Question on paying taxes on poker winnings.

[h_ven]

The last two weeks I've cahsed out $10,000. I won a $35,000 R&A and paradise and cashed some money out from the Empire500 deal. What do I do about paying taxes on these. I've talked to several people, some say I can get away with it since paradise is in another country, and some say I have to up to 40%. Please give me some comments.
