I think they certainly have increased their ELO, but more importantly, their overall chess strength. ELO is only a rating relative to others in the pool so it may tend to go up more slowly if everyone in the pool gets better, which they have collectively. First, you need to take an average of the top players, rather than look at just two incredibly special ...

The question is apparently based on a misunderstanding of how ELO ratings work. There is absolutely no mechanism by which the overall increase in players' strength would lead to increase in their ELO. The actual value of the ELO rating bears no meaning; nor does the comparison of ELO at distant times. The only thing that has direct relevance is the ...

The Elo rating system is a rating system for two-person, zero-sum games based on the assumption that performance is normally distributed. That is, a player's performance is expected to follow a normal distribution. For FIDE the mean = the player's rating and standard deviation = 2000/7 = 285.7. It was developed by Arpad Elo and first implemented by the ...

A typical way to do it is to treat puzzles the same as players and rate them based on whether they "win/lose" and the rating of the "opponent" ChessTempo has a nice explanation here copied below: The rating system is inspired by an idea implemented at the Chess Tactics Server. CTS treats both problem solvers and the problems as opponents with their ...

To make GM, a 2500 FIDE rating is needed, among other thing. But there is not a separate "Elo rating" which is also needed. Elo rating is a generic term for any rating system based on the work of Arpad Elo. It's also often used as shorthand for FIDE rating. If someone says their rating is 2500 Elo, that normally means 2500 FIDE.

If those engines have a 3600 Elo, shouldn't top players have profited from it to leave Kasparov's 2851 score in 1999 far away? No. The main effect of engines and also the internet has been to democratise chess. The top players have always had access to top level evaluation and knowledge. For lower level players that kind of knowledge, analysis, position ...

"PhishMaster's Complete Guide To Improvement": What to study, and how. Every player has times where they "plateau", and have trouble moving on, but they usually get past it eventually if they are continuing to study. Sometimes, it is a matter of patience. Here is a set of comprehensive answers to questions I previously gave in various chunks, that are now ...

From your context, there is no difference between the two. "Elo" (From Arpad Elo, a professor at Marquette University and president of one of the two organizations that merged to form the US Chess Federation back in 1939 -- IIRC he chaired the meeting that resulted in the merger) when used by in the context of FIDE titles typically refers to the FIDE rating ...

A few things: 1) Ratings overall tend to rise due to inflation of more players entering the pool, rather than the average playing strength of players increasing. If everyone becomes better by some factor due to engines, why would top players' ratings increase? They're now playing opponents who have also gotten stronger by roughly the same amount. 2) ...

The way FIDE rating (and rating change) is calculated is described in FIDE Rating Regulations effective from 1 July 2017. For an already rated player the calculations for working out the rating change are given in section 8.5. From here it can be seen that how fast a rating changes for a given performance depende on the "k factor". This is defined in 8.56: ...

Are there any sort of equations for how much of a handicap one should receive to make a game between two players with differing Elo ratings as balanced as possible? The short answer is "No", there is no scientific equation, but it doesn't stop people from trying. For instance, our club runs an annual handicap tournament in which it tries to produce a ...

It really depends on where you live, and who is there. Some can be very good. For years, in Boston, well Cambridge really, there was a player, who was a regular at the "Square", Harvard Square to be precise. It is right across from the famed university, and IMs have been known to congregate there at times. Murray Turnbull was about 2350 USCF when I would ...

Let's pick a random tournament I found individual board results for - the 2017 US Amateur Team West. The maximum average rating for this tournament was 2200, rather than 2000, but it should still be instructive. For this tournament, the average ratings by board (not including unrated players) were: Board 1: mean 1874.24, median 1949, max 2592, min 1026 ...
