First... Don't play a rebuy tourney if you can't allow yourself to rebuy. People will play loose and you need to loosen up too. Be ready to spend at least £25-£30...

I ALWAYS take the opportunity to rebuy before the first hand is dealt. Others will do that and you'll want to have a nice stack if you get to move in with the nuts. When pots get big, don't be afraid to move in with good drawing hands. You can always rebuy...

Finally... I assume they have an add-on as well. ALWAYS take the add-on except if your stack is so small you'll bust soon anyway, or if you have an extremely large stack (say 6-7x avg stack).

Good luck!
