There is one law of backgammon and this is that you are either better than your opponent or your opponent is better than you. If the difference is marginal than any superiority may not be visible and even if both yours and your opponents moves were analysed by computers then any differences may be highly marginal within short match distances anyway. But if the skill advantage is wide then as the inferior player then you absolutely owe it upon yourself to increase the luck factor within the game.
Let us look at this objectively, if your opponent was better than you then they would win more games and more matches and in short, more of everything simply because they are better than you. So if you could flip a coin to decide the match then this would be a great result for the inferior player as their chances of winning would have risen to 50%. This would be a blow for the superior player as their skill would have no impact on the result.
So it is then in the interests of the inferior player to increase the luck within the game and this means by use of the doubling cube. Offering and accepting doubles or re-doubling is a great way to make your superior opponent feel nervous about where the game is going. He wants the match to last as long as possible with as many games as possible but aggressive doubling is looking to shorten the length of the match around no more than several key games with high numbers on the cube.
