The latest version of 5 is very similar strength to GNU Chess 4 I believe.

5.02 had some very suspect weightings in the evaluation functions,
making it place way too much emphasis on central control, against most
humans this wasn't such a big issue but it would struggle badly against
other machines.

The style of play due to overly high central control was actually quite
interesting, I can imagine some people preferring it, especially if it
normally beats you anyway.

I think this may become an option in 5.08....
