Hello.

(I already posted the same question on talkchess.com, got one answer, but looking for more...)

I'm looking for a complex PGN file for testing a PGN parser. Something with complex variations and a variety of test cases.

Anyone with a link to such a test PGN file?

Thanks in advance.

PS: it's for testing the next version of the pgn4web games viewer also used on this site.

I use this game as a quick test for parsers: it has nested comments and variations, as well as NAG codes:
