Many '
poker strategy' sites will have affiliate links, and are kind of competing with cardschat for your sign-up dollars, so we can't post much in that regard.
There are some good strategy articles on CardsChat, though, and more than that there are various discussions of
bankroll management, table selection, table image, hand analysis and so on in the forums - there's a wealth of information on here if you browse through enough, or search for things like 'starting
hands'.
Looking through discussions of other people's hands will tend to give you multiple views on how a hand could have been looked at, which can help to get a feel for the range of approaches to a situation.
