  3. Bug. Game suddenly ended in a draw. No repetition and no 50 moves rule violation.

@nayf: Here is an explanation of 50-moves rule:

@Teslamesla I agree, there should be some notification after the game. Maybe also a warning when you have played 250 moves, as it's not a standard rule of chess.

@thibault we would suggest to implement a notification for players before they reach "artificial" limit (300 moves) and to implement notification of the condition by which draw is set (e.g. 50-move rule, 300-move lichess restriction, etc.).

You have your 300 move notification now.

You are not *required* to take a draw after the 50 move rule, or the threefold repetition rule ... you *may* declare a draw, but if both players want to continue, they certainly are allowed to.

The arbiter is advised to declare it a draw after 75 moves. The arbiters I know would certainly do.

#1 We're not going to change the code for reasons like this. Thanks for your feedback.

Why don't people holding some official Lichess capacity identify themselves as such when intervening? It's enough confusion that they too have pseudonyms.

An idea is to queen your pawn instead of meaninglessly moving your king around

It's the internet. One has to have anti-trolling mechanisms. The longest game known in the history of chess was about 270 moves long.

The ruke itself: The fifty-move rule in chess states that a player can claim a draw if no capture has been made and no pawn has been moved in the last fifty moves (for this purpose a "move" consists of a player completing their turn followed by the opponent completing their turn). The purpose of this rule is to prevent a player with no chance of winning from obstinately continuing to play indefinitely (Hooper & Whyld 1992:134), or seeking to win by tiring the opponent.
