I’ll ignore the snide comment as I don’t see where that came from, but…
Both Yahoo and Google (to different degrees) favor “exact match” and keyword density in URL (and page title too, but less so). poker.com and poker-online-put-hyphens-in.com do not start on a level playing field, to say the least. Exact match is certainly not everything, but again it is one thing that matters somewhat.
If you don’t agree, fine.
