What happens if a player restricts all his games to under 13OO [for example] will his rating continue to go up as long as he keeps winning or will he have to take on the higher [than himself] rated players?
Yeah yeah I know the rating system has been explained a few times but this hasn't been made clear anywhere I can see.

Thanking you in anticipation of a swift answer.🙂

Your rating would climb until you reach the point where the difference in yours and your opponent's rating is such that you no longer gain points for winning. Against opponents rated 1200 you could theoretically reach a rating of about 1797.

I can't take the credit for actually being able to work this out.

I'm not good at the statistical science but I would say they are pretty accurate if you randomly accept opponents.
Most heavy players have spraed of about 130 points higher and lower than their rating. Certainly I consider myself a 1250 player, I have been to 1380 twice but never beyond, but I've rarely fallen below 1170.
In over 2000 games this is highlights how accurate the system is.

Totally agree.

Played over 1300 games, max rating 1385, minimum 1129.
Reckon I am probably nearer 1280/1300 but go through bad spells :'( every now and then.

I find that I lose rating points by playing people with a lower rating rather than gain them.

It doesn't matter what flavour it is because you can't learn from cake and eat it too.

Ok, another question,
if a 12OO player was to restriict his opponents to over 18OO only and he kept losing would he end up with a lower rating than a 12OO player who restricted his games to players under 12OO but kept winning.

Maybe I should've put this in the riddle-me section.

Again not a whiz with the maths, but I have a feeling the answer is yes, because you stop gaining/losing points once the gap between you is about 400 points (I think). I know someone has suggested it's more like 600, but that doesn't accord with my memory.

If you started from scratch, a provisional player losing to people ranked 1800 and over would actually have a rating of at least 1400 (I know for sure this is what happens with provisionals). After 20 games, they'd start losing points but I think they wouldn't lose any more somewhere around 1400. It might be a little lower than that.

A provisional player who beats people under 1200 will have a maximum rating of 1600. After 20 games I think they can keep rising to somewhere around 1600, although it might be slightly higher.

This is (a) all very theoretical and (b) kind of a painful way to run your chess life.

I wasn't planning on using the information at all, I just wondered how accurate the numbers really were.
Thanks.🙂
