Evaluating Candidate Plays

While many plays in backgammon are virtually forced, other situations may leave you with five or more reasonable alternatives. This is especially true of doubles, where the number of possibilities may be even higher.

In such situations, you need a systematic approach to finding the best play. Most players react haphazardly in these situations. They look for a good play, think about it for a few moments, and only look for a second or third play if the first play doesn’t look appealing. If the second play doesn’t look good after a moment or two, they may bounce back to their first play, or cast around for another. The result is a chaotic decision process that may well overlook the best play.

Fighting Stacked Positions

One common dilemma that players routinely face is that of hitting a tasty blot or making a strong blocking point. In very general terms, hitting the blot is most likely right. Hitting both gains ground in the race and prevents your opponent from improving his structure, which in normal positions will outweigh other choices.

As your opponent’s position becomes stacked and stripped, however, hitting blots recedes in importance while building blocking points grows. The reason has to do with timing. A stacked position can be repaired, but typically some time is required. A game with hitting and recirculating of checkers provides exactly that sort of time. A prime, however, tends to shorten the game, as a single bad roll can destroy the weaker player’s position in an instant. By building a prime, the aggressor can accelerate the crisis point to his advantage.

Evaluating Early Doubles

When contemplating a middle game double, don’t make the mistake of looking only at your position. Remember to look just as carefully at the weaknesses in your opponent’s position. It may be his weakness, rather than your strength, that gives you a good double.

Prince Alexis Obolensky – The Father of Modern Backgammon

This year, Prince Alexis Obolensky was elected to the American Backgammon Hall of Fame. (I always thought he should have been elected with the first class of inductees, but better late than never.) For those who aren’t familiar with Oby or his accomplishments, here’s a brief biographical sketch.

The Tempo Hit

 

In backgammon, most hits are done for one of two reasons: to gain ground in the race, or to attack a key point. A rarer, but still important use of the hit, is a defensive idea called the tempo play. Here the plan is to prevent your opponent from using his whole roll to do something good. By hitting (usually in your home board), you force him to spend half his roll coming in from the bar, so he’s not in position to do something devastating elsewhere on the board.

Consider All Possibilities

 

A lot of backgammon positions are pretty simple: the right play is either forced or completely obvious. Many others involve a clear decision between two very different alternatives. These problems may be hard to solve, but at least the choices are clear.

Some positions, however, involve a lot of possible plays, all of which are somewhat reasonable. These positions can be very tricky, and one of the dangers is overlooking the best play altogether while sorting through the wealth of possibilities. Be alert, and try to enumerate all the plays before starting to rank them.

Software Review: eXtreme Gammon

Some product reviews are hard to write. Do I like this product? Do I really like this product? Can I wholeheartedly recommend it, or do I have a few lingering reservations?

Fortunately, eXtreme Gammon (or ‘XG’ as it’s known in the backgammon world) presents no such problems. It’s the best backgammon software available, and if you’re a serious player (or aspire to be one) you have to have it. Period.

Bearing Off to Win a Gammon

 

Consider the following problem, which arose in a recent chouette:

White – Pips 118

Black to Play 4-4

As the captain, I had a 4-4 to play. Three plays were possible.

Equipment Review: The BoneClub Set

The modern backgammon boom continues apace, with new players, tournaments and clubs appearing on a regular basis. New players require new books and new equipment, and thankfully suppliers are appearing to meet the need.

I recently received for review a set from one of the newest suppliers, Bone.Club. The company is located in the U.K. but sells worldwide through its website, https://www.boneclub.co.uk. I picked a color scheme called ‘A Kind of Blue’ (blue, black, and yellow), but several other color schemes are available, such as Purple Rain (red, blue, and purple), Green Dream (green, black, and orange), and others. The colors are all sharp and vivid, which makes for a very impressive-looking set. Here’s a picture of the board I received, showing the striking colors.

Boston Quiz Contest, Part 1

The backgammon boom continues apace, with new tournaments popping up on the calendar on a regular basis. Two new tournaments appeared in just the past month: the Boston Open (Feb. 23-26) and the Viking Classic in Bloomington, MN (Mar. 9-12). Both were well attended, with 82 players in Boston and 83 players in Minnesota, very strong numbers for first-time events.

To help kick off the Boston tournament, I created a quiz contest for Sunday morning, with no entry fee and a $100 prize to the winner. Marty Storer of New Hampshire took first place with an outstanding score of 17/20, closely followed by Dennis Culpepper of Virginia with 16/20.

The collection of problems in the quiz is a little unusual. There aren’t any weird, tricky positions or difficult cube decisions based on match score considerations. It’s just a group of pretty normal positions where the choice is between two or three reasonable-looking plays. The idea here is to understand where you want to put your checkers when there’s nothing decisive to do this turn.

More on Hitting

In the last blog post we looked at some hitting problems in the early game. In this post we’ll look at a couple of more examples where hitting is one possibility.

When you have a chance to hit on your opponent’s side of the board in the early game, it’s usually a pretty easy choice. Gaining a lot of ground in the race, advancing your back checkers, and taking away at least half your opponent’s roll are so important that such hits are usually routinely correct, and even when wrong are rarely wrong by much.

Hitting on your own side of the board is more problematic. Merely hitting is no longer enough of a rationale. Here are some of the other questions you need to ask:
