The opening 5-3 makes the 3-point: 8/3 6/3. For decades players treated 5-3 as a "builder" roll (13/8 13/10 was the old book play), but modern bots settled the argument: taking a real home-board point beats stacking builders. The 3-point is the deepest of the standard opening points, so it contributes less to priming than the 4- or 5-point — its value is in attack. With a two-point board you hit more confidently, and an early exchange of hits favours you clearly.
