In ProbabilityBasketball_SM, you don't pick against the spread. You gain or lose points in the contest depending only on whether the team you've picked as favorite (at higher than 50%) wins or loses, not the margin of victory. The more bold your pick is (moving toward 100% for the favorite), the more points you can gain or lose. If you pick 50% for both teams, or do not make a pick for a game, you will neither gain nor lose points, regardless of the outcome for that game. This unique scoring function ensures that the players most accurately estimating the probabilities (strengths of the teams) in each game will score the most points on average.
