Unlike most other systems, lower numbers indicate better performance Harkness —6. The Harkness System was invented by Kenneth Harkness , who published it in It was used by the USCF from to and by some other organizations.

When players compete in a tournament, the average rating of their competition is calculated. This is Clarke and first published in Points are scored for every game played in a registered competition generally, English congresses, local and county leagues, and other team events.

A player's grade is calculated by taking the opponent's grade and adding 50 points for a win, subtracting 50 points for a loss, and taking the opponent's grade as it stands for a draw.

For grading purposes, it is assumed that the opponent's grade is never more than 40 points above or below one's own.

The ECF grades approximately , games a year. The grading season runs from 1 June to 31 May. An ECF grade can be approximated to an Elo rating by multiplying by 7.

The Elo system was invented by Arpad Elo and is the most common rating system. It is used by FIDE and other organizations. Elo once stated that the process of rating players was in any case rather approximate; he compared it to "the measurement of the position of a cork bobbing up and down on the surface of agitated water with a yard stick tied to a rope and which is swaying in the wind".

FIDE classifies tournaments into categories according to the average rating of the players. Each category is 25 rating points wide. Category 1 is for an average rating of to , category 2 is to , etc.

Quickly and easily record the implementation of a corrective action. There's nothing easier. Call up the corrective action on your tablet and record the result by taking a photo.

What has changed since the last inspection? The tablet displays the results of the last inspections. You can apply the last result to the current inspection with a single tap.

Need it quicker? Then use QR codes. These can be read easily by your tablet and integrated in inspections. Evaluate what is important to you. Are you only interested in the inspection results?

Then only look at these. No frills. Do you need the results displayed graphically? Using Q-Chess you can create reports with tables, images and charts e.

Are you interested in trends and changes? Then you'll find exactly what you're looking for under quality analysis: inspection results and key metrics on the time axis as a line or bar chart.

Do you want more details? Correlate the data or evaluate it using separate functions. Integration in existing IT systems Q-Chess is not an island and double data storage is not a good idea.

Do you already have an ERP system? If you need to use these in inspections then we can set up an interface and define which data should be imported and when.

Do you have a sophisticated reporting system? Then you should integrate the data recorded in Q-Chess with this. Let's stick with the example of SAP.

Q-Chess provides web services that you can call up from SAP to use the required data. But SAP is just one example. Q-Chess supports many standards.

Ask us and we'll integrate Q-Chess into your IT environment. The mobile client is designed as an app for all types of smartphones and tablets.

This feels insecure. Is the app safe? For instance when I click on the forum of lichess the app opens and cannot read the forum.

This occurs when I click on all url's of lichess. So I can't post this problem on the forum. That's why I post it here. The discussions forum of lichess is closed.

I think they do not like the discussion that the app is not safe anymore. The app is not safe.
