A CTG chess openings database based on the IECG correspondence chess games, as available from

http://iecg.org/garchive.htm#Downloads

and selected by the following criteria:

--> game length 12...80 moves
--> at least one player 2100+ rated
--> no games which contain "forfeit" or "time"

This resulted in a total of 33,526 games, from which a CTG book tree was built:

IECG-2100_3rdEd.CTG

contains 1,183,912 positions and the max. variation length is 30 full moves. For engine games with shorter book variations, you can limit their length in the book options of Fritz if desired.

Just like the IECG games, this is provided free of charge (incl. PGN+CBV).

(The first and unfortunately, also the second edition suffered from some data problems.)
