Take point

The minimum winning probability at which taking a double breaks even — about 25% in money play; score-dependent in matches.

How it works in play

With a dead cube and no gammons the arithmetic is simple: take four times and win once, and you lose 3 × 2 and win 2, a net loss of 4 points, exactly what four passes cost. So 25% is break-even; owning the cube lowers it to about 21–22% in races, and gammon losses raise it.

  • Take — Accept a double, continuing the game at doubled stakes with cube ownership.
  • Drop — Decline a double (also "pass"), conceding the current cube value.
  • Cube life — The remaining value of cube ownership; quantified by Janowski’s live-cube calculations.
  • Match equity — The probability of winning the match from a given score.
  • Doubling window — The range of winning chances where doubling is correct and the opponent should still take.
