Should Black
double to 4?

As the beginner (black) prepared to roll, he was more than a 2 to 1 underdog (25 to 11, to be exact) to come in on white’s 4 point. But had the beginner thought of it, there was a clever doubling tactic to be employed in this position. Even though he is the underdog, it is imperative that he now redouble.

In order to overcome the expert, he will have to win this game; thus he must double against the odds. In this position the expert would prefer not to be doubled. If the beginner rolls a 4, he will deal the expert a stunning psychological blow; he will almost certainly win 8 points, and the match will be in jeopardy.

If the beginner fails to hit the blot, he will fall behind 10–3 or possibly even 14–3. But if he hits, the score could be 11–6 in his favor.
