The live betting moneyline is the plainest market: a price on who wins, with no points added. In a sport with draws the same idea becomes 1x2, where 1 is the home side, x the draw and 2 the away side. As the clock runs down, the price on a leading side shortens fast, and the draw in a level game grows more likely each minute. Late in a match the live moneyline often pays very little on the side in front.
How to live bet soccer and football sensibly starts with the pace of each game. A goal changes every price at once, and a red card changes the rest of the match. A live betting football strategy that holds up is usually narrow: a few markets, a set stake, and prices judged against what the game shows. Tennis moves in bursts instead. A live betting tennis strategy watches serve, since each game favours the server and each break shifts the odds.
