只有 when you might lose, can you employ "so-called tactics," and can you go after the substance.
Your options are reduced to two: win gracefully or win disgracefully. Which do you choose? And if your options are lose or win, which one do you want then?
When everyone assumes you will win, not pursuing a graceful victory is, in everyone's eyes, tantamount to losing.
If you are bound to win no matter what, then you cannot resort to tactics—because this is your moment to flex, to build your image.
