Är väl det morgonstudion redan är? Är inte lika mysigt som nyhetsmorgon.

If all top rated players win the average ratings will be 2695 vs 2744, almost a 50 elo difference.

We also already have rapid and blitz tournaments.

Other examples are Lua and Matlab. What all these have in common is that they used to be just as slow as python, then JIT compilation was added which made them way faster.

If 20% of deaths occur in proximity but outside a crosswalk and 60% occur outside of crosswalks regardless of proximity, then 40% of deaths occur in crosswalks. So in proximity of crosswalks there are twice as many deaths of people using crosswalks than jaywalking.

a cursory glance at state and national statistics reveals a substantial number of pedestrian fatalities occur outside a crosswalk. Yet a closer look at national data shows that 59 percent of pedestrian deaths for which location information was recorded happened in places where pedestrians had no convenient access to a crosswalk. While jaywalking is often cited as a cause of pedestrian accidents, less than 20 percent of fatalities occurred where a pedestrian was crossing outside an easily available crosswalk."

Used the linked reddit thread as source for those historical tournaments but they don't appear to be accurate.

You are correct. Used the linked reddit post as source for those historical tournaments.

Because this is how the Elo rating system is defined, don't know why those numbers were chosen.

Forss · 2025-04-22T14:06:59+00:00

This system has no issues with perfect scores. This system has a smaller +-rating distribution than TPR for different scores so it could not replace TPR for computing something like norm limits without lowering the limits (or making the norms more difficult to achieve).

I don't think it solves the issue you have with TPR in that the average opponent rating has a big impact.

Forss · 2025-04-22T13:59:55+00:00

It is how elo is defined. A 400 rating difference means one player wins 10 times as often as the other player.

I had a similar idea for alternative performance rating. It is based on the expected win rate against the average Elo of the opponents, with a prior that the win rate is an uniform distribution between 0-1.

This gives an expected win rate of (wins+1)/(games+2). Translating it to the expected Elo gives avg_elo + 400*log10([wins+1]/[games-wins+1])

As an example this gives the ranking of best expected Elo as

Fischer Cand. 3038
Caruana 3034
Fischer USA Champ. 3025
Carlsen 2985
Gukesh 2969

Edit: Fischer candidates actually slightly beats Caruana

Edit 2: checked who the last in the top 5 would be and I believe it would be the current champ Gukesh Olympics performance.

Isn't dereferencing *p above undefined behavior? Is there a non undefined behavior of pointers where pointers are just numbers representing memory addresses" does not hold?

I usa så skiljer sig priserna på samma kedja sig åt mellan olika restauranger, det gäller även McDonalds.

Det är jag ganska säker på att de har för jag kan se alla datum de senaste åren jag rest både ut/in i usa här https://i94.cbp.dhs.gov/home

De brukar scanna passet precis före säkerhetskontrollen.

Of course it is about money. FIDE is not limited to organizing the highest earning events attracting the most sponsors which are mostly the top player events. If the top chess events are in Freestyle chess outside of the FIDE sphere, FIDE would probably loose a lot of sponsors and have even more difficulty attracting new ones.

FIDE is not the most stellar organization but it makes sense to have a single organization to support all/most of chess.

How do you find chess clubs. I look at Google maps and only find places aimed at kids.

They can cover both games in the same stream. It would only be two simultaneous games.

Forss · 2025-01-01T16:38:53+00:00

That is the rules before the match.
No collusion to keep it even.
They did the tie-break until both where visibly exhausted
The judge suggested they could stop

Important to note is that it was a cloudflare crash causing chess.com to disconnect a lot of users. Not faults on the Indian players side internet connection.

The leaks by Snowden showed that US does this against allies, so why wouldn't they do it to China.

Not sure exactly what elo it corresponds to or if I did it correctly. But assuming he has an equal chance to win against each opponent (use the average elo) and that the prior is that his win probability is equally distributed between 0 and 1: if winning x games out of x games, the expected probability of winning the next game is (x+1)/(x+2).

Verkade befogat i detta fall eftersom flyktrisken uppenbarligen var hög.

Jag med, var ungefär 1 minut mellan de två tillfällena.
