What exactly is a "dirty flag"

What exactly  is the difference between that and a non dirty flag ?

Just wondering

Dirty flagging is playing from a losing or drawing position and then winning because your opponent's time runs out - usually by throwing in extraneous or sacrificial checks to force your opponent's time to run low.

Lol thank you.........that is what I thought

I was dirty flagged then, ah well part of the game I guess.

Dirty flagging is common in bullet games, but it also happens in blitz and rapid if time is critical...

No, it was not you..it would be rude to name the person, I just wanted to know if it was as I asked, that's all

Well I was about to win his queen or mate him ,so yes, I think I was winning lol

Hey ,you just played him as well

Question, this happens to me...and I'm not trying to play dirty. But since time is a consideration...if you take your time to strategize, you risk your control time. That's the whole idea of blitz games , right? I win a lot on time...however...that's not how I would prefer to win.  But it happens.

So If you're down material and not going to win with a mate, you wouldn't resign in a blitz match would you? What is the proper thing to do? Sometimes I get down quite a few points, but I also move fast (which is probably why I'm down material)...should I just quit? Don't understand how it can be a dirty flag ever if, at my level, the GMs say never resign...but I'm just running. Sounds like running and/or sac'ing pieces is looked down upon in this thread. I watch GMs play for draws or stalemates...is that just as bad?

I never go into a game with the intention of winning on time, but I'll run if I can. 

I think the distinction is if the opponent just plays much too slowly, mismanaging their time, and losing as a result, that’s not really a dirty flag, that’s just them losing on time.

By contrast when it’s a mad time scramble, and you’re doing everything you can to tip them over the edge and make them lose on time (which you absolutely should do) then that would fall more into that category. 

play enough bullet games and it’s only a matter of time before you win a game with 0.1 seconds left on your own clock - satisfying when you’re on the right side of it, annoying when you’re not  

I have had that happen to me plenty of times.

Some valid points in this thread and I would not disagree.

Personally, I am okay with being dirty flagged on because it’s within the rules. I am fast in the opening and end game but, slow in the middle games; that’s all on me.

I got a second wind in playing blitz and bullet again because it’s a great opportunity to experiment, learn and not be overly invested unlike playing rapid or classical.

Agree with the definitions given, from a position of no hope to win on time is a dirty flag. I don't think it's an insult really - more recognition that when you win like that it feels good, snatching victory but in a bit of a naughty way

dirty flagging is also an art

A dirty flag is a flag that needs cleaning.

that's how I feel about it. When you checkmate someone in that amount of time, it just makes it extra juicy because you were good AND fast. Believe me, I've tried just playing fast, but since I'm not good I get caught a lot. Flagging someone on a 30 min game...which has happened...is totally their fault.

Dirty flag can be claimed as a draw in OTB games with longer time controls. But:

- you need to claim it when you have < 2 mins on the clock (and some time remaining)

- your opponent is actually not trying to win (note it does not matter whether the position is won for you, or drawish).

Does flagging someone in Classical Chess count as dirty? (90+30) I was losing by the way. Think my opponent got tired because we were in the 4th hour of play...I don't think any game with 30 second increment you can really count a flag as dirty, as your opponent has 30 seconds increment so if they flag it really is their fault. 

@Daarzyn7...good to know; wasn't aware of that rule. But in such a scenario, how would you prove that the "opponent is actually trying not to win"???

I wouldn’t call it a dirty flag. It’s very rare to time out in classical time control so it’s on him.
