It depends on what you want to do.
Do you want to play OTB tournaments? Most require you bring your own board, so you'll need one. However, you might find that being a member of a local club will have the club lend you material for tounreys, so you might want to ask.
If you don't want to play in tourneys, you obviously don't need a tourney set.
Now, think about your training regimen. You should buy a non-paper board, even a very cheap one, for analysing games, going through chess magazines and puzzle solving. Again, these can come cheap if you look around.
It's up to you to decide what training tools you need and want. Books might be good, but the premium membership here is also very benificial. At your level, you need to train tactics a lot, so try the tactics trainer here, and also check out chesstempo.com
You'll also want to train endgames and basic positional play-look around to see what training tools are availiable to you.
And one of the best things you can do is check out a local club. You'll play games, and the players oftne go out of their way to help you see the mistakes you made.
Errr~ i just have a second-hand chess board (already teared many times since it is paper) plastic chessmen (my King had lost his head ! Both !) and ive no books neither clocks.
so can anyone suggest what to do now ? do i need to buy a new chess set ? does it need to be the tournament set or just casual set ? do i need a clock ? a book (which book) ?
