    Keeping in mind that many of Canada's residents are not having English as their first language, this guy should NEVER write anything for the CFC that is for general public consumption!
    Well, whether or not the problem is my poor grammar or your comprehension, we clearly are not communicating effectively. That's too bad.
    It was nice to play OTB in Waterdown this past weekend, and as usual I got a few questions about ratings. It was a pleasant exchange demonstrating in person communication is so much more effective. It was clearly a mistake to think ratings could be explained on chesstalk without hostilities.

    I am happy to address rating questions in person or email, just not on a blog. Life is too short for all this aggravation.

      It seems to me that this astounding admission from an earlier post is the clue as to why Pargat is out to lunch on rating systems! He seems to believe that a rating is some sort of absolute measure of chess ability. It isn't. It is just a number arrived at by shuffling around performance points between players you normally play with, yes the "rating pool". If one were to examine the formulae used, you would see how difficult it is to rise above the top ratings in you pool. Women's ratings are lower than men's because there are far fewer of them playing top-level chess - nothing to do with ability, possibly because of different wiring and priorities. While quite entertaining, it is a pity to see Pargat's arguments become wilder by the day, as he resorts to nasty little insults. Surely you're better than that...?

        Hello Pargat.

Let's also pretend that Hou's abilities are actually every bit as good as Carlsen's.

        That means Hou will start beating all the other top women consistently, and her rating will eventually reach Carlsen's within some margin of error, say 1%. She would become the women's version of Carlsen. Her rating will get to be the same as Carlsens, and this means she will be much more dominant against the women than Carlsen is against the men, because her competition is not as strong. But here rating WILL still reach Carlsen's given enough rated games played.
        ......
        My problems with the above are the word "consistently" and the phrase "given enough rated games played." No one, even Carlsen, consistently plays at their very best. Mistakes will be made for whatever reason, opponents will ocassionally play brilliantly for whatever reason, and Hou *may* never achieve the escape velocity required to leave her sisters on earth.

So this new woman starts beating all the top women regularly, except she loses to Hou at the same rate that Caruana loses to Carlsen. This new women's rating will eventually reach Caruana's rating.

        If there were an identical woman for every man in the mens' pool, then each identical woman would have the same rating as her identical counterpart in the men's group, again accounting for margin of error. This would happen once the women's group reaches the same size as the men's group. And all without women playing against men. ......
        So.....what you're saying is that if you have a set of chessplayers and you create a second set of chessplayers where the elements of the second set are identical to the elements of the first set, then the two sets would be equal? This may be mathematically correct but I don't follow how something so trivial demonstrates anything useful about men's and women's ratings.

            What Bob G and I are trying to get you to understand is that it all depends on the rating configuration of the two pools of players (Let's say equal numbers of men and women in each group).
            And what you and Bob G. are not understanding is that if the women's pool grows to be the size of the men's pool, AND the women are every bit as good as the men collectively, then the men's pool will continue to have its collection of 2700+ and 2800+ players and the women's pool with have it's own collection of 2700+ and 2800+ players.

            Ask yourself this Bob: WHO ARE THE MEN PLAYING TO GET THEMSELVES A 2700+ OR 2800+ RATING? They are playing AMONGST THEMSELVES!

            They are not playing computer engines and stealing points from that rating pool The men's pool reached its current level or ratings all on its own.

            And if the women are every bit as good as the men, and have the same pool size, they too will have as many 2700+ and 2800+ ratings, all on their own.

            When we agree that women and men are equal at chess ability, there is no "rating configuration" to speak of once the two pools are the same size. Each pool's "rating configuration" is identical, that is part and parcel of the agreement that women are equal to men at chess ability.

            And the size of each pool is large enough to make any actual differences statistically insignificant -- IF INDEED women are equal to men at chess ability.

            So the real goal should be not to have women play higher-rated men, but to grow their pool to be the same size as the men's pool. Then we can compare the two pools and see whether women are in fact every bit as good as men, and it is my belief that they will be.

Then that one rating will go much higher than the average rating of the other 9 elite in the end.
            ........
            Strength only increases your rating when you go outside your pool and win points there, because you are in fact UNDER-RATED, because you've been stuck in your pool.

            Do you not see the contradiction in your statements? If a Carlsen appears among the women, she will increase her rating much higher by beating up on the other elite players in her pool .... strength only increases your rating when you go outside your pool ..... Gotcha!

            Bob A

            I have no personal issue with you. I still say you don't have a bias, you are just not able to see the forest for the trees. Bob G., on the other hand, seems to be in complete disarray. He was cocksure he was going to teach all the "young grasshoppers" the lay of the land, and then whoooops! He found out right off the bat that he didn't have any grasp on it, and so he wasn't going to be teaching us all the "many lessons" we all required because he got schooled. And now he's running away and saying too much aggravation, too much hostilities, when he STARTED that by demeaning language directed towards me.

            The problem with agreeing to disagree is that your view is wrongly held by virtually all the men in chess. And the women don't like it. So it creates disharmony between the genders in chess, and that just hurts the overall goal, which is to bring more girls and women into chess.

            Now, you say it it time to get rid of the women's-only title system. But given these strains between men and women in chess, and the fact that no men are willing to adjust their views and realize fully that women are the equal of men in chess abilities, I have to think that now is not the time, even if these titles should eventually be removed. If it is done now, I think women will leave competitive chess in droves.

              Yeah, when you call the person you are debating with "young grasshopper" which is almost an ethnic slur, but even without the ethnic element, it is demeaning and making yourself to be the Oracle of Wisdom.

              YOU began the "hostilities", dear sir.

              Maybe, given your obvious problems with English grammar and getting the correct statements across, you should just stop writing completely.

                You make it sound like we can dispense with ratings altogether!

                Ratings are used by tournament directors to do PAIRINGS! So that the cream rises to the top. That means ratings reflect chess playing strength.

                And yes, sometimes a player of lower rating beats a player of higher rating, for one or both of 2 reasons:

                1) the rating system in chess is too slow because of the slow aspect of playing chess
                2) the lower rated player did some home schooling and improves his or her chess ability in some meaningful way since the last ratings were done


                Who is out to lunch?

                Not quite, but you're almost there. There are far fewer of them playing competitive chess. And that is the point i've been making in this thread.

                Wilder??? I'm still making the same argument I was making all along. The men here are all wearing blinders, nothing i can do about that.

                I didn't begin the insults. I only gave back as good as I got.

This may be mathematically correct but I don't follow how something so trivial demonstrates anything useful about men's and women's ratings.
                  It demonstrates that if we agree that men and women are equal at chess abilities, and the total pool size of women chess players equals the total pool size of men players, and the pool size in each case is sufficiently large to fully distribute the Elo ratings once some number of games have been played, then as you said, the elements of the first pool are equal in chess strength to the elements of the second pool, with allowance for statistical error introduced by the Elo rating system.

                  Which means that in each pool, whose members we are supposing only play amongst themselves,

                  IF
                  you have 2 men over 2800 and 15 men between 2700 and 2800,
                  THEN
                  you will have 2 women over 2800 and 15 women between 2700 and 2800

                  Any differences will be statistically within the margin of error and not significant. So you might have 1 woman over 2800 and 16 women between 2700 and 2800.

                  Since we are supposing that women as a collective group are every bit as equal at chess ability to men, if follows that growing the size of the women's pool to be the same as the size of the men's pool will allow the top women to achieve 2800 / 2700 ratings WITHOUT REQUIRING them to play the men to get there.

                  And therefore, the effort to get women's ratings up to the same level as men's as a group should be centered on growing the women's pool of players.

                  I'm not saying there is anything wrong with women playing against men, I've already made that clear in a past post.

                  I'm saying it isn't REQUIRED that they do so to get their ratings up to men's ratings.

                  And so the message to women in competitive chess should not be "You must play men to get better!", it should be "Encourage more girls and women to join competitive chess!"

                    Hi Pargat:

                    Pargat:

                    "if the women's pool grows to be the size of the men's pool, AND the women are every bit as good as the men collectively, then the men's pool will continue to have its collection of 2700+ and 2800+ players and the women's pool with have it's own collection of 2700+ and 2800+ players."

                    Of course you are right.

                    IF the elite in the women's pool are of the same RATING (As well as strength) as the elite in the men's pool.

                    The pragmatic issue we face is that in the women's pool, at the moment, the average rating of the elite women is below the average rating of the elite men. You agree to this from all I've read.

                    Now you magically propose a model where the men's pool (I'd prefer calling it now the open pool, to get rid of your inaccurate sexist charge) average elite rating is the same as the elite rating in the women's pool!

                    How did you get there? How did the elite of the women's pool get so high, so as to equal the average elite rating of the Open Pool?

                      Bob A

                      I'll repeat my question to you:

                      HOW DID THE MEN'S POOL GET THERE? HOW DID MEN'S RATINGS GET UP TO 2850?

                      The answer: by playing each other.

                      That's how the women's pool gets there, once it is the same size as the men's pool.

                      If they are every bit as strong in chess abilities as men, which we have agreed on.

                      And yes, i know there isn't a "men's pool' per se, I'm only saying men's pool for arguments sake.

                      You see, Bob, you can't have an Open pool of women and men and then have a Women's pool of only women, and expect those 2 pools to ever be the same size. I hope you at least understand that. So for the sake of our debate, we have to have a men's pool and a women's pool. Capice?

                        Pargat, I highly doubt that Bob G. meant "grasshopper" as a slur. About 45 years ago there was a tv series called Kung Fu about a Shaolin (sp?) monk travelling through 1870s America while trying to reconnect with his American roots. When the protagonist, Kane, was a boy in the monastery, one of his teachers gave him a friendly little nickname, grasshopper. Perhaps Bob made a mistake in assuming you would be familiar with this tv show, but that's it.

                        • Hi Pargat:

                          I'll propose something to try to simplify this investigation.

                          Can we agree on an investigative model, somewhat reflective of reality?: that the 2021 women's pool at the moment has a lower average rating than an open pool of the same number of players. And the average rating of the elite women players is about 200 rating points below that of the elite in the open pool. And for the sake of argument, let's say that, at the moment, there are the same number of players in each pool (arbitrarily.....1000), though in fact the open pool is bigger. For our investigation, I think this fact does not affect the outcome........or do you think it does?

                          We will then try to see how, in both our explanations, the elite women's pool average rating can rise. And whether it can rise 200 points, so as to equal the elite open pool rating.

                          Does this allow us to try to get at where our foundational assumptions are different?

                            Plus, have you stopped to consider that if something as innocuous as a chess rating gets you this pissed off, then maybe you're pursuing the wrong hobby? Don't people usually choose their hobbies based on entertainment/therapeutic values? If you want to engage in something that makes you angry, why not take up politics?

                              Thank you Peter. You are correct. My comment was in reference to the Kung Fu series. Grasshopper was a friendly positive name for the impatient apprentice. I was horrified to read above that Pargat took it as a racial slur. It was certainly never meant as such. It was careless of me to assume Pargat was familiar with the reference.

                              Pargat, please accept my sincere apology.

                                Only one prize per player, whichever is a larger amount of cash. This is a constant problem for organizers and the TD leaning over the crosstables at the end of the event. Usually there's a lower entry fee for juniors/bantams, seniors and women to encourage those (possibly lower-income groups) to play (although these players often face larger travel and hotel expenses). And then they qualify for their own prizes as well as open and class prizes. Studious Juniors could be stronger than their rating and usually win a majority of the open and class prizes. The women and senior prize often goes to the second or third player as a consolation prize for having a good tournament. It's nice to see a variety of people on stage. Most of the prize money goes to the open prizes. An alternative is junior/women/senior non-cash prizes given from sponsors. Sometimes there is a team prize or best game prize but I haven't seen other forms of recognition such as longest game, first win in a rated game, or first overall plus score, or first time moving into a higher rating class, or travelling from the furthest distance.
