A discussion about K-factors

In this post let's discuss the pros and cons of K-factors for adults. Now a days kids can become so strong because they play without pressure of K factor thing but what about adults like me and other adults? We have only first 40 games which gives us K-40 rest goes down and down on the other han kids have more chances due to under 18 thing. I totally disagree with FIDE rules regarding K factors because I think it gives more opportunity to only kids but does not help aduts like us. Kids have no responsibilities but on the other hand adults like us have more challange. 

In case of me I have only 12 games left for K-40 factor then this factor goes down. If we think in realistic sense then it will become so much tough for me to become GM. Because we all know becoming a Grandmaster requires so much work and money and coaches and so on but also elo sucks. It will take more than 10+ events for a player like me to learn and maintain 2000 elo strength then real battle will start. Yes I believe I can get 2000 elo once events will start but this is just a milestone and then getting title will become more and more tough.  Even if I do my best this elo may affect my work. I saw so many strong players who started late and never became  2000+ due to this K systems. 

About me? I work well with my teammates so my game is def. improving and I do know that chess game level matters not elo but in order to get students and money we need elo also. I left everything for chess because my mind can't think of other things now a days apart from chess.  Even though I am able to understand computers faster than chess but still I chose chess because I love this game so I work on my game strength 

I wanna know your opinions guys.  Like some of the adults who are in chessmood to become titled players. How you handle this rating k factors things and how you believe that you will cross 2200+ even with less k-factors. Share your strategies also. 

Again, I wanna say I know game matters not elo but still i wanna know how you guys handle less k-40 thing.

Definitely the topic I have been thinking a lot lately. I used to play chess long time ago, but didn't have FIDE rating but only national rating of around 2150.

Few months ago I played my first official  OTB tournament and and since my oponents were not very strong I ended up with 1800 starting ELO rating, even though I won the tournament easily. 

So now I have only about 20 games left with K=40.

I registered for two upcomming tournaments but I will play  only the one whih has >1700 ELO limit as for the second tournament my rating doesn't qualify me for the main group.

Playing against much weaker oponents with K-40 is risky as when you win you gain little and when you lose you lose a lot.

Well good luck in upcoming event. I hope you will reach 2000+ in next event with K-40. I only played 3 rated events and have 1465 elo now but for the next year my plan is to play 10 event with prep. and gain 600 elo points to reach 2000+

I got my first rating when I was 17, before all this K-40 thing for U18, which I agree is discriminating elo-wise older players aiming for FM like myself.

Been playing with K-20 as far as I remember and got max to 2260 in 2017. So almost made to FM, just needed couple good tournaments. But maintaining this rating was super hard, especially when having a job, so I dropped to around 2150 level again. Current rating 2172.

Imo reaching 2000 is much much easier than maintaining 2200. You have to work on your chess constantly, cause even one bad/unlucky game against lower rated player can really demoralize. You have to be fierce, merciless and with killer instinct (which I lack :)) to be able to reach 2300 it seems

still nice elo @Paulius_Juknis . But yeah this elo system sucks and stops so many players to gain title like you need FM

The rating system is a bit of a mess, as not only does it not take account of big improvements in adults, but it also keeps high rated people high rated even when they no longer deserve to be (and also means rating inflation as lower rated players gain points based on rating difference). It gets worse at 2300 when K becomes 10.

They should adopt a Glicko style system where rating can adjust more if you don't play for a long while as the uncertainty of your true strength increases. The problem is though that it can encourage sand-bagging and entrance of tournaments much lower than your rating (so would need some way to prevent once strong people entering tournaments much below their grade).

As for take a long while to get there, yes it might have a reputation effect if you're looking to teach, get a title or on a national team, however, the flip side is you can enter graded tournaments and be much stronger than most of the field. Also if you're a 2400 rated 2000, it could be quite scary for your opponents.

Another rating problem is that the pool of players. In (most) local leagues there are only a couple of players above 2200, so as you start to get 1900, 2000 (and assuming that's most of your games) it gets hard to put on rating points as you're often against lower rated players and a few draws keep you down.

Yes, that's also a big issue.  I started living in Captial of India now so it will be easier for me to play against strong players but now due to fungus and covid stuff there are no local events. This current FIDE rating system affects so much adults who are working to become titled player.

Just a difference between K20 and K10: with the former, it is possible to obtain +18.4 if you happen to be on form against +400 opposition; with K10, the same thing is not possible unless you are constantly playing Carlsen. Consequently, if 1 win nets 8 elo on K10 then it is already perceived as some sort of super achievement.

Can someone tell me what a K factor is? I have no clue I have not been involved OTB in many years,

Your new rating = (pregame rating) + K * (w - E)

Where K is a constant, w is the result (1, 0.5 or 0) and E is the expected result (based on the difference of ratings).

It's therefore the maximum number of rating points one game can earn or lose you.

In the glicko system, K isn't constant and changes based on 'rd' which the larger it is (with a max like 350) the less often you are playing, and it becomes asymptotic towards 0 the more often you play. Thus if you're playing every few minutes over a long period your rd and thus K will be very small (it's likely your rating is stable) and will be floored at some value (e.g. 16) so some points still change hands. If you go away for a few months, it's possible that you've improved or gotten rusty, rd, and thus K will rise to allow your rating to adjust to your current level.

It also means that points are not conserved since your opponent may win or lose more/less points than you. This means it can potentially be inflationary or deflationary over long periods of time.
