I think all the short stories in Ray Bradbury's collection "The Illustrated Man" have twists. Strong recommend, if you've never read it.<p><a href="https://en.wikipedia.org/wiki/The_Illustrated_Man" rel="nofollow">https://en.wikipedia.org/wiki/The_Illustrated_Man</a><p>The Sentinel, by Arthur C. Clarke, certainly has a twist. But it doesn't come as a surprise nowadays, because everyone's seen 2001.<p>Hmmm. Many of Kurt Vonnegut's stories have astonishing twists, but I can't think of any that are short (although I guess most of the early ones were initially magazine serials).
William Gibson's "Burning Chrome".<p>(Provided the rough skeleton for the movie "Johnny Mnemonic".) Appears in a collection of Gibson stories also titled Burning Chrome.
Older stuff, Man-Kzin Wars, Stainless Steel Rat<p>Newer stuff, We Are Bob, Undying Mercenaries. Expeditionary Force, Old Man Wars<p>Risky Stuff, Forbidden Thoughts<p>All kinds of twists in the stories.
