  • Canadian Chess Open Championship: Pairing Issues

    This past round was a complete an utter joke.

    The pairings did not follow an accelerated swiss system (players were not properly paired), and further, many sections were incorrectly paired (for example, Board #47 to #53 were inexplicably highest v. lowest seed as opposed to Swiss.

    I am unsure what the correct approach is. I attempted to argue the point with the tournament Arbitrator, Mr. Hal Bond, prior to the commencement of Round 3. I also attempted to speak with the Tournament Organizers, without success. I know I have taken the time to draft, and send, the relevant Tournament Staff a 5 page complaint outlining my significant issues with the administration of this round.

    The ripple effect it has created has severely undermined the final outcome, and it is hard to imagine a remedy that will resolve the problems that this farce of a round has created, short of replaying the Round in its entirety with the proper pairings, and discounting the Round 3 results.

    :: sigh ::.

    It's pretty sad that the biggest tournament in Canada for Chess is being administered in such a fashion.

    Re: Canadian Chess Open Championship: Round 3 Farce.

    If indeed a mistake was found or a pairing error was discovered it should have been corrected before Round 3. The excuses that players had already spent time preparing for their opponents and then find that pairings may have changed is a real crock. The organizers said it would be unfair but hey is chess not to be played over the board? I think if a major mistake has been made in the pairings it should be corrected for round 4 even if it messes up pairings for the last time.
    Let's get our act together and run a tight ship. Floundering only leads to unhappy players.

    One major question I have is what are Ghost points and why do we need them???

      Ghost/Phantom points are added temporarily to players totals under accelerated pairings, which a Wiki article explains.

        Matthew,

        I can't speak for others, but I assure you that Hal took the matter of the Round 3 pairings problem seriously. He left the CFC AGM to give it his full attention.

          I always wonder where these players who often complain dramatically about pairings got their expertise in pairings from and if they have ever actually paired any tournaments themselves. Mostly they have not since the number of players far outnumbers the number of those willing to TD in Canada.

            I'm sorry. I was totally unaware that you had to fly to the moon to understand its composition or structure. I was also unaware you had to have been in space to know the critical components of space flight.

            The Swiss System is not overly complicated, nor is the Accelerated Swiss System. Yes there are kinks that get thrown in, but the pairings were so wrong, that it was easy to spot the problems. To begin with, players with phantom (or ghost, or fake) points were treated differently than players with real points, something that is not supposed to happen, because it defeats the point of assigning these phantom points in the first instance. It also results in some players with real points having much easier matchups than they other wise would.

            Furthermore, on some boards (including my own), the seeding among real point players was highest v. lowest, second highest v. second lowest, as opposed to following a Swiss System. This was totally arbitrary, and may as well have involved pulling names out of a hat.

            It's certainly true that issues like colour parity arise in odd rounds (and are more likely to arise later in the tournament), but for the majority of players this would not be an issue in Round #3.

            The pairings were wrong. The fact that they were wrong meant the results garnered by them are tarnished, and it undermines the performance of the remainder of the tournament. It is a substantial problem.

            Oh, and for the record, had the pairings been done correctly, it is fairly certain I would have faced an even stronger opponent; but that's fine, at least then I would have played the RIGHT opponent.

            Apparently, not serious enough to fix it.

              Hi Zeljko:

              It doesn't take much to see that the pairings were screwed up, at least for round 3. Take a look at Bindi Cheng's thread further down the board. The round 1 pairings are on this board and show these two pairings for round 1:

              16 FM Bindi Cheng (2426 : - : 0.0 [3.0]) Lorne Yee (2222 : - : 0.0 [3.0])

              and

              55 Paul Leblanc (1907 : - : 0.0 [2.0]) Nick Karlow (2012 : - : 0.0 [2.0])


              The round 3 pairing for Bindi was:

              8 FM Bindi Cheng (2426 : w : 2.0 [3.0]) Nick Karlow (2012 : b : 2.0 [3.0])

              The number in the square brackets is the point total, including phantom points, to be used for pairing purposes. Somehow Nick Karlow picked up an extra phantom point between round 1 and round 3. (I don't have the parings for round 2).

              Several years ago I played in a 4-round tournament. I played white in the first game and then was given 3 straight blacks. When I complained, the TD cheerfully told me that that's what the computer came up with so it must be right. The knowledge issue works both ways, although in this case I don't know what's going on since Hal does know what he's doing, but it's clear the pairings have not followed the announced system.

                Here, you want a more dramatic example?

                22 GM Vladimir Malaniuk (2551 : w : 1.0 [2.0]) Helmut Fritzsche (2005 : b : 1.0 [2.0])

                53 Patrick Yu (1572 : w : 2.0 [2.0]) Mei Chen Lee (1552 : w : 2.0 [2.0])

                Why is Yu playing Chee? They both have 2 points.

                Further:

                46 Alexandru Florea (2076 : w : 1.0 [2.0]) Henry Gonzalez (1077 : b : 2.0 [2.0])
                47 Matthew Scott (1506 : w : 2.0 [2.0]) Ferdinand Supsup (1851 : b : 2.0 [2.0])
                48 Ed Zator (1835 : w : 2.0 [2.0]) Tian Lan (1510 : b : 2.0 [2.0])
                49 Pino Verde (1800 : w : 2.0 [2.0]) Bryant Yang (1500 : b : 2.0 [2.0])
                50 Jack Maguire (1513 : w : 2.0 [2.0]) Bruce Dowling (1796 : b : 2.0 [2.0])
                51 Genadi Medvedev (1628 : w : 2.0 [2.0]) Samir El-Gohary (1541 : b : 2.0 [2.0])
                52 Razvan Preotu (1606 : w : 2.0 [2.0]) Jatinder Dhaliwal (1577 : B : 2.0 [2.0])
                53 Patrick Yu (1572 : w : 2.0 [2.0]) Mei Chen Lee (1552 : w : 2.0 [2.0])

                Those are the players at 2 *real* points between 1500-1900. I don't know if anybody higher or lower has 2 real points.

                Gonzales, on Board #46, is 15th among them.

                That left the inexplicable pairings, among "real point players" of:
                Board 47: 13 v. 1
                Board 48: 2 v. 12
                Board 49: 3 v. 14
                Board 50: 11 v. 4
                Board 51: 5 v. 10
                Board 52: 6 v. 7
                Board 53: 8 v. 9

                That's blatantly wrong.

                  53 Patrick Yu (1572 : w : 2.0 [2.0]) Mei Chen Lee (1552 : w : 2.0 [2.0])
                  If you take a look at the round 3 pairings before and after the one of Florea vs. Gonzalez, you will see that they have paired all of the "1+1" (one real point and one phantom point) players together and then paired all of the "2" (two real points) players together. That makes no sense.

                  Even if it *did* make some kind of sense, I can't figure out why Florea would be playing Gonzalez. It's like they decided that the lowest of the "1+1" group should be playing the lowest of the "2" group.

                    I realize your comment wasn't directed at me, but so you know, I did take a look at it yesterday and I was aware of that.

                    In fact, so was Hal, since I brought it to his attention by 1pm (I had informed him as early as 9:45am that there was a problem with the Boards 46 through 53, but I hadn't, at that time, noticed the extent of the problems).

                    The problem is, it was wrong on many levels.
                    1) 1+1 group wasn't playing 2's.
                    2) 2's were paired wrongly with the 1+1 (re: Gonzales) even if they wanted to do that.
                    3) 2's were paired wrongly amongst each other.

                      In a separate thread Bpb Armstrong points out (and I presume he would know) that the pairing mixups seem to have been caused by glitches in SwissSys - something about a recent change to implement 'accelerated pairings' [notice the lower case "a" Jon]

                      As the story goes, when the glitch was tracked down it was decided (I guess by Hal and the organizers?) that it might well be worse to change the pairings than to let them stand.

                      Regardless of the cause and the analysis, I would have hoped there was a proper announcement before the start of Round 3 [I would have delayed the start, if necessary, for the few minutes it would take] of the relevant details so that people would at least know exactly what did and did not happen rather than having to speculate.

                      Well before the tournament I and others had asked what sort of pairing system would be used and all I ever saw in response were vague statements; pairing rules HAVE to be clearly stated so that everyone can at least FOLLOW them to believe they are being properly implemented.

                      Unfortunately, if there are 213 people in the Cdn Open there will be at least 1+213 opinions on how to do it or how it is being done...

                      It seems like Round 3 is in the can and all that can be done is to move on...

                        No problem. After I had made my first post I went to take a look at the Florea-Gonzalez pairing and saw how that was messed up and when I can to edit my original post and take on a "P.S.", you had already replied. So I just replied to you instead of editing.

                          There was an announcement that the pairings had "anomalies", the problem is the tournament organizers were content to not alter the pairings despite having more than enough time to do so. Hal was aware of the problem as of 1pm in the afternoon. There are 130 boards. He could have repaired the 260 players in 5 hours. He may not have wanted to, but he could have.

                          The problem now is, every subsequent round is affected by the errors in that round. Players who shouldn't have won, have. Players who shouldn't have lost, have. Further, where before to go to 4 points, you'd need 2 wins over superior opposition, now some players only need one.

                          Say I had won my game, for example, playing 350 points up. Now I would need to repeat the performance in Round 4 to get to 4 points. By contrast, a player who was 1570 and played another 1550, would only need to perform at that superior level once.

                          The entire tournament has been rendered inequitable.

                            A pairing officially made public shall not be changed unless it violates the absolute pairing criteria (B1 and B2)

                            1. Two players shall not meet more than once.
                            2. A player who has received a point without playing, either through a bye or due to an opponent not appearing in time, shall not receive a bye.

                            B.2

                            1. No player's colour difference will become >+2 or <-2.
                            2. No player will receive the same colour three times in row.

                            For me, it is more interesting to know: was it a software/programmers glitch, a human error (ghost points +/-), both, or smth else?

                              You needn't have flown to the moon Matthew but if its a choice of talking to you or Neil Armstrong when he was alive I'll put my trust in Neil everytime. So you've never paired a tournament ever, good to know. You also apparently needn't have gone to drama school to be overly dramatic. Oh and I was talking about chess players in general. Its not all about Matthew.
