    That is a good question, and I'd enjoy hearing some serious suggestions.

    Personally, I'd think of it as a challenge to catch him. One ideas involves sabotaging his gear with some powerful portable electromagnets, and see how he plays then. There are probably "spy" shops that might have some better ideas.

      Apparently his ''super-powers'' don't work very well when his games aren't displayed live, so It might be the simplest solution.

      If I caught someone playing like this while I am a TD, I would disqualify him on the spot. There's no need to do further investigations...

        That can be explored in a separate thread.

        as for sandbagging:
        Big US Opens use a 1 year history and 30 points rule: "Prize Limits: 1) If post-event rating posted (one year period) is more than 30 pts above section max, limit (amount) ; 3) [for initial ratings] Under 26 game limit (amounts)"
        This requires more work for TDs :/

          In Quebec, every player has a rating index (i.e. someone who's highest rating ever is 2120 has an index of .21).
          Players with an index of .20 can win prizes in a U2000 section (if they have a rating under 2000), but players with an index of .21 cannot (no matter what their rating is).
          A player can send a request to change his index if it is not representative anymore (mostly in case of illness or ageing).

            Re: Canadian Open - Anti-Sandbagging Rule? TD Decision?

            I had sent John my post above, since I wasn't sure who else to contact. His e-mail above was the response to me. So I replied by e-mail to him as follows:

            Hi John:

            Thanks for your “best opinion”.

            Could you send the TD’s my e-mail soon?

            The reason is that I will be doing a “CO U xxxx Blog” on Chesstalk this year again. I need to do some prep work on it, and to do that, I need to know what section prize I am playing for, which directly depends on whether there is any anti-sandbagging rule at all, and if there is, how it is worded, and whether I am unwittingly caught in its web.

            Thanks.

            Bob A

            Of course, if I was to be optimistic, another reason to find out soon would be to warn all the other players in my prize section ( either U 1800 or U 1600), that I was pulling out all the stops to get first!! LOL

            So I'm hoping to get an early answer from Danny or Halldor, if they are the ones to make the final decision on any anti-sandbagging rule.

              That's a good way to avoid penalizing players who just barely get their rating over some sectional limit and then drop down again.

              If TDs want to do this with CFC ratings, they could check the "Highest Rating" listed on the Player Information page of the CFC site (I don't know if it's included in the weekly MDE)

              Felix, do you have any idea of how often players request that the FQE lower their index?

                This sandbagging rule is overly aggressive. For every real sandbagger it catches, many many innocent players get caught in this very wide net.

                  It's pretty rare that someone has a an index much higher than his rating (probably less than 5% of the players). If a 1900 rated played becomes an expert and gets an index of .20, he still be able to play in U2000 sections, simply not U1900. So he would have to lose over 100 rating points (which is rather uncommon with the FQE rating, which is pretty stable).
                  I think the FQE only had to lower the index of about 5 people.

                  The CFC rating seems to be much more volatile though, so it might be harder to implement such a system. Still, in Quebec I believe it works extremely well. In a typical mid-size (100 players) week-end tournament, there might be 2-3 players concerned by this rule, and in most cases we can see that they are indeed way to strong for their sections and prizes.

                    Canadian Open - Anti-Sandbagging Rule? - Time Frame?

                    Hi Bob G:

                    I agree.

                    A time frame is required.

                    If it was the peak rating in the last two years that was to be used to determine "sandbagging", mine would be 1740 (giving a formula rating of 1540) and I'd be able to play in the U 1600 prize section, where, unfortunately, I believe I now belong.

                    However, if it was a peak rating in the last three years, mine would be 1800, and so this time the formula would put me at 1600! I'd be unable to play in the U 1600 prize section. I'd have become a "sand-bagger"! (ouch).

                    So the decision by the 2 CO TD's will affect my section, depending on what they decide.

                      I'd personally go with a 5-year peak.

What was rated and what might have been wrongly rated. Personally, I think the calculations should be given to me or the rating withdrawn. I have no intention of playing in a CFC rated event. These days chess is on the internet.
                        All of the CFC rated tournaments (original paper copies) were sent to the National archives many years ago. I would expect that all of your CFC events are there. I spent approximately 20 hours going through old crosstables (for my own amusement) a couple of years ago. I am guessing that the old rating cards don't exist anymore.

                        I would think that Paul LeBlanc would have the power to "unrate" you (especially considering your strength in correspondence chess) if you made a formal request to him.

                          Is there an email address where I write him?

                          I have to admit to some surprise when I rejoined around 2007 to receive the magazine and that rating showed up. There were players with names similar to mine and I suspect events may have inadvertently been incorrectly entered.

                          Unrating would be the best resolution.

                            I think John Brown would win, with a drop of 470.

                            There should be a time limit, with ratings going back only 5 years or so.

                            As you said, players get old.

                              Gary, tell me when your last event was and I'll look up your rating a collection of old magazines that I have. I will then give you that rating.

                                Organizers are fully within their right to put rating constraints on prizes.
                                Having said that, it appears that my 2136 rating of 15 years ago is going to cause me grief even though anyone reviewing my record would see that I'm 300 points weaker now. This is more than a little discouraging.
