Congrats on the MTT win! I really think you should be concentrating on poker... it's SOOO much more profitable than sportsbetting. Read books, FTR forums, post hands, play as much as you can. The only reason I bet on sports so much is that it doesn't take much time and still satisfies my need for action I don't bet sports knowing I can win if I do it right, like I do with poker.

As for being a leech, don't worry about it. We've all been there. The biggest thing is bankroll management. I know you didn't start with much, but don't start risking more because you won that tourney
