How to draw by threefold repetition?

I again forgot how this works.

This happened again to me in the game

Somewhere about moves 65-66 the "draw" icon appeared for some time, but I had no chance to click it and it is disappeared, so when I clicked the button it looked like I proposed draw when my idea was to claim in bu three fold repetition.

How exactly this works? Why this icon appears for such a short time and why disappears if we had three fold repetition and I didn't make a move?

You can set Claim draw on threefold repetition automatically under https://lichess.org/account/preferences/game-behavior
Or you need to click the offer draw button before you make a move that will repeat the position for the third time and then make a move.

Just try to win or lose. Drawing is nothing.

The position after moves 62, 64 and 66 are identical. That's the repetition. And as black, you were the one making the repeated position. If you want to claim the draw manually (as opposed to letting lichess do it for you like #2 suggests), you need to offer a draw prior to making the final repetition. Then, when you do make the move, lichess changes the draw offer into a draw claim, and the game ends. If you wait until after you've made your move, the opportunity is lost.

This is because in the FIDE rules, the draw claim is supposed to be made after writing the repeated move on the scoresheet, but without making the move or hitting the clock. That's impossible on lichess, so the above (confusing) method was created.

Note that if your opponent had created the repeated moves (or we were discussing how white could claim a draw in this game), the discussion would be slightly different.

With regard to the draw icon that pops up, that happens when threefold repetition appears on the board, and it stays there until a move is made that makes it no longer a threefold repetition position. Often, repeating is mutually chosen by both players, so the draw icon stays up. In the case of the OP's game, the opponent quickly made a nonrepeating move, so the icon disappeared before it could be clicked.

Specifically, this setting: https://lichess.org/account/preferences/game-behavior#claimDrawOnThreefoldRepetitionAutomatically

I have mine set to "When time remaining < 30 seconds" which I think is a good setting.

Thank you so much! This is exactly what made the difference.

Really crazy choice from developers to have by default different behavior for the same feature. I got crazy trying to realize why sometimes it draws automatically and why sometimes with the same conditions it doesn't. This "When time remaining < 30 seconds" by default is a great setting to make any user out of his mind. I can't imagine any such option in any other software. It seems the lichess is again ahead of the entire planet!

Draw against much more rated opponent is like a win. In such games I even happy to increase amount of moves I can resist from game to game, not speaking about drawing.

At the end of the day, chess is a draw game, at least as proven at the moment by classics.

Thank you so much for the detailed explanations. Despite the fact that my problem was with this "crazy" choice "When time remaining < 30 seconds", your input helped to get this better and solidify, I hope, finally.

And these FIDE rules is why I play chess only on PC. Using clocks hard, writing disturbs, but this crazy amount of "aside" rules totally kills fun for me. :)
