    The same goes for all your competitors.

    Late in the tournament it's too late for this corrective effect, but early on there's lots of time for balance to take place.
    It doesn't though. I have 3 - my opponents have 3.

    To get 3, I had to beat a 1900. To get 3, they had to beat a 1550. How does that "balance" out?

      Or did they get it the wrong way around?

            And, on the main page (in rather small font):

            "SwissSys is making life easier for frazzled tournament directors."

            Maybe there should be a footnote: "Hal Bond excepted" or "YMMV"

              The solution would rather be to have two sections ; the Open one for the few norm seekers and players who wants serious chess, and the other one for those who can't figure out accelerated pairings.

                  "SwissSys" - "FIDE norm requirements updated. (8.54)"
                  Does it mean it can produce the list of norm candidates who satisfy minimum requirements (Rp, points, titled player, etc)?

                    Because if you are good, you will continue to win, and if not you will be beaten down to your proper level.

                    And to the poster you said accelerated pairing means several wasted rounds, I think contrariwise that accelerated pairings mean no rounds are meaningless blowouts, perhaps only a handful of games. Certainly it's better for spectators.

                    ----

                    Another system I've seen in action is to give all the top players 1 point byes. Say all 2300+ get 2 full-point byes, and effectively play a 7 round tournament. Round 3 the best of the lower masses get paired up with the master class, and the tournament goes on.

                      It's been able to do that for years... it wasn't always 100% accurate though, plus FIDE does change the rules from time to time, so I assume that's what that fix is all about.

                        Those are not the same. A person can agree with one, like bringing back the death penalty, and not the other.

                        Do you envision lower entry fees for the part of the event which does not provide a possibility of winning the open championship?

                          Actually, Jean, in case of the 2007 Canadian Open, Système Suisse Accéléré Degréssif, the majority was right. If you look at the Player Survey of the 2007 Canadian Open, and scoot down to line 12, Pairings, those who replied to the survey (150, more than half the entries) found them to be 6% poor, 8% fair, 26% satisfactory, 37% good, and 22% excellent. Majority governments have been elected with fainter approval than that! Although it must be noted that the majority stood even more in favour of the other aspects of that tournament.

                          I think it shows that the real-life players took into account the whole situation, and that they accepted the personal apology I made at the beginning of the horribly late round one.

                          With Mr. Ritchie, you can't tell whether he's serious or joking. When unavoided, what works for me is to regard each one as a joke. YMMV.

                          The multi-quote icon doesn't work on my computer. I click on it, it turns pink, but nothing happens. Is that normal for everyone else?

                            Eg, only top 5 boards get actual competitive games. The rest of the games are totally lopsided. I mean If I wanted to play a 1500 so badly I'd go to any club and play some blitz games with them. I expect to have a few mismatched early pairings but this is round 5 and I already played my normal share of lower rated players. To play anyone under 2000 is quite a spectacular feat in any of the later rounds for me. Furthermore, it's not just my pairing that's useless. It's the other hundred pairings that have rating differences from about 300 to 1000. Is this supposed to be a competitive norm tournament or a competitive see who can finish their game the fastest with the most time? And I'm sure I'm not the only one with their norm chances destroyed by the pairing system and not by themselves. Thanks Canadian Open 2010, you'll always have a special place in my heart.

Whether you like Free Trade or not, you have to admit that he negotiated a pretty good agreement. Sure the Americans cheated on it, but yes, Virginia, they would have cheated on any agreement.
                              I've always been of the opinion the Americans have the same regard for their signed agreement as a cat has for marriage laws.

                              In a way, I like the model. We send the Americans all our oil and gas and they send us all their money. It has to beat offshore drilling.

                              The minus side on free trade is being played out in the B.C. (and other provinces) forestry sectors. Closing down mills and moving them to the U.S. or China to get the benefit of lower wages and taxes. Then ship the logs for processing in other countries. We are losing a lot of our industrial base that way. Not that I'm complaining. A company has to make money to stay alive and keep the shareholders happy. I've got a whack of shares in a company on the Island which just closed down a paper mill. I'm wondering where they will move that. I once took the tour of a Bowaters mill in NFLD and it was impressive.

                              I figure the Americans are using the Black Liquor tax credit to subsidize the industry. A loophole in the agreement and a HUGE subsidy, the way I see it.

                                I'm curious to know what the "official" stance is on this situation? Matthew seemed to state that he [and possibly others] brought this to Hal's attention well before the beginning of Round 3.

                                As I understand it, a decision was made to let the bizarre pairings stand - perhaps because it was easier to go with the published pairings than to override them on the computer or to make sure everyone could be informed etc. I would love to know if anything official was posted (and what exactly was said).

                                (I am not conducting a witch hunt here; I have no skin in the game(s) so I have nothing to gain either way). I of course have seen some of the pairings for Round 5 are 'unusual' to say the least. Sadly, it seems worthwhile to ask for another value on the pairing chart: namely, rating difference!

                                Anyway, if you were looking for norm chances, I guess they were slim to begin with (in a 9-round open) but now impossible? I am not sure of all the nuances of norm attainment, but I presume you are. Good luck in the rest of the tournament...
