Ok, as Holland, I like to explode early. If you want to expand very slowly, colonize a ton, then sure, NTP, QFTNW are good. For me, I break alliance day one. Ask for mil access from Burgandy. Build troops. As soon as timer expires, wardec Hanuit. Break PU, get new king. Don't vassalize or you'll be at war with Burgandy soon, but occupy for sure. Vassalize any allies he calls in that are not on the normal Burgundian target list in the first 20 years. Get every drop of Prestige and money you can. Do this fairly quickly and the war will be over before the first Bohemian troops arrive. Peace out when you need to, you should be 100% no matter what since you occupy Hanuit. Buy a legitimacy guy and a prestige guy. RM with people you don't care about in the long term, Naples, Irish minors, etc to boost your legit. RM the ppl you want to force PU and do so. Within the first 20 years, you're tech leader in all categories and with Mil drill, have no problem mopping up all the chumps nearby. Once you've got a few countries in PU's and a few vassals, your BB might be a bit high, but as it comes down, your tradiness goes up. You start the trade game a decade or two later, but you have a nice inheritance comming now, and you're in possition to start grabbing provinces from Burgandy as soon as they fight France. If France already beat them up, you don't need to wait. By 1450, you should already be unstoppable using this method.
