can do nothing.
Still no need for calculations, the black king can stop the pawns, but cant take anny of them (the other one will queen) so all white needs to do is to get ride of the black pawn first, then help his own pawns.
And, how do I know that the white king can stop and take the black pawn without calculations? Basic: the white king can get in the "square" of the black pawn.
You know that all you need for a checkmate is:
1 - a queen
2 - a rook
3 - two bishops
4 - a bishop and a knight
In some positions you need to calculate:
Not so hard, but how does white win?

i would go re6 and if rxr kxr k anywhere white walks over picks off the pawn moves to g7 and controls the queening square. if black moves the rook then white gets a free pawn and should be able to queen his remaining pawn

yes, white wins the pawn endgame, but you wouldn't make the exchange without anny calculations, it would be really boring if black king could reach one of the criticale f7-f8 squares.
Draw.

Nice job pskogli!
Another simple way to "judge" your position is to count points: pawn=1 point, bishop/knight=3, rook=5 and queen=10.
But remember: this pointcounting depends on how the position of the peices on the board are.
For instance:
Black is to move, very obvious which side will win...
But, when white is to move....all those white pieces are of no use what so ever: white will mate black in 2 moves.
So, my message is: pieces on the board can tell who has the better position, but only the position itself can tell what the final result will be (when played accurate)

Another one:
Which blunder is needed (white to move) for a draw??
(this question is not ment for experienced players )

unklecyril's rating is 1948, I think he's pulling your leg.

With trading, for each exchange you are closer to the endgame.
But don't just trade down without knowing how the endgame would end up.
Long term advantages like material and space would give you a good endgame, but to trade down a active position usually gives nothing.

In my opinion:
opening: theoretic
middlegame: creative thinking
endgame: theoretic
so, when I run out of theoretic knowledge in the opening, my middlegame starts, when I run out of creative idea's, my endgame starts

My way of playing is roughly the same no matter where in the game I am.
1. I Try to understand what's going on, find a good plan, then find the best moves acroding to my plan, if I somehow find's no moves that help's my plan, I'll go back to the start. (what's going on)

I can usually tell when a player has a won and endgame by the fact they are going to mate me or promote a pawn to a queen ...... ? Generally material or position

Just to be sure I got it it's basicly who has the better position as a long as your opponent dosent have a big material gain or can't mate in the next couple of move's.

The endgame is the part of the game that off-the-board study is more important than on-the-board experience. At least it is for us lower ranked mortals who don't get into all that many even endgames.
Preparing for a fairly wide spectrum of endgame types really only can be done off-board, if you think about it.
This assumes that the player isn't rattled and can translate study to the position in front of him otb. Being able seems ordinary enough.

No i found i got into endgames because i studied openings and middle game strategies more and so wasn't getting crushed so easy. It was then that i started to find out the hard way i needed to improve my endgame, i did this through losing won games, drawing won games and so on, u can learn about endgames through trial and error. Then i decided to get a book and start making it easier on myself hahahaha.
If u don't study you get beat up by those who did.
