The Online Poker Guide
Small poker guide. Very little content. Few promotion/reviews, tournament schedules and a bookstore.
Poker room review site and poker guide, with a UK focus. Includes 9 reviews, rules, tips & strategies, glossary, odds & rankings. Information is short, but quite good. The reviews are clearly structured and to the point, however not very critical. Very nice design and pedagogical structure. Part of commercial network of sites, with similar information. Recommended.
