My question is why in live chess doesn´t exist draw by threefold repetation. I just played the game where this clearly should happened. Instead I lost on time because my oponent declined draw and I was using only touchpad, so I wasn´t able to move with my king fast enough. What is more my oponent comented the result of game with "hhhhhhhhhhhaaaaaaaaaaaaa". In this case is hard to avoid frustration from game.

I also show the game. I know that I made a lot of mistakes especially in the endgame but I think that I deserved draw.

Threefold repetition draw has to be claimed, if no one claims a draw, the game will not end.

Dragec's link reads as follows

In Live Chess, the "Draw" button is generally used to offer your opponent a draw, which may be accepted or declined. However, in the instance of Three-fold Repetition, you can use the "Draw" button to claim a draw, without your opponent having an option to decline.

Once the position has repeated three times, make your move then click on the "Draw" button. This ends the game as a draw.

In online or turn-based chess, once the position is repeated three times, make your move.  Now, on the screen for that game, just below the notations box there will be text for you to click on that says "claim game". Click on that to claim the draw.  This method also works for the 50-move rule, which states that the game may be drawn if 50 moves (100 ply) are played with no captures and no pawn moves.

Finally, note that in cases where the opponent has insufficient material to mate (lone King, King + Knight, King + Bishop, King + 2 Knights) a draw will be automatically declared where there is a time-out.

Thanks for the response. It is truth that unknowledge kills, in this case make me losing game.
