As someone that has invested into chessbase and the chessbase products for years. There has never been a trial version as far as i know.
Their Reader 2017 program is free and has some of the features and limited DB size. It's also pretty old at this point, so I don't know how similar it is to the newest version.
So, I was looking into buying chessbase, as I recently started accumulating a bunch of OTB notation papers, and wanted it filed in a neat program on a laptop I can take to future tournaments, but I don't wanna waste a ton of cash on the program, unless i've tried it beforehand.
Are there really no trial version?
Just for reference, I'm not looking for other databases I can put my stuff in, just Chessbase for now
EDIT: For anybody looking for the same. Chessbase does not have a trial version. Good luck
