claiming ******** wins and losses on taxes

[nolefan]

I won some money last year ********- about $4600 from a fantasy football site and they sent me a 1099 miscellaneous income form. I am wondering what amount of ******** losses I can claim against these winnings and have it still look plausible to the IRS (if that's possible). Anybody ever done this? I read you can claim loses up to the amount of claimed winnings, true. Would appreciate any advice.
