200, yes. In Ants case it's a real shame they didn't find out before the
tournement. ( that was a 200 or more difference )

For amateurs I disagree. Improving your program should be more important than
playing it safe. If I "feel" something is an improvement ( I like the playing
style, doesn't score too much worse on test positions ) I will play with it in a
tournement. If I get killed, well, shit happens.

XiniX is capable of the basic WB functions. But for full support I need more
time. And time is the thing I don't have a lot. Full WB support is not an urgent

Diep is stronger than XiniX. Don't know about the strength of Nimzo. It could be
that Diep likes the playing style of Nimzo. I know it doesn't like XiniX'
playing style. XiniX doesn't like Tao, ANT doesn't like XiniX. Kind of

That means that in matches strange things can happen.
