Play chess online at FICS or ICC, play the Pulsar Chess Engine on or offline with chess and variants like Chess960 with levels, and use the Openings Explorer with an opening tree book based on 345,000 over the board games and analysis which also works offline. There is In-App help. For online play, if no account, use the Connect as Guest button to play unrated. FICS accounts are life time free accounts. Diamond Chess supports Dark Mode and has no ads.

Diamond Chess seeks to be a complete chess app, not just online play. All games are logged that are played, and there is the ability to load and examine them with engine analysis to study and learn from last games. The Watch Game Board option watches a high rated game which is also designed as a way to improve in chess by watching. On FICS the Find a Game Board Option has a Training tab for endgame and puzzle studies that both guests and members can use.

The Explorer Tab which works offline or online with certain restrictions while playing, offers an Opening Tree based on 345K over the board games were both players are rated over 2300. The move table view can be toggled to show analysis and PGN games including the players log file can be loaded. The chess opening name is also given after a few moves are made. There are 10 PGN game collections available in app that include Morphy 1858, Fischer’s best games, a Capablanca and Kasparov collection, and a range of game collections from classical too modern to be viewed with the opening book and analysis, on and offline.

There is an on board multi level chess program that plays chess, chess960, a form of shuffle chess, and a few variants such as Crazyhouse, Atomic Chess and Loser's Chess. The engine option on the connect tab is available on and off line. On ICC there is an option for members to play 50 Chess Videos in app which trials can access too.

As a guest by moving between ICC and FICS users can experience two different playing pools. Guests on FICS can observe high rated games on FICS, and view theirs or other players recent games. On ICC guests can use the Play Bots option to play tactical and endgame bots, play other players, view games that are finished from important relays with Broadcast option, and view their recent games by the open log file option.

The Diamond Chess board features engine analysis with one click when observing a chess game or examining one. Diamond also has a load PGN option and logs all played games to PGN. Multiple games can be up at once and users click the next or previous buttons to move between them.

Diamond Chess supports both chess and the server's variants such as Crazyhouse, Losers, Atomic Chess, Giveaway or Suicide Chess.

Diamond has an accessible board to use with Voice Over for the visually impaired. On the settings tab in the Voice Over section, there is Voice Over help available with commands that can be used from the console.

Members can join channels and chat in the Diamond Chess console or if the users is familiar with them issue server commands.

ICC, Internet Chess Club, has free levels and free guest access. FICS, Free Internet Chess Server, is entirely free.

Very complete Fics/ICC interface.

Unlike most mobile FICS/ICC interfaces this has a console, which is key to exploiting the servers full features. Necessary for any serious FICS interface, in my opinion. A list of sought games would be nice and when I set seeks ro ‘1’ I don’t see them in the console for some reason? Otherwise very full featured app for serious online chess players!

Developer Response ,

Thanks for your review. The seeks are going to a seek graph. You can get to it by going to the board's option button at top then "Find a game"

Too complex , definitely not user-friendly, and poor support, if any

First of all you have to meet all the help files in order to get a game rather than having simple commands as part of the interface to obtain a game. I’ve tried four times to get a game as a guest and each time when someone responded it was immediately aborted. The server window gave two different sources to contact for help via a tell. This was at about 11 AM central time; So there should’ve been someone “on duty”
Both help sources were not available, to answer my question why were my games aborted. And when I did put it in the command to find out how many people were seeking games, there were only three. Clearly this is not a popular interface...
Don’t bother with this interface unless you have a lot of time to figure it out... moreover there doesn’t seem to be help responders available... not sure if I can give this app zero stars so I just give it one

Developer Response ,

Board has two menu buttons and on Options there is Find a game which has a seek graph and a graphical seek a game view. Sorry you had a bad experience. I'd encourage you to try it again and also my other app, lantern chess interface to icc, which people can see if they go to my other apps on app store page, also totally failed you, as you said and you could not move the pieces. I'd encourage you to try that again.

Takes some getting used to...

Takes some getting used to, but once you get it configured it is not bad.

Under settings set queen promote to off or you will regret it, ought to be the default, no idea what they were thinking. while there maybe set slide pieces to on.

This app has some bugs so don’t be surprised.
