Alternate lines are spreads or totals offered at different numbers than the main line, with adjusted odds. If the main spread is -3 (-110), alternate lines might offer -1 (-160) or -7 (+150). They let you customize risk/reward but are typically less efficient than main lines.
Example
Main line: Chiefs -6.5 (-110). Alternate lines: Chiefs -3.5 (-200), Chiefs -10.5 (+140). You can take less risk at worse odds, or more risk for better payout. Sharps generally stick to main lines; alternates have wider margins.

They can be useful for same-game parlays where you want correlated outcomes. Taking a favorite at a smaller alternate spread with their team total over can make sense. But standalone, alternates usually carry more vig than main lines.
When should I use alternate lines?
When should I use alternate lines?
Consider alternates when: (1) you have strong conviction and want more action, (2) building correlated SGPs, or (3) the main line doesn't match your projection but an alternate does. Always compare the implied probabilities to your own.
