We just release our new tactics trainer 1 2 chess! at https://12chess.com.

Training tactics every day is essential to improve your chess playing strength. 1 2 chess! allows you to log in with Facebook and track your progress, solving tactics suitable to your current level.

1 2 chess! includes thousands of original chess tactics from real tournament games played in recent years. The tactics database grows constantly adding new tactics from games played last week.

It also publishes a new chess tactic every hour in the Facebook page and the Twitter account @onetwochess.

This is a project made with our chess technology developed in the last years… by chess lovers, for chess lovers.

Now you can link from external websites to a specific database query in the Mobialia Chess web app with Urls like:

• https://chess.mobialia.com/?db_query=Carlsen+Karjakin
• https://chess.mobialia.com/?db_query=Deep+Blue

You must pass the “?db_query=” parameter with a Url encoded value. Multiple values must be separated by “+”. This encoding can be done with a online Url encoder like http://www.url-encode-decode.com/.

The link opens the Mobialia chess web app in the database game list screen. The passed value is searched in the player names, events, sites and dates.

One of the most important chess tools for a regular chess player is a chess database. Searching for historical games or certain positions allows you to improve your chess knowledge and to do a better analysis of your games. In version 5.3, we added this feature to both the Android and the web app. The database consists of millions of games updated regularly from Mark Crowther’s The Week in Chess page.

From the sidebar in the main screen you can access the “Database” screen with a form to search in player names, events, sites and dates:

And from the board screens you can search the current position with “⋮ -> Search Position in DB”. Searching for a position shows a statistics screen with the move played, the number of database games in which this move was played, and the percentages for white victory, draw and black victory represented with bars:

Analysis mode was one of the most requested features in Mobialia Chess, and finally it will be available in Mobialia Chess 5.2. It works in the Android app and also in the web app…. with the chess engine is running in the browser! http://chess.mobialia.com

Analysis in offline games

Playing offline this new feature replaces the old “Hint” menu option.

Analysis in online games

Playing online it will be only available while observing or examining a game. It does not allow to analyze a game while playing because it could be used for cheating.

When a played game is finished, you can examine it with the “Examine” menu option and then start the analysis. You can also browse your played games in the “History” section to analyze them.

Openings names and ECO codes

The analysis window also shows the opening name and the ECO code (https://en.wikipedia.org/wiki/Encyclopaedia_of_Chess_Openings). The opening names are available in 5 languages and they also include the name of the variants.

The openings database was very big for being embedded with the app, so it is done querying an online service in the Mobialia servers.

Updated engine

This new version includes the last Carballo Chess Engine 1.5 with a great strength increase over the previous version, we worked a lot the last months in our opensource chess engine: (https://github.com/albertoruibal/carballo/). In the analysis mode the engine works always at full strength. Playing against the engine, we keep the ELO levels 500-2100, but probably now it is a bit stronger.

Material Design is coming with Android 5, and we implemented some of their principles in our Gas Stations app.

We started redesigning a new app logo from scratch and then we changed the app colors, redesigning a new sidebar and then applying “ripples”, elevation shadows, etc.

Two weeks working in the new design that we are are complementing with other improvements in the price update and route calculation processes.

We hope you will like it:

We spent the last weeks working on Mobialia Chess, porting changes from Android to HTML5 (at http://chess.mobialia.com). It also works now for Internet Explorer 10, given that Microsoft added WebGL support, and will most likely work on IOS8 as well, as long as Apple is doing the same for Safari Mobile.

Thus, we released Mobialia Chess 5.0.4 at once for Android and web!

Some features such as Themes, board setup, PGN and speech are available only for the Android version, but all the other options are equally functional in both platforms. Both apps share now the same changelog, and we will do our best to keep the development in sync in the future.

The migration of Mobialia Chess from Android to HTML5 was possible using our open source library GWT_Android_Emu, available at GitHub.

We release today Mobialia Chess version 5 for Android. It is the result of many months of work improving the app. Changelog:

• New standard actionbar with new icons and new menus
• New sidebar in online play to access all the sections: you can show it sliding in the screen from left to right or pressing the top left icon
• New Observe section listing current games in the chess server
• We moved the old observe options to the new Observe screen: now you can “follow” the best games in each category
• New Messages section to read and send messages in the chess server
• Support for playing on the ICC Chess Server as Guest (requires two more app permissions to generate the device ID)
• New Events section when connecting to ICC
• New History screen replacing the old “Examine last game” option, now you can examine or send by email all your played games

As this version brings great changes, we provide links to download the old 4.3.2 version for users who prefer it (or users experiencing some kind of problem with the new version, but please send us an email explaining your problem). We also offer the download of the last version from the Mobialia Chess page because we found many pages offering versions of Mobialia Chess that are viruses:
