Learning to pose

In most games, the double six is the mandatory first pose. After that, the winner of the previous game gets free pose choice. Posing well is important since it gives the posing player or team the opportunity to control the initial game by developing dominoes/suites that are advantageous. There are three main objectives when you pose.

Play to your strengths Attack with your strongest suit. I.e play the suit where you have most representation. In a partner game, your partner should try to support you in this suit by a) also attacking with it b) avoid closing it c) encourage its development. When in doubt, a good fallback is to lead with the heaviest supported double in your hand.
Get rid of weaknesses Doubles are generally considered liabilities due to a) their limited playing options and b) their ability to get killed. The pose is an opportunity to discard a double to remove weaknesses from the hand.
Communicate with your partner The pose and how you pose can tell your partner how you want to proceed. A confident, aggressive pose may indicate that you are very strong in this suit. A non-double pose may indicate that you either have no doubles or are able to support all your doubles on your own.
