indexing strategy for 65000 unique pages

Not at all. Don't forget that Google won't index (nor even crawl, I think) everything at once, so it doesn't matter too much whether you put them up gradually or all in one go. If they're going to be indexed, they'll be indexed; if they're not (for the time being), they won't be.

There is something to be said for putting up pages gradually, however. When Google sees that you have new content each time it visits, it tends to schedule its crawler to visit more frequently. Thus, the more often your site is updated, the faster Google will crawl and index new content (providing it's prepared to index the new content - which, again, depends on the number of site-wide backlinks and overall authority).

Not really. You can't really force Google to index anything. As I say, beyond a certain point, whether something gets indexed or not is very much dependent on the total number (and strength) of incoming links to your site (not necessarily to each new, individual page). So providing your new pages are easily found by their crawlers when they spider your site, and/or if you've submitted a sitemap as per the above post, you've done all you really can - with exception to building links to those new pages - to help them be indexed.

I know it sounds fishy but i created 65000 unique pages each seo optimized and 65% differant from each other.

I just don't have any experience wich strategy to use to get this indexed. Ofcourse adding all 65000 to google will be crazy. But how many pages could you add each week a few hunderd/thousands?

This will be offered soon as a service in the wf. If you are getting your traffic now from say 100 indexed pages will getting say 3000 indexed pages improve your site traffic
