Libertarian free will

Libertarian free will holds that genuine freedom requires real alternative possibilities that remain open right up to the moment of choice — not merely acting from one's own unforced desires (compatibilism's weaker standard), but a choice that nothing beforehand fully fixed.

Its appeal is that it preserves the strongest, most intuitive sense in which a person could genuinely have done otherwise, and so genuinely deserves praise or blame. Its standing cost is explaining how an uncaused (or self-caused) choice is not simply random — how flipping a coin inside your head, so to speak, is different from and better than an ordinary chain of causes, in a way that actually makes the outcome yours rather than merely unpredictable.
