Hrqls: When bearing in it is best to aim for the points 4, 5 and 6. The low points can very well remain empty. The reason is that all dices below 4 will play fine even if the low points are empty (e.g. with a 3 you play 6/3, keeping a fine distribution). By contrast, an empty 4-point (for instance) is a nuisance, because all fours have to be played 6/2 or 5/1, accumulating checkers on the low points, that are likely to waste pips later.

So in your example, the move is definitely 8/6 8/4.
