Do professional scrabble players use fake words as a strategy? I assumed that (minus the weirdo savant playing in a foreign language), everyone at the professional level has an extensive vocabulary for which it would be difficult to bluff.
Everyone knows words like "fork", "vogue" and "alligator" but only scrabble players know whether or not "forkier", "defork", "voguier", "voguiest", "alligatored" and "alligate" are real words.
The CSW is the official English word list used internationally (outside of the US/Thailand/Canada because we just HAD to be different) and contains over a quarter of a million words. Unless you're at the UPPER OF UPPER ECHELONS, there's a chance a crafty player could slip a phony in by hooking an "S" on the board or some other subtle stem - especially with the pressure of time controls.
