Sandbagging

Sandbagging on a Go server (or in an over-the-board tournament) is deliberately setting your rank lower than it should be.

Jan De Wit wonders: what's the point of doing this? Surely it is not to increase your rating by winning lots of games; just setting your rating higher should do the trick. And if it is done only to avoid defeat, why not play at the Hippo's Room at Yahoo or some other low level server?

It makes me think of the motto of War Games with a twist: the only way not to lose is not to play at all :-)

HolIgor: Players sandbag for different reasons. Some like to win, some think that they are teaching and in some cases a pool of players that play mainly each other is formed and thus nobody makes progress. On IGS the number of double-digit kyu players is comparatively small. The median of the strength distribution is 2k. This means that half of the total pool of the players is at least that strong.

It is very naive to think that if you set your rank as 30k you'll quickly get to your true strength. It takes a lot of games (20 or more) to progress one level. You can estimate how many games a person has to play to progress by 10 levels. And if there are several runners like this they will make it difficult for each other. Still I believe that by the mere number of games people play on the Go servers their ratings are more accurate than in the real life, where you play two games per week in a club and sometimes in the tournaments. Mainly your rating is estimated by stronger players.

Grauniad: Relative ratings between players on Go servers may be more accurate than in real life for the reason you give, but there is a problem with the absolute rating because of the difficulty comparing with real life, as noted elsewhere on SL. (What am I saying: That the Internet is not real life? :-)


(moved here from "SandbaggersOnKGS" --Arno)

Scryer: Is it possible to sandbag on KGS, given that your rank is estimated by the server rather than by guessing it yourself? I started out losing some games because I wasn't used to the clock, and am gradually working my way up to what my strength was over the board 30 years ago. However, even if it's still showing me three or four stones worse than I think I once was, that may be a fair estimate of reality because I'm *still* not comfortable taking less time than I need to study a position, and I'm rusty to boot. Are KGS sandbaggers people who deliberately lose games to drop their rank? To what end?

Cheyenne: Well.. there are people who keep their rank's low by either deliberately losing the game or by resigning. As for their motives, I couldn't really tell you.

One way to help identify a sandbagger (not saying this is a fully accurate method) is to look at their rank graph (on KGS it is part of their info). If the graph is fairly flat for a long time, then look at their games and see if they are alternating winning with losing games or if there are games that are resigned. As I said not a foolproof method, but it might help one at least know what they are getting into in a game.

And.. on the flip side (is there a flip side?) a request to sandbaggers.. please at the end of the game do a review and help the poor mark with their game.

I did have one good experience with a sandbagger (well maybe he wasn't a sandbagger).. a player of about equal rank (at that time about 17 kyu) joined a game I had up (I was white). After the opening my opponent proceeded to just slice me to pieces. I finally asked "okay -- how strong are you really?" at that point he resigned and then went into a review and then set up a teaching game. Turns out he had been playing for over 40 years. He said that he was a go gambler.

Blake: I disagree with the rank graph advice. My rank graph is fairly flat, but that's because I go for a long time without playing sometimes. Then there are the people who stall out at a certain rank and don't improve from there. And checking to see "if there are games that are resigned?" I'm not sure about that. Maybe if a majority of his games are resigned, I can see a problem, but when I'm losing, I usually resign. By your advice, I would be denied a game :P

Cheyenne: As I stated... it's not foolproof, and the flat graph basically is a flag to go check their game record

mgoetze: Well the only time I played a sandbagger, as far as I know, I just opened up a rated game (as a double-digit kyu) and i got an offer from a 1k at 6 stones. So I thought, hell why not. Well he totally took me apart, I resigned and he told me he was actually a KGS 4d. Wasn't really surprising to me because the speed at which he had read out the killing sequences was truly amazing (a 1k could probably have made the same moves, but not quite so fast). Well, no harm done. :) But I suppose I might have been a bit more upset if I had been expecting to have a fair chance to win the game.
