A +1.5 spread is commonly seen in baseball betting, the standard runline  for MLB. This spread means the underdog must win outright or lose by exactly one run to cover the spread. Alternatively, a -1.5 spread means that the favorite must win by at least two runs. Many baseball games are decided by fewer than two runs.

An accumulator bet involves combining multiple bets or selections into a single wager, all selections must win for the bet to be successful. This type of multiple betting is also known as Parlay or Accumulator betting. Accumulator bets are potentially lucrative as the odds are greater therefore requiring a lower stake.
