That would be a great idea - one that I have recently looked into. It would allow you to deduct all of your expenses (internet, new computer, books, travel - for all you B&M players)and use them to offset any winnings. You would not be required to take your losses as itemized deductions. You could file a Schedule C with you "poker business" and even get the home/office deduction including mortgage interest and utilities. The IRS doesnt like this plan as much as I do.
The IRS puts a high standard on what they consider a professional gambler. Unfortunately, most of us would not qualify. This is a decent article on the subject:

I would be interested if anyone has tried this on previous returns and what degree of sucess they had.
