Greetings, BJT.

I am a winning blackjack tournament player (have won $20K in the last 2 months alone) & am wondering my options on paying the taxes on my winnings....... aside from choosing the lower amount of tax to pay on "Married Filing Jointly" & "Married filing separately" can anyone tell me how tournament winnings are taxed & any other options I may have for lowering the amount I have to pay? I got a form 1099, I believe, in Dec but unfortunately misplaced it...
thanks in advance
