Black to Play 4-5In our blog post of November 15 we discussed the various stages of a containment game, and outlined some rules for guiding your play. Leading off the rules was an important one: Don’t break your 6-prime!

Running off an Anchor

Black to Play 5-3
One-way holding games are, for the most part, pretty easy to play. You hold onto your anchor, watch your opponent try to clear points, wait for a shot, and then hopefully hit it. Alternatively, you roll a 6-6 or 5-5 somewhere in this process and move into a race where you’re close to even or maybe a little ahead.

Playing a Random 6 from the Bar

White – Pips 168 (=)

Black – Pips 168 (=)
Black to Play 6-2
This position shows a typically awkward moment in the early game. Black’s game is temporarily a little loose, and now he throws a 2-6 from the bar.

Sometimes a six from the bar will allow us to do something obvious and good, like hitting a blot or building a point. When we can’t do anything good, we’re usually faced with a choice among several unappetizing alternatives. That’s the case here. We have four legal sixes: 8/2, 13/7, 21/15, and 22/16. None look great, but we have to pick one. Let’s set up some guidelines and see if they can lead us to the least unappealing six.

Black to Play 2-1Let’s suppose you hold an anchor in your opponent’s board. Dutifully you hang on and wait for your shot. The shot comes and you hit it. Huzzah! Now what?
