The baseball version of betting against the spread is the run line. On games in which one team is a big favorite, the run line typically adds 1.5 runs to one team or subtracts 1.5 runs from the other team. Scalp This word has several meanings. One use is to bet both sides on the money line in such a way as to guarantee profit. For example, if New York is playing Chicago and you bet New York -140 and Chicago +155, you have a 15 cent scalp. Another use of scalp is to describe what a bookie might do if he thinks a line is going to move. Suppose a bookie takes a bet on Dallas -6 from a sharp, and predicts that other bookie soon will be calling to also place bets on Dallas. If the bookie immediately bets Dallas -6 with other bookies and simultaneously changes the line at which he accepts bets to Dallas -7, he is said to be scalping.
