Perhaps he enjoys to drink some beers while playing blitz... losing a lot of games on a day is not so weird, because sometimes you are tired or listening to music, phoning and playing table tennis while playing a blitz game.
I think that losing on purpose is not legal. Losing to 600 is very strange even if you are high on drugs etc. ;-) I geuss you should contact an admin if you want him to be punished.
Cheers,

It would sure help to start by mentioning his nickname...
Putting off a win/loss to try and save rating isn't necessarily against the rules as it is unsportsmanlike and rude.
If you feel like he's doing something against the ToS then use the Report Abuse function at the bottom of the page and the staff will look into it.
Maybe he resigned from a tournament?

I wouldn't say that's necessarily a sandbagger, it's a case of getting screwed by Glicko as it only factors K for the person with it sliding and not for the opponent. What I mean by that is that if you play a brand new 1200 and lose to them, instead of having no rating adjustment for you, it's adjusted like you lost to a 1200 instead of losing to an unknown entity. One of the many problems with Glicko. As an afterthought, with no ad hominem intended, how does a B player know what "tactics of an expert" are? 
Sandbagging suggests that some players want only to win lesser class trophies a lot.... That they are losing to maintain a lower rating (good for them)__Yes / NO__ The most of us would like to gain a better rating (bad for us) because it's a struggle just to compete! So, sandbagging, it seems is for inferior or inexperienced players with little or no skills! If we do not learn or study chess, we tend to fall down and stay down. Therefore, such opponents will always penalize themselves with a lesser rating..... So, I personally feel that calling it "sandbagging" is fair, but, taking action against (to penalize) such a player is unfair. We are not all real chess "tough" (chess competent) until we are gaining above average class rating skills. Maybe , they should be ignored for now - give or take a couple of years of play anyway ..................................................................... They may learn something by then !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Why dig up a thread from 2009?
Sorry for the lengthy comment, but, I was in this particular tournament ["No Sandbaggers Allowed", Dec05, 2010,"] when I first began playing here on chess.com and such made me feel so accused of cheating that I could not enjoy the tournament (what so ever). I had not played chess in decades gone by, and, just when I needed to gain some skills (losing a lot), I join in this got damn tournament! Sorry bout that...... Go Figure!! I other words, I had not any real chess skills - simply "Bad Timing" on my part (hurt my heart)!
Good comment "verylate". This tournament "No Sandbaggers Allowed", Dec05, 2010, (I was in) was very light weight in ratings (<<2000) compared to such players / opponents, in that day and time, who were able to predict or not how the outcome of gaining a prize would be! But, because of money needs (past or even the present), I see where this is going. I understand: ""Suspected Sandbaggers MrEnigma | Jan 3, 2011, 7:52 AM __ If anyone suspects another player of sandbagging please send me a personal message, and I will remove them from the tourney. A couple of people have caught my eye already. kind regards to all"" ......... We are playing for site trophies - not actual money [why so serious] - weak players are of the site. Stop accusing players of cheating!!
Cheating for money is one thing, still, cheating for a mere chess.com trophy is for them of little wisdom!! Tournament Directors need to slow there roll on this one subject...... They are chasing away / removing paying customers of this site. One other thing, a lot of members of these sites may or may not have real time to play serious chess all of the time...... maybe punishing the wrong members - skills or no skills!
Negative (not), my response is based on members who wish to learn chess because whatever particular rating these cheaters may have is something that is not pointed out. Are they 2000 - 1000?! So, are we talking of cheaters "low rating" or cheaters of "computer use" or cheaters of "high ratings" or some members that are known to have had high ratings ("very high perhaps" - 2000+) who may actually know what they are doing!? __Just does not make sense to pursue__
People would probably stop calling other players cheats, when the cheating players cease to cheat. I literally had 3 confirmed cheats in an arena tournament. Next day their accounts were banned.
I report anyone I suspect of cheating...I was eventually forced to take up an active position on this because it was just so prevalent. Unfortunately, I do not see these people in real life, otherwise, I would handle it person. On the net though, gotta just report them.
Too many people are cheating these days. I do not trust anyone anymore. 800 rated players playing like GM's. Absolutely ridiculous.
A few years ago a member here messages me asking for help, and "can we play an unrated game?" That kinda stuff. So we play an unrated game, and he plays like a beginner. We went over some things, and he asks if we can play a rated game? Since i particularly don't care about my online rating, I had no issue with the request. Well...He beat me like a read headed step-child. Proceeded to brag in the forums, and pull the usual: "What a patzer...." "What a fish..." "This guy sucks..." etc. Why do people do this? You can use the usual reasons, but it won't change anything. Welcome to the internet,.
Such, my friend, is where inferior & superior players use computers or owners of chess engines may be gaining knowledge of what their computer / engines are capable of.... Well, the ability to detect such a thing is something I never considered until now - I wish them administrators "Good Luck with such" is all I have to say! Goodbye! Still, sandbagging is where I wonder - trying to understand who cheats for a mere trophy!
Good Point Sir! I often wondered why some members go after other members after they refused to play a rematch (cussing, bullying, etc..) even if they had lost and lost the other player's curiousity. Should be no shame in that. Seems, that we have members who need that certain kind of attention when playing chess! Perhaps to intimidate there opponents! __They will stop at nothing!?__
Maybe depends on their type of lifestyle (religion, nationality, etc........).

Yup......There are some tremendous douchebags on these boards. I have the chat on mute always because of the amount of people chirping and acting like assholes in a game. If we are OTB, I guarantee you no one would say the things they say to me in an online game behind the safety of their moms basement.
And that is what we need to keep in mind. 99.9% of this stuff only happens online. The internet is like electronic beer.
What is the restriction period for sandbaggers?
What is the restriction period for sandbaggers?
No clue
I am playing a game of chess in a tournament. The first game against this player, his rating was around 1500, mine at about 1680. He pulled off an upset after I played poorly. So my rating went down some and his rating went up some. Great. The second game, his rating started at about 1550, mine at about 1660, and as the game has progressed, his rating has dropped dramatically. Right now, my rating is about 1630, his is about 1100, when literally 10 minutes ago, he was at 1300, and several hours ago, his rating was 1440. I have a feeling that he is sandbagging just to win back a ton of rating points as he is winning this second tournament game against me, and to kill my rating. I looked at his history, and he lost 8 games TODAY!! Several of them looked like either the opening or middlegame, and he RESIGNED AGAINST A 600 AFTER PINNING THE OPPONENT'S QUEEN TO THE KING!! Could someone please check and make sure that this is legal?? I'm sure that some of his losses and wins were real, but eight losses in ONE DAY!! That looks so artificial.
