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.
