Strong club players may reach 2000 points, International Masters are usually 2300 to 2500, Grandmasters up to 2700, with a very small number of players exceeding event that( Garry Kasparov is the only player in history to exceed 2800). Twice a year the world chess federation issues an Elo rating list with ratings for tens of thousands of players.

3.5.2 ECO classification
The abbreviation ECO stands for“ E ncy clo pe dia o f C he s s O pe nings”, a standard reference for openings that is published by the Chess Informant. Individual variations of an opening are denoted by abbreviations like“ C43”( Petroff with 3. d4) or“ D89”( Grunfeld Indian Exchange – main line). The system has become universally accepted and is also used by ChessBase.
In the search mask you can specify a range of openings( and combine this with players, length, result, etc.). Click on the ECO checkbox and enter ECO codes, e. g.
“ C43” and“ C45” for all games from C43 to C45“ C” and“ C45” for all games from C00 to C45“ C45” and nothing for all games from C45
The number behind the slash in the code(“/ 99”) denotes the subvariations. The ECO code is embedded in all games supplied by ChessBase and displayed in the games list. If a set of game you get from somewhere else does not contain or has incorrect ECO codes you can have them inserted by ChessBase.
