  • Re: Canadian Chess Open Championship: Pairing Issues

    I don't think you can compare an average chess player participating in a tournament as equivalent to an average golfer playing on the PGA tour, or star hockey player.

    There are massively divergent interest levels in the respective activities, and to some extent it is the fact that these top people in other fields *attract* audiences that make it unique. It's not like that in Chess.

    Just because you're a 2300 doesn't mean I care any more about your game than anybody else. Hell, I'd wager most younger chess players don't even care about the Olympiad or any other World Championship type events.... unless they, themselves, were participating.

      I agree. Hold on to that thought. But it doesn't mean that Olympic team members should play in the Canadian Open:

      On the surface, at least, the best way for players to get to know team members would be one where this direct competitive aspect is absent, a cross-country tour, for example. There's no problem getting players to give tours, but a lack of organizers.

        A simul vs all 10 team members, with them taking turns making the moves and not allowed to talk to each other, would be interesting ;)

          EDIT: I should add that these pairings aren't grossly wrong, there might be a reason for it unlike the ones in Round 3. I just can't figure out what that reason might be.

            There is no rule you should play against people who match your rating nor that there should be a balance. The avg rating of 4 pointers is 2000, and that's also who you are playing. While you might have been paired different, it's not likely it should be easier.

            I think you complain too much. Instead try happiness at your good result. Your score far exceeds your rating. Now enjoy your opportunity to learn from a good player.

              I just want to know why the pairings were switched, that's all. I do have an entitlement to know that, it's not unreasonable. If the explanation is something like "well, player X had already played player Y, so we had to switch X and Z" then that makes sense. Transparency and credibility are important when people are investing a lot of time and effort into something, two characteristics that have been sadly lacking in this tournament.

              Especially when some of my competition in my category has similar scores (albeit, because they utilized byes), to wonder about these things.

                Hi Matthew:

                I'm not sure why you are paired where you are either. Assuming that board 55 represents the last board with a score group of 4, then I would have expected you to have been on board 54 or board 55 given your rating relative to the others in the score group.

                The colour switching may have been unavoidable. In the case of your specific pairing it's proper that you should have white since normally the higher-rated player gets his due colour.

                As to why you got that pairing, several things are possible:

                1. A player in score group 4 withdrew after the pairings had been run through the computer and the organizers had to make a last-second manual change.

                2. A player in score group 4 had requested a half-point bye for the round but they were somehow included in the pairings anyway, again necessitating a last-second manual change.

                3. SwissSys is using a "look-ahead" method to avoid potential pairing issues in the final round, although the possibility of it affecting your pairing this much is pushing it.

                I've seen both #1 and #2 happen a lot.

                  I get that, but it's just, given I already was the downfloat last round in the 4 point group, it's really adversely affecting my title chances in the U1600 or U1800 categories... Which is frustrating. Average opponent strength (discounting my Unrated Round 1 opponent) has now broken 2000, despite not playing someone over 2000 until Round 5.

                    I believe you are seeded by tie-break scores. You would have a much higher tie-break than your peers.

                      Hi Matthew:

                      I forgot to mention that (I think) SwissSys has an option for doing pairings (in a score group) not based on the players ratings, but ranking them based on their performance in the tournament. I may be wrong and it may be some other pairing software that I'm thinking of (SwissPerfect?). In any event I don't care for that since it means that the ranking of players within a score group, for pairing purposes, changes with each round. Jonathan Berry would know more about the wisdom and/or pitfalls of applying such an approach.

                      Another reason I don't like it is that it can *only* be done by a computer pairing system and that makes it a lot harder to a) explain pairings to players and/or observers; b) harder to manually check the validity of pairings.

                        That won't help me though when my opposition (U1600 or U1800. Take your pick) gets to either 4.5 or 5 via:

                        Anyway, I'm going to get get ready for my game, and do my best, as I have attempted to do all tournament. It's just frustrating at the lack of transparency, and it's difficult to rectify the fact that despite having a performance rating of over 2000 to date in this tournament, this pairing is going to really hurt the chances of winning my category.

                          Why am I paired with such a good opponent again? I'm not even supposed to get White this round, so it can't possibly be for colour reasons. Also, as the Downfloater in the previous round (and having to play a FM as a result), I thought that you had a limit on how many times you'd get flipped around the pairs.

                          EDIT: I should add that these pairings aren't grossly wrong, there might be a reason for it unlike the ones in Round 3. I just can't figure out what that reason might be.


                          No doubt, you have asked the TD before posting/complaining here. What did Hal say?

                            Actually, I pretty much simultaneously sent an email - and he has not as of yet, responded. My question was directed towards transparency in the process, that's what I asked Hal for.

                            I wondered if someone here might have some idea. I've seen a couple suggestions. They're possible. I don't know. Of course, the problem is, there's this double standard in this tournament that the pairings can be however screwed up as they want, and there's not a damn thing you can do about it apparently (as Round 3 was evidence of)

                              Sigh.

                              Anyway, I'm going to get get ready for my game, and do my best, as I have attempted to do all tournament. It's just frustrating at the lack of transparency, and it's difficult to rectify the fact that despite having a performance rating of over 2000 to date in this tournament, this pairing is going to really hurt the chances of winning my category.

                              The lack of transparency. I return to that.
                              you want the organizers to give a personal explanation to each player who questions the pairings? on the basis that they don't like them, or don't understand them, or they could be different?

                                Given how badly they were screwed up in Round 3, and how anybody with half a brain can tell that a low ranked player in the middle of a given score group is somehow playing above higher ranked players, in contravention of a Swiss System, then yes, I think that player is entitled to an explanation.

                                It's not rocket science. I may not understand why I am there at the moment, but I certainly understand that under ordinary conditions I should not be. Therefore, explaining what the extraordinary circumstances are is perfectly reasonable.

                                Responses like the one you offer is superb evidence why tournament enrollment and CFC membership is down. I can play chess quite fine without ever needing to spend my time and money in arbitrary setups.
