Definition
A turn is a rebuttal that takes an opponent's argument and shows it actually supports your side instead of theirs. Rather than denying the opponent's claim, a turn accepts some or all of it and reframes its consequence. A link turn argues that the mechanism the opponent described actually causes the opposite effect; an impact turn argues that the outcome the opponent called bad is actually good, or vice versa.
Example
An opponent argues that a proposed policy will increase automation and therefore cost jobs. A link turn responds: "Automation under this policy targets dangerous manual tasks, not the roles this industry actually employs people in, so the job loss mechanism does not apply here." An impact turn takes a different path: "Even granting some job loss, the same automation reduces workplace injuries significantly, which outweighs the harm described."
Common mistakes
A turn only works if the judge can clearly see what is being turned and why. Debaters sometimes assert "that's actually good for us" without explaining the mechanism, which just sounds like a denial with extra confidence. A successful turn needs its own warrant, the same as any other argument: it is not enough to relabel the opponent's claim, you have to show why the labeled effect actually favors your side.
