• A betting result on a point-spread wager. For a favourite to cover, it has to win by more than the spread; an underdog covers by winning outright or losing by less than the spread.
   
• A betting technique where in case of a wrong guess you will receive a part of or even the whole stake. Simply saying, bettor places a wage on the option opposite to the one he chose before. A properly picked bet eliminates losses in the worst case, and in the best - brings you profit.
