I'm not going to bore you with all the complexities within money management as there are thousands of references online that go into detail of all the various aspects pertaining to this subject although it is just as; if not more, important than actually picking winners. Suffice it to say, my belief is never wager more than 3% of your total bankroll on any 1 play.
You must have a bankroll used strictly for your betting. Do not use money that could be used to pay bills, rent, etc. for betting.
Make your wager amounts proportionate to your current bankroll on every play.
You'll never see 5 star specials, locks of the month, plays of the year or any other garbage like that on this site. Unless otherwise specified, plays are based on 1 unit which equates to the standard $110 for most football or basketball spreads or totals. A -110 loser equates to -1.10 units and a winner on the same bet equates to +1.00 units so the juice is figured into all the plays.
A couple more things you won't see on this site are: (1) any full games in football or basketball that are priced at -150 or higher because I don't believe it's a good idea to lay that high a price on any of those outcomes and (2) NFL double digit favorites because the league is far too competitive.
