To have any statistical relevance the names of the players must be spelt consistently. For instance, Gary Kasparov, Garry Kasparov and G. Kasparov would be treated as three different players.

ChessBase allows you to automatically correct spelling variations of player names in the player index.

 

Load the player index of a database. Click on the heading „Player“ in the list.

 

The function can be found in the menu Players - Improve Playernames.

 

 

After completion the program tells you what it has changed in a small information box.
