A quick thank you, James.

PS. How do I disable book and logging?

Book is not enabled by default (if you are using the .bat file included in the zip just remove the -book=.... command line argument)

Logging - I'm not sure that you can. I actually hadn't considered that someone might not want logging on. I'll see if there is already some way to disable log4j using an argument, and if not push a small patch to give that option. I'll follow up on this thread.

I'm not particularly keen on disabling logging, I was just a bit surprised to find a 130 MB log file in the chess4j folder when I installed 3.4.

Any idea of this new version's strength?

I just posted 3.4.1 to http://www.jamesswafford.com/chess4j/ . I've gone through the logging statements to be sure they are at the correct level (info, debug, warn, error) and changed the default logging level to INFO for the release. Other than that it's the same.

It should be marginally stronger than 3.2 which was at 1961 I believe on the CCRL list.
