Middle

A middle opportunity arises when you can bet both sides of a game at different point spreads, creating a window where both bets could win. If the final margin falls in that window, you win both bets. If not, you lose the vig on one side.

Middles most commonly occur when a line moves significantly. You might bet Team A -3 early in the week, then the line moves to Team A -7. If they win by 4, 5, or 6 points, both your bets win.

Middle opportunities offer positive expected value because the potential payoff of winning both sides far exceeds the cost of losing one side's vig. Professional bettors actively seek middling opportunities.
