surname, German, literally "tailor" (equivalent to English Snyder), from schneiden "to cut" (see schnitzel). As a verb meaning "to defeat thoroughly," it appears to be from the game of skat, 1885, where it describes an emphatic way of winning (another way is known as a Schwartz, another German surname). It is attested in German as a skat term by 1860.
In all simple bids, a player proposes to win the game, that is, make at least sixty-one points. With a strong hand he may bid to Schneider his opponents ; that is to prevent them from making thirty points. ["Trumps," "The American Hoyle," New York: 1885]
