Questions and Answers
About the Rules of Backgammon
What is a "prime"?
A prime is a sequence of six consecutive blocks. When a prime is in place, none of the opponent's checkers can motion past as long as the prime remains intact. That's because a checker can't touch on downwardly on a blocked point and never moves more than six points in a single hop.
In the following example, Blood-red has constructed a prime on his side of the board and trapped White's outermost checker.
What does it mean to be "closed out"?
When your opponent constructs a prime in his dwelling house board then hits i of your blots, you are "closed out." Your hit checker will remain on the bar and you lot will non be able to brand whatsoever further move until the opponent opens i of the points in his abode board.
May I pass my turn if I don't like the numbers I've rolled?
You must always play the numbers you lot have rolled if there is any legal way to do so. There is no option to laissez passer your plough in backgammon, or to reroll any roll of the game.
Is there a limit to the number of checkers that tin can occupy a single signal?
In that location is no limit to the number of checkers that can be on one point. In fact, it is possible to have all fifteen of your checkers on one point at the same time (though this is very rare). When you lot have more than five checkers on a betoken, it is usually a good idea to stack some of the checkers on top of others.
Is there a limit to the number of checkers that tin can exist on the bar?
There is no limit to the number of checkers that can be on the bar. I have seen every bit many as 6 checkers on the bar at in one case.
Can I move other pieces during a plough in which I enter a homo from the bar?
Yes, if you take no other checkers on the bar, then you must use the remaining numbers of your curl to motility either the checker you just entered or other checkers. Only if yous tin't enter all of your checkers on the bar, then you must enter as many as you can and forfeit the residue of your turn.
Is stalemate possible in backgammon?
A stalemate position would be one in which neither player could make whatsoever future play. You tin can imagine such a position if both players had checkers on the bar and closed abode boards. Neither actor would be able to enter his checker or make any other move, and the game would be stuck.
But such a position cannot be reached through legal play. Here's why. Suppose a double closeout position were somehow possible. Either you or your opponent would have to shut your home board beginning. Let's say it's you.
- You can't close your board if you accept a checker on the bar. So your opponent must hit you sometime afterward yous close your lath.
- Your opponent tin't striking yous while your board is closed if he has a checker on the bar. So sometime after he hits you, you must hit him.
- Yous can't striking your opponent while you lot have a checker on the bar if his home board is airtight. So he presumably closes his board sometime afterwards y'all striking him.
- But if y'all hitting him, he will exist on the bar against your closed board and he won't be able to close his own board. So a double closeout position is incommunicable.
Do I accept to bear off a checker if I don't desire to?
The rules crave that you use both numbers of your curl (all four numbers of a double) if possible. If you tin can make moves which do non involve bearing off, y'all are free to practice so. Otherwise, y'all must bear off if that is your only legal play.
Here is an case of where begetting off is mandatory. White has rolled 4 and 3. In this position, he must bear off one checker from each of the iii and four points -- it's the only way he tin use the numbers he rolled.
Hither is an example where White may behave off either ane or two checkers. If White bears off two checkers, he will leave a blot. But this isn't necessary. Instead White can utilize his 2 to motility a checker from the 4 bespeak to the 2 betoken and and then employ the 4 to bear off one of the checkers on two signal. The event is one checker off and no blots.
Can I bear off from a lower point than the number I've rolled?
The only time you may behave off a checker from a point lower than the one indicated by your roll is when there are no checkers on any higher points. Yous may use a 5 to bear off from the three signal, for instance, only if you take no checkers on the the four point, five betoken, and vi signal (and, of course, no checkers outside your domicile board).
In the post-obit position, White can (and must) use the 6 to carry off 1 checker from the v bespeak, but he has no way to play the 4. White can't apply the 4 to bear off from the three signal because he still has a checker on the five point. And White can't motility the checker on the five point because it is blocked.
Here is another case. This time White is forbidden from bearing off the checker on the six signal! That's considering the only style he can use both of the numbers he rolled is to motion from the half dozen point to the two point (using the iv) and so acquit off one checker from the 5 signal (using the 6).
Can I double even if I have a checker on the bar?
Yes, you can double whatsoever time it is your plough and y'all have non yet rolled the dice. This even includes turns in which you don't get to curlicue because yous have checker on the bar and your opponent's board is closed.
Is there a limit to the number of times a double may be offered in ane game?
No, there is no limit. The only restriction is that the same actor cannot double twice in a row.
What is a raccoon? An otter?
Let's start at the beginning. If 1 thespian (A) thinks he has an advantage in the game, he tin double his opponent (B). If B accepts the double, the cube is now at two and the game is worth two points. This is a manifestly, ordinary double.
In that location is an optional rule that says if B thinks he is the favorite after accepting a double, he may immediately turn the cube to 4 without forfeiting his option to double again later. This is called a "beaver."
Some people play with some other dominion that says if A still believes he is the favorite after a beaver from B, he may immediately turn the cube another notch to 8. This is called a "raccoon."
And some people play with yet another rule that says if B still believes he is the favorite afterward a raccoon from A, he may immediately turn the cube some other notch to 16. This is called an "otter" or other like animal.
Throughout all these immediate redoubles (beaver, raccoon, or otter) the cube does not alter hands. Only a regular double transfers ownership of the cube. And all the fauna redoubles must exist fabricated immediately afterward the initial double has been accepted. In that location can be no intervening dice rolls or checker moves.
Is it legal/ethical to double on your first turn?
Suppose my opponent and I have just finished the Crawford game. I am trailing to my opponent who needs just i more point to win the match. Am I doing anything wrong if I double on my starting time turn of the next game?
Doubling at your first opportunity when you are trailing subsequently the Crawford game is perfectly adequate. In fact information technology is a proficient strategy because if you lot lose this game you will lose the match anyhow. And doubling right away guarantees that you will get at to the lowest degree two points if you win.
At that place is no reason to experience guilty about doubling before you take a clear lead. Yous've already paid a substantial price in not being able to double during the Crawford game. Now that you have the cube once more, you should use it to your maximum advantage.
A number of years ago some tournaments used a rule chosen the Holland rule. This rule says that, in games after the Crawford game, the trailing thespian cannot double until his third turn. The rule is rarely used today.
