If you google, blocking in acey deucey heres what it says


Strategy: Because the roll of 1-2 is so powerful, luck plays a greater part in acey-deucey than in regular backgammon. You are never completely out of a game. On the other hand, since you start with fifteen men back, there is some added opportunity for skill in placing your checkers to block the opponent.

Typical strategy is to get at least half your checkers on the board as quickly as possible and form them into a blockade.
