Nearly a decade later, even as he edited the draft of the preliminary Emancipation Proclamation in August of 1862, Lincoln hosted a delegation of freed slaves at the White House in the hopes of getting their support on a plan for colonization in Central America.
A 3-team parlay usually pays 6 to 1. If you made a $100 parlay and all three teams covered the spread, you would win $600. All of them need to cover the spread for you to win. If San Diego lost by exactly 6 (push/tie) and you won the other two games, the 3-team parlay would just be knocked down to a 2-teamer.
The benefit of the parlay is that there are much higher payoffs than placing each individual bet separately since the difficulty of hitting it is much higher. If any of the bets in the parlay lose, the entire parlay loses. If any of the plays in the parlay ties, or pushes, the parlay reverts to a lower number of teams with the odds reducing accordingly.
