Opening 3-1: Making the 5-Point
The "Golden Point" Move
Strategic Insight & Master Lesson
Rolling 3-1 is mathematically the strongest opening roll in Backgammon. You move one checker from the 8-point to the 5-point (3 pips) and one from the 6-point to the 5-point (1 pip).
Grandmaster Key Takeaways
- 3-1 is the strongest opening roll in Backgammon, securing your 5-point.
- 4-2 and 5-3 should always be used to make the 4-point and 3-point in your home board.
- 6-5 is "Lover’s Leap", safely advancing a back checker 11 pips to the midpoint (13-point).
- Splitting with small rolls (like 2-1 or 4-3) prepares advanced anchors in the opponent’s home board.
Why the Opening Move Sets the Entire Match Dynamic
Backgammon opening rolls are played with one die each to determine who moves first. If both players roll the same number, the dice are rolled again. This means the opening move can NEVER be a double (such as 1-1, 2-2, or 6-6). There are exactly 15 distinct combinations possible.
Decades of computer rollouts (Snowie, eXtreme Gammon) and mathematical probability analysis have proven that certain opening choices vastly outperform others in long-term winning equity.
The "Make Points" Group: 3-1, 4-2, 5-3, and 6-1
Whenever your opening roll allows you to secure a new point without leaving a blot, it is almost universally best to make that point.
3-1 (8/5, 6/5): The unquestioned king of openings. Securing the 5-point (the Golden Point) makes it substantially harder for the opponent to enter from the bar or escape their back checkers.
4-2 (8/4, 6/4): Secures your 4-point, cementing a deep home-board anchor that will threaten the enemy throughout the early game.
5-3 (8/3, 6/3): Secures the 3-point. While slightly deeper than ideal, creating an anchor without risk is always high equity.
6-1 (13/7, 8/7): Makes the 7-point (Bar-point). This acts as a gateway block, preventing opponent runners on point 24 from escaping with a single 6 roll.
The "Running" Moves: 6-5 (Lover’s Leap)
6-5 (24/13): Known affectionately across the centuries as "Lover’s Leap". Rolling 6-5 allows you to move one of your two deepest checkers on point 24 all the way to your safe midpoint on point 13.
By leaping immediately, you cut your back liability in half and instantly take a commanding lead in the race count.
The "Splitting and Slotting" Dilemma: 2-1, 4-3, 5-2, and 6-4
When no point can be made, modern grandmasters recommend either splitting your back checkers (e.g. 24/23 with 2-1 or 24/20 with 4-3) to prepare advanced defensive anchors, or running a checker to the outer board.
Avoid risky "slotting" of the 5-point unless playing in match situations that require ultra-aggressive variance.
