One angle I've heard about, though it may be intrusive and violate privacy,
is to find out when car/house payment is due or better yet child support payment.
Bet the player the week before because they will really hustle for the boleto
money on the next check. Just what I heard someone with access to that kind of
info was doing. Sounds logical. I want to make it clear that's just what I heard.
Don't know if it is true.
