Elite Chess Database vs chess.ceo

This app is for viewing, studying, analysing chess game databases and solving puzzles. It comes with some databases: - Elite database: chess games of human very high ranks, from 2400 Elo. All games are checked, and verified to eliminate errors and redundancies. Player names are checked, standardised too - Annotated games: almost all interesting games with annotations on the Internet. We believe it is the largest collection of annotated games so far - Puzzles with mates from 1 to 9: suitable for all players’ levels, for enjoying as well as for practising. Users can try to solve them and then ask the app to verify their solutions Users could analyse any game for computing information, best moves and for finding blunders. The total of all games and puzzles is huge. A typical human can’t watch and/or solve them all in their whole lives.
