You are correct, I don'y need a capper. After selecting the games I like based on whatever factors in that sport I see as keys, I then look at the "price" the oddsmakers have placed on that game. If baseball for example, I have to decide if the high juice is appropriate for the matchup or is just plain too high. If it's a win no matter what the odds, I'll bet it! If it's high and I want to have action on that team, I will play a parlay .
As far as your racing forum, that' totally "greek" to me.
