James Holzhauer, a professional sports gambler whose parents could very well be an encyclopedia and a dictionary, has been wiping that bright blue Jeopardy! floor clean with his strategic aggressiveness since debuting on the show earlier this month. As of publishing time, he’s accrued just above $1 million in winnings over 14 consecutive games, an astonishing pace that should be making Jeopardy!’s greatest champion, Ken Jennings, shvitzing a bit. (He seems to be chill about it at the moment.)

But enough of his stats: Are you smarter than this punk? Think you have what it takes to beat him on a clue? Ha-ha, sure. Knock yourself out. Below are the 15 questions that, as of this publication, Holzhauer has so far buzzed in on and gotten incorrect, plus the category each question came from. Let’s see how much you actually know! And to check anything you might’ve gotten wrong, we’ve included an answer key at the bottom. Remember, you have about .05 seconds to form something in your head before he pounces on that buzzer. (Note: Like the show itself, this quiz acknowledges multiple answer variations as the correct response.)

Answers, descending from the top: Panic at the Disco; Gerald Ford; a dry run; the Quakers; the Tour de France; the Bill of Rights; fuel tanks; Normandy; Ben Affleck; Jerome Robbins; elk; correspondent; Billie Holiday; First Battle of Bull Run; Lake Geneva
