Chess.com Does Not Know the Rules of Chess

I have always thought in a timed game (1,3,5 minute)...there is no draw due to repitition.

Someones flag will drop before the others, right ???

The game I'm thinking about wasn't even repitition...I was moving to different squares after every check. But the server dispensed a Draw based on repitition ???

Off topic...but, anyone know why game server is unavailable ??? Another Chess server meltdown ???

6bit

There is another rule (the USCF labels their version "insufficient losing chances").  The rule allows a player short on time to stop the clock before the flag falls, and request that the game be adjudicated a draw.  The rule requires that checkmate be forced rather than possible (the criterion following the flag drop).

Since this rule cannot be implemented on Chess.com (you cannot stop the clock and request adjudication), it has been incorporated into the Chess.com insufficient material rule.

That rule is also only available in USCF OTB in time controls without delay or increment.

In OTB, triple-repetition and 50 moves have be claimed. In order to make a claim, you have to have a complete scoresheet, or the TD/arbiter has to observe it. In a quick or blitz event, you don't have to keep score, so that may be what you are thinking of. However, with online chess, the score is kept automatically and the draw can be claimed as it it is trivial to verify after a claim by a player.

By the way, if you are talking about here, you only had one draw by repetition and it was obviously repeated. The queen jumped between the same two square and so did the knight; nothing else changed.

You're right.  But with time delays or increments, the game will eventually meet the 50-move rule criteria.

Also, FIDE has made this rule (Appendix G) optional, and I think that the USCF rule applies only when analog clocks are being used, and the preferred solution is to substitute a clock with a time delay or increment.

So programs are written to make simplistic judgements that are equivalent in 99% of games.

Exactly. bb_gum has nailed it.

The rules here on chess.com are a hybrid of USCF insufficient material rules because it is expedient to do so on a website.

The article was written (not by chess.com) about OTB tournament play arbiters. Completely different subject.

not too difficult.. Only use an implemented program that calculates wheter it is forced mate or not..... Like in V3..

Which take extra resources for each game requiring it. Certainly doable but depending on the server load, might not be worth it.
