Chess Openings's easy interface allows you to quickly learn over 1800 openings. Organized by their ECO
classifications, each opening starts and plays like a normal chess game. Play as black or white, replay or take back
moves - a hint feature shows the best move available from each position and will warn you when playing the wrong piece
or moving to an illegal square.
Chess Openings has over 100 opening variations of the Sicilian Defense, including many of the popular Dragon variations. In addition to 70 variations of the English opening, Opening Pro features many variations of Nimzo-Indian, Roy Lopez, Two Knights Defense, Four Knights Game, Scotch Game, French, Pirc, Caro-Kann, and Catalan, plus many more. Over 1800 openings in total! To view the list of openings in the current ECO, tap the Openings button on the bottom toolbar. To view openings in other ECO ranges, tap the Opening Systems button at the top of that menu.
The openings can be searched by entering any part of the opening name or variation. You can even search starting from any position in the algebraic chess notation of the opening. You can play as White, Black, or both. You can also easily add your own openings to the database.
There are two modes of play - Learn and Explorer. Learn mode forces you to play the selected opening without deviation. Explorer mode lets you play a normal game of chess without any move restrictions, showing you the available openings based on which piece you choose to move.
In Learn mode, after the opening is completed, you can continue play against the CPU, replay the same opening again, or select a different opening. And of course you can always replay moves to explore different alternatives and positions against the CPU.
Chess Openings is an invaluable learning tool that will improve your game.
