well, if you always up your bets, you are bound to hit one and make your $500.... why not just bet $500 on one game... the whole stipulation that you would turn $100 into 500 makes it sound as though someone wiht $100 roll can do it. anyone can make $500 in a day with an enormous bank roll...
just my opinion...
either way, good luck on your positions tonight. i'm on the opposite game for the hawaii -17. good luck
