In the early stages of a long match, cube strategy should generally be the same as in money play. When one or both players are knocking on the door of victory, however, cube strategy becomes totally dependent on the score. Analyze the following positions, and determine whether or not you would send the cube over. The key questions to ask yourself are:

1. What are my chances of winning the match if I double?
2. What are my chances of winning the match if I don't double?
3. If I don't double, what are my chances of losing my market on the next roll?

In each case, you are Black, on roll, playing a 15-point match against competent opposition.
