backgammon isas easy as...

By Steve Sax

To progress from beginner to intermediate to champion, you have

to master the basics of the game. They may seem complex, but are

as easy as one, two, three.

By that I mean that there are three basic tasks which you should always be

looking to execute. They are: (1) Can I make a new point? (2) Can I hit one

or more of my opponent’s checkers? (3) Can I escape one or more of my

back checkers?

Let’s analyze each of these tasks.

Making a New PointThe first task of checker play is, “Can I make a new point?” For those of

you who are absolutely new to the game, a point is formed by putting two

of your checkers on the same triangle. Interestingly, the space occupied by

that triangle is also called a point, but that’s beside the point.

There are many reasons to make points and I’ll go over a few of them now.

(1) If you make a point in your home board it can block your opponent’s forward progress. Additionally, a home-board point can

prohibit entry of an enemy checker from the bar.

(2) Points outside your home board can block your opponent’s forward progress, but can’t

keep him from entering from the bar.

(3) If you assemble enough points in a row you can severely restrict your opponent’s forward progress; and if you build a wall or “prime”

of six points in a row, he can’t escape at all until later in the game when you elect, or are forced, to disassemble that prime.

(4) Points can also be used as landing spots for you to safely move your checkers from one quadrant of the board to another.

come home. These anchors can also serve as landing spots for bringing checkers back into battle.

Hitting Your Opponent’s CheckersThe second basic task of checker play is,

“Can I hit one of my opponent’s checkers?”

Here are some reasons why hitting your

opponent’s checker(s) can be beneficial.

Since backgammon is, like Parcheesi or

Sorry!, fundamentally a racing game, you

gain ground in the race by sending your

opponent’s checkers back to the bar. That,

for a checker, is like a player being sent

to the penalty box in hockey: he cannot

come back to play in the game until the

penalty is over.

The substance of that penalty is that your opponent cannot play

until he rolls a number that corresponds with a point in your home

board not occupied by two or more of your checkers.

The ultimate penalty occurs when you have a closed board and

you hit one of your opponent’s checkers. In that case, he can’t

enter until you elect to, or are forced to, break your home board.

Usually you will not have a closed board, but the more points you

have in your board, the more difficult it will be for your opponent

to bring checkers in from the bar and back into the battle.

A second reason for hitting your opponent’s checkers is that they

cannot then be used to make points, primes, and closed boards

to block you!

A third reason for hitting is to take half of the opponent’s roll away. Once you hit him, he will be unable to make new points in his

home board unless he happens to come in from the bar with a double.

Escaping Your Back CheckersThe third task of basic checker play is to escape your back checkers.

The reason this is important is that you can’t win the game until you bear off all of your pieces, and you cannot do that until you get

all of your checkers home. You should usually try to complete this task early in the game before your opponent can “prime you in.”

If one or more of your checkers is trapped behind a prime and you don’t have a prime of your own to trap your opponent’s checkers,

then you are likely to lose the game.

Weighing ChoicesThese three basic checker-play goals are

each important; but none of them is more

important than any other outside of a

specific context.

One useful rule of thumb is that if you have

a play that does more than one of these

tasks at the same time as opposed to a play

that does only one, there is a reasonable

chance that the double-barreled play will

be preferable.

In Position 10 Black has a 1 and a 3 to play.

He can hit White’s checker on the 20 point or

he can make his own five point. Both moves

have benefits for Black, but making his own

five point accomplishes two tasks (hitting

and making a new point) whereas hitting

on the 20 point only accomplishes one.

In Position 11, let’s take a look at two of Black’s choices. He can

either hit and escape (accomplishing two tasks), or he can make

his own five point (accomplishing only one task). In this case, it’s

right to hit and escape rather than to make a good point in your

home board because you not only send your opponent back in the

race, but you hamper his efforts to block you in his home board.

A third example of accomplishing two tasks versus one arises when you can escape and make a new point, as opposed to simply mak-

ing a new point. An example is Position 12 below, which hits as well.

Some of the best possible rolls are ones in

which all three tasks are accomplished in

one move. Usually this occurs when you

roll a double, as then you can move four

different checkers in one play. In Position

13, Black rolls a 5-5: a fantastic roll, but

how do we play it?

One choice is to close your board by mak-

ing your three and one points; but then you

still have to escape your back checker in

order to win the game.

A better option is to run from the 23 point

to the 13 point and make your own ace

point. This play accomplishes all three tasks

at the same time. And while it isn’t always

correct to achieve those three tasks, a play

that does so should certainly be on the top

of your list of candidate moves.

You can accomplish two tasks by making

your ace-point (hitting and making a new

point), but it is a little better to simply make

your five point.

Why? The reason is that the theory of

tasks has to take into account not only the

quantity of tasks you can accomplish but

their quality as well.

In this example, you are better off making

the five point because it starts a prime. By

hitting and making your ace point, you do

make a new point and put your opponent

on the bar, but you have created a huge gap

in your board and will be hard pressed to

contain him.

Preparing for Next TimeThis brings us to the last theme of this

article. What if you can’t accomplish any

of the three basic tasks?

In that case, you must improvise — by which

I mean you should prepare to accomplish

one of the tasks.

For example: if you can’t make a new point,

mobilize builders to try to make a new point

on your next roll. Position 15 (below) is an

example of this theme.

Black can’t hit, make a new point, or escape, but he can bring builders down from his midpoint to make a new point on the next roll.

There is risk involved (those builders are blots which can be hit), but at least Black is preparing to fulfill one of his key tasks.

To summarize: we have examined a number of examples

where you should attempt to accomplish at least one of

the three basic tasks of backgammon checker play: to

hit; to make a new point; or to escape a back checker.

This doesn’t address the difficult question of which one of these

three you should choose if you can do only one. That is beyond

the scope of this article.

I hope that this introduction to the basic concepts of checker

play will add to your enjoyment of the game and improve your

winning chances.

Until next time, play well and have fun.

*: The asterisk represents the fact that one player is hitting the other player's checker. This is displayed at selected diagrams in the rollout

data graphic beneath positions. For example, in Position 10 the correct move is (8-5*, 6-5). That means one Black checker was moved

from the eight point to the five point with the 3, hitting White and sending that checker to the bar. And also one checker was moved

from the six point to the five point with the 1.

Advanced Anchor: A point in your opponent’s home board that is close to your opponent’s outfield. Usually this would be the 20 or

21 point (your opponent’s 5 or 4 point).

Anchor: Any point you hold in your opponent’s home board.

Bar: The strip that bisects the board where checkers are sent after they have been hit. All of a player’s checkers on the bar must be

brought into play before that player can move any other of his own checkers.

Blitz: An effort to close all the points of your home board while trapping one or more of your opponent’s checkers on the bar.

Checker: One of the fifteen disks which you must navigate around the board.

Gap: Any space in between points you have in a prime. Generally, the larger the gap, the harder it is to contain your opponent’s checkers.

Home Board: The six points closest to your bear-off tray. Your goal is to get all fifteen of your checkers into your home board and

then take them off the board into that tray.

Point: Any two (or more) checkers of the same color on the same triangle. Your opponent may jump over your point, but not land on top

of it. A point is also one of the 24 triangles on the board which you must land your checkers on as you advance them around the board.

Prime: Any number of consecutive points assembled for the purpose of blocking your opponent in. The longer the prime, the more

difficult it is for your opponent to escape. If you have six or more points in a row (a six-prime), your opponent can’t escape until you

break that prime.

Quadrant: One of four sections of six points on the board. They include your home board, your outfield, your opponent’s outfield,

and your opponent’s home board.
