Why chess.com software does'nt support Draw due to repititive moves?.I was in similar situation onlce playing in live chess and lot of time is left on the game. I wanted to draw but my opponent doesn't wanted because of the position.And I felt this was ridiculous situation.I dont know why live chess.. doesnt have this option where in some other site has already adapted it ???

I just claimed a game on draw for repetitive moves, Its not automatic, but after repetitive moves there is a button near the resign key that says "Claim Draw".  Once clicked it claims draw on repetition.  The moves MUST be identically repetitive though.

i don't know about live but one of my games on this site was automatically drawn because of repetition.

In the official chess rules, threefold repetition is NOT an automatic draw. It must be claimed by one of the players. On Chess.com, to claim such a draw, click the "Offer Draw" button. If the current position has been repeated three or more times when you click that, the game will end immediately.

 Correction: It's not the moves that must be repeated, but the same position must be identical with the same player to move three times. I know it's almost the same, but you can attain the same position three times without repeating the same moves more than once.

For example, you have a Knight on c3, and a Rook on e4 and a Bishop on g5. If you move the Knight to a2 and back to c3, then move the Rook to d4 and back to e4, then move the Bishop to h6 and back to g5, then you have the same position reached three times, but you did not repeat any moves.

Check your/your opponent's moves, count to three and offer a draw (by perpetual check.) In an over the board tournament, if no one calls the tournament director, nothing gets done.
