Line Betting (general terms)
It is an even-money paid bet where you take a position either
side of two possible outcomes of the event. e.g. England runs
vs. Australia may quote 225-230 (a bit like a spread), thats
called the Line. Selling the Line means you win if they score
less than 225 and Buying the line means
winning if they score more than 230. This is popular in the
U.S.
