You're wanting this to run engine v engine testing?

[jmartus]

yes 1 vs 1 too probaly like 200 game matches or more.

The only Arena books I kept because they were best in my eyes were the Xmas2640.abk (which is quite small), plus the Harry Schnapp books.
However, it's been a while since I used Arena, so some other good books might have been released in recent years.

Can you or someone link me to a good pgn file of games I can use?

There is a subforum in the Chess2U forum that might help.

You can try Perfect 2012 by Sedat Canbaz, are made to test engines.
Small, not bad.

If you want some real diversity, I would suggest you use my home made opening set:

The file may be too big for Arena, so you can just keep the first 200 lines, or however many you need. The opening positions are already randomized in the file, so loading sequentially introduces no biais.

It's pretty simple to create an Arena book from PGN files. Why not use the Noomen test suites to create a book for engine testing?

Another rather small alternative is the Balanced-14.abk:

Almost 220,000 moves from quality games, compiled with the aim of a bigger diversity as usual. Max. length 14 full moves, but the average will be smaller.
