Refreshing opening suites

From time to time it's handy (and with extensive use maybe even necessary) to refresh the opening suite(s) one is using for eng-eng testing. I have written a small util that just does that. It rests on the assumption that grandmasters above 2600 or 2700 elo don't make big mistakes in the first 10 moves. Another advantage is that the openings are based on real games. The util is part of PGN-Annotator version 1.2 2 x 10 opening suites are already created in the sub-folders gm-2600 and gm-2700.

Examples made from gm-2600.pgn

From the web-page -
Create opening sets for engine-engine testing. From a good PGN create flexible opening sets. Included in the Annotator-Basic version (download below) are 2 PGN's (gm-2600.pgn and gm-2700.pgn) with only games between 2600 and 2700 elo rated grandmasters. Press [F11], select the PGN and type the number of moves and a corresponding PGN opening set will be created. In the gm-2600 and gm-2700 folder are the 2-moves.pgn .... 10-moves.pgn already created.
