Evaluating Candidate Plays

Apr 3, 2018 | Backgammon Problems: Early Game

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

Mar 15, 2018 | Backgammon Problems: Early Game

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

Feb 16, 2018 | Backgammon Generally

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

Feb 1, 2018 | Backgammon Problems: Middle Game

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

Nov 22, 2017 | Backgammon Problems: Priming Games

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.
