Chess Openings Explorer

Chess Openings Explorer


Database of all 2.3M standard games played in 2012 on The Free Internet Chess Server (http://www.freechess.org/)
Sorted by opening moves, white/black win/draw statistics included
Requires 700MB available space on SD card for the uncompressed games database, additionally to the app itself.

Please send your feedback, it will be appreciated

STORAGE issue. Recently I have added code to work around the KitKat sdcard write restrictions. The uncompressed database is now located at "external storage\data\Android\name.duzenko.chessopeningexplorer"
The problem is some vendors, like Samsung, link external storage to internal phone memory. For Samsung devices only the app will try to use "/storage/extSdCard/Android/data/" so that precious internal memory is not used. If you have a non-Samsung device and want the database on your sd card and not in internal mmeory please contact me via email and I will try to add your vendor to the exception list.
BTW Previously the database was kept in "extsdcard\Chess Opening Explorer". Old files did not get deleted automatically so you should probably do that manually to free the 700 MB of space that the database takes up.

Fantastic Great app. But recently the percentages for white win draw and black win keeps changing. If I scroll the screen up down, the percentage changes... Can help fix this?

Superb I just hid the action bar in latest update and now settings button doesn't work. Cant get action bar back! Also, O-O-O+ not working in the 1. e4 d5 2. exd5 Qxd5 3. d4 e5 4. dxe5 Qxd1+ 5. Kxd1 Nc6 general area. Still, it's super handy. Great work guys!
