If you were my customer my only concern would be you withdrawing your winnings and moving to another out. A man with nearly 30 years of capping under his belt certainly knows playing multiple -.5 -170 games plays right into the bookies hands. If you go 1-1 or 2-2 you lose a nice chunk of money, if I go 1-1 or 2-2 I show a profit, understand?
The type of player that worries me is the one who takes +.5 +150. If this type of player gets hot it is alot harder to recover my losses, not to mention a book never wants a player for a partner.
I don't mean to insult you but your plays are square and represent a opportunity for me to make money. Over the longhaul I will bust you, your money mgt is weak and your plays represent no LONGTERM value
