Chess opening sampler

http://kirill-kryukov.com/chess/tools/opening-sampler/

How many times you thought "Why even in 50 games match do I get double openings with this huge opening book? Should I try an even larger book? Or may be tweak the variety slider? (Thus getting more frequent unbalanced openings too)"

Here is one possible solution. This site provides a random duplicate-free sample from your favorite opening suite. Just select an opening suite, and the number of positions, and click "Sample".

Copy-paste the output into a .pgn file (Ctrl+A, Ctrl+C, etc.) and choose it as an opening database in your tournament GUI. If you'll use each position twice with alternating colors, you need just N/2 positions obviously.

This tool is made and hosted by Kirill Kryukov. All included opening suites are made by their respective authors. Ray Banks and Adam Hair contributed ideas and inspiring discussion.

PGN files can be downloaded here.

Other related tools:
•PGN-Selection by Volker Annuss and Frank Quisinsky. I'm not sure if/where it is still available, but here is a CCC thread about it.
•ChessGUI has similar function, according to Matthias Gemuh (message)

Having some problems here. I tried duplicating 200 move opening using swcr fq--v4.1 pgn

selected to limit to 200 moves generated output and copied.

Here I ran into trouble I created a blank textfile (database) but when I try to paste into the open text fdile nothing happens

What am I doing wrong ? I have a 200 moves.pgn file with no gamnes in it but when I pasted into it nothing happens

Not sure what exactly you're trying to do.
Are you trying to create a ChessGUI opening book from a PGN file?

No trying to create test suite for chessbase gui 14. Is that sampler only for chessgui ?

Not sure.
I've never bothered with test suites, so I'm no help with this one.

Ok I figured it out. It will work with chessbase

The trick is save the output with a file name like mytestsuite25.pgn or name# of positions.pgn

cntrl a on output
cntrl c on output

You can use a text editor like notepad to save as, with save as type = all files

open up notepad
cntrl V to paste data into notepad
save as (under file)
save as type = all files
enter name = mytestsuite25.pgn or whatever you choose.pgn
save

this will create a file chessbase can use
