Problem of the Week #7: Solution
Here are two early game positions where Black has not much and White has an inner point and some pressure.
Cash game, center cube.
(a) Black to play 3-1.
(b) Black to play 4-2.
When Paul Magriel wrote his seminal book Backgammon in 1976, one chapter that was particularly noteworthy was entitled “The Golden Point”. There he described the importance of the 5-point, both for offensive and defensive purposes, and showed how making the 5-point was a key goal of early game play.
Over the years, theory has never really changed much on this point. We’ve found a few exceptions, and certainly expanded our knowledge of when to break the 5-point later in the game, but the 5-point remains a key opening goal in most positions.
The two examples given above are very typical cases. In each position, Black has a chance to make either the offensive 5-point (Position (a)) or the defensive 5-point (Position (b)). In each position, there are alternative that seem to have strong merit. In Position (a), Black’s rear checkers are under some pressure and seem to require a defensive anchor, which he can grab with 24/21 22/21. In Position (b), Black can actually hit while making a somewhat inferior anchor with 13/9* 24/22.
But in each case, simply making one of the 5-points is better. In Position (a), making his own 5-points smooths Black’s distribution while starting to put White under some pressure. In Position (b), grabbing the defensive 5-point with 24/20 22/20 prevents White from ever building a priming position, after which Black can start to build points on his side of the board.
It’s incredibly hard to go wrong by making one of the 5-points at an early stage. The exceptions are rare and tend to be exceptions by only small amounts. When in doubt, go for the 5-point.
Solutions:
Part (a): 8/5 6/5
Part (b): 24/20 22/20
