Not to turn this into yet another thread about BB, but in the context of WC, I have a few BB management questions for the wc experts out there:
1) Is it possible in GC to do a wc where BB ends up under 60? I'm just starting my second wc attempt, playing England, and in 1609 I've got a BB of 66. I've attempted to keep my BB down, but I'm finding it very difficult not to go out wipe out those snot-nosed Portugese!

But of course, if I start an offensive war and take 'em out, I'll rack up mountains of BB
2) I've figured out that I've under utilized diplo-annexing. I did use it as much as possible while England was still Catholic, then discovered I could no longer DA my (many) Catholic vassals. So I released all my vassals, and then ended up force annexing Ireland, of course picking up a wopping 6BB pts for Ulster (not at all a good bargain - but it had to be done!).
Then I noticed in a recent war w/ Spain that I can in fact force convert (I was under the impression that only Counter-reform Catholics could do that). So, is it a practical strategy to get into a war (possibly even an offensive war, if necessary), then force convert Catholic nations, and then in that war or a follow on war force vassalize them, thus re-opening the option to eventually DA them? If I can do this to Catholic nations, can I also do it to Muslim nations?
2a) If I force vassalize a nation, does that mean that that nation will in turn release its own vassals?
3) As I understand it, after you've taken all your cores, the best you can possibly do to minimize BB is 1 BB/province (taken from non-pagan nations, of course). As such, unless I've missed something, defensive wars are the only alternative to diplo annexation, and I've tried to get the most that I can out of the defensive wars that come along, however, once I get a powerful econonomic engine running, and I start to rack up tech levels, other nations soon become afraid of attacking me, and I see few (if any) defensive wars come along.
In my current game playing England, I am playing around with feigning weakness, and so far, Austria is the one nation that has displayed a continuing willingness to attack me. I have been keeping my land tech level slightly lower than Austria's, which seems to be key to their continuing willingness to attack me.
Does anyone out there have any pointers on milking defensive wars? And/or suggestions on provoking nations into attacking? I've got -200 relations w/ pretty much the whole world, and beyond that the Insult option doesn't seem to do any good. I have gotten better at using warnings and trade to pick up CBs, but I've never managed to provoke an attack.
