You have to claim the draw. If a draw is possible, a claim draw button appears
Repeated position not given as a draw
Thanks for this. Doesn't this give my opponent the chance to decline though? The rules are clear that this is a drawn position.

No, your opponent does not have to concur with your claim of a draw. If the conditions exist and you claim it, you got it. Of course, the same rules apply to your opponent as well.

deanchess, the FIDE rules require a player to claim a draw by repetition if he wants one. There is no automatic draw by repetition according to FIDE rules without any claiming. So the FIDE rules do not agree with your remark about what you had believed to be "the actual rules".

Clearly the game should be darwn automatically if 3 rd time position is repeated. The option to have to claim the draw is not following actual chess rules and I want to play chess on a site where the game actually follows the rules automatically.

Here is the FIDE rule as indicated by CM ilmago.
It is not implemented exactly as stated but the main point is the draw must be claimed. On the site, a player has to make the move before immediately claiming the draw. As described in the rule below, the player does not make the move before claiming the draw.
http://www.fide.com/component/handbook/?id=124&view=article
"9.2 The game is drawn upon a correct claim by the player having the move, when the same position, for at least the third time (not necessarily by a repetition of moves):
a. is about to appear, if he first writes his move on his scoresheet and declares to the arbiter his intention to make this move, or
b. has just appeared, and the player claiming the draw has the move.
Positions as in (a) and (b) are considered the same, if the same player has the move, pieces of the same kind and colour occupy the same squares, and the possible moves of all the pieces of both players are the same.
Positions are not the same if a pawn that could have been captured en passant can no longer be captured in this manner. When a king or a rook is forced to move, it will lose its castling rights, if any, only after it is moved."

Thirteen-fold repetition or more is allowed if nobody claims the draw.

2010 Dutch Championships: Bok,B (2430) - Van Wely,L (2653) [B43]
"The many-times Dutch champion kept repeating and his opponent did the same. Afterwards Bok said that he offered van Wely the draw twice, but his opponent simply didn't accept it."

Yes - sometimes it may be the case that a position is even repeated three times and neither player wants it to be a draw! Imagine how ridiculous it would be in that situation to stop the game and declare it a draw and in a live situation - not only ridiculous but impossible to enforce!! Who other than the two players would know the position had repeated and often even they may not have noticed!!!! LOL as a little rule of thumb I think it is always best to check your facts before you make bold and sweeping statements in public places, don't you?
I played in my first OTB tournament in more than 25 years last week and this was one of the rules I was sure to confirm with the tournament director. He told me that if I wanted to claim a draw by repetition I must do the following:
(1) PRIOR to making my move which would cause the repeated position, to write down my move (BUT NOT PLAY IT)
(2) Announce to my opponent that I was claiming a draw by repetition of position.
(3) Press the clock.
My opponent could either accept the draw or stop the clock and call for the tournament director, in which case he would play the game back from our scoresheets and adjudicate. This is why it's important to keep an accurate and legible scoresheet.
As it happens I blundered in a slightly superior position and lost so it was moot anyway
I am currently playing a game in which an identical position has occurred three times. I was expecting this to be declared a draw, but it hasn't been, and my opponent has now played a move which breaks the cycle. I have requested a draw, and am waiting to hear back from him, but usually the system deals with these automatically. Can I get the draw given before I run out of time for my next move if my opponent declines? I am in a losing position, but thought that I had forced the draw.
