If your oponent killed all your pieces and you have only the king left, how many moves is there for it to be considered a draw??

And is this rule followed in Chess.com??

I don't believee it's limited, i've been in that situation quite a few times and played for a long time with no draw. I may be wrong though !

50 moves or 3-fold repetition of position is a draw.  Then again, if both sides have insufficient mating material, I think the servers automatically call it a draw.

50 moves from the last capture or pawn move, so if your opponent has pawns left you could be there for a long time. 

do you know if a 3-fold repetition of a position is always a draw or only if you have limited pieces?

and is there a counter for the 50 moves??

The 3-fold repitition must be claimed as a draw by a player.  It is not limited by pieces.  If both players miss it, then it isn't a draw.  Usually, though, it occurs when someone wants to force a draw to avoid a loss.

Similarly, the 50-move draw must be claimed.  An easy way to counter it is to move a pawn or make a capture, since the draw only occurs if no pawn is moved or piece is captured within 50 moves.

50 moves is a looong time though.  unless you are playing an absolute beginner or are in an exceptionally difficult endgame, you arent likely to reach it. 

I'm fascinated by your term--killed.  I think capture is the term used.  Yes, if the opponent doesn't move any pawns--50 moves is the limit to declare a draw.

hey charlie,

I'm sorry for using the wrong term, in my native language (portuguese) the term that i learned when i first learned the game was killed. 

Watch out for the knight and bishop vs opponent king mate sequence, this is where the 50 move rule really comes into play.

 I was in this endgame trying to checkmate the king but I did not reach 50 moves, I am not sure how chess.com approaches this endgame.

well i imagine the same as any other.  50 moves is 50 moves.  However if you play it right, there is a win there because you can mate in under 50 moves from any setup K+B+N vs K.

 In my native language, we use a word that if translated means "eat"; that's worse.
