Which chess player has the most openings named after him? I always thought it was interesting that chess players had openings named after them.  The game of chess has only been popular and organized for about 150 years, yet all the most popular openings and most of their sub-variations have already been named, many after players from the 19th or early 20th centuries.  In five hundred years, will all these basic openings still be named after Morphy, Steinitz, Capablanca, and Lasker?  But I digress.

Which player has had the most openings or opening variations named after him?  My guesses would be Botvinnik or Aljechin (Alekhine).
Nimzovitch.

Notes: Simon Winawer played the "Winawer Variation" of the French Defense once in his entire career; why it's named after him instead of Nimzovitch who really popularized it is a mystery (to me at least). And no, Winawer does not deserve the credit for playing it first (if he even did that) many openings are named after the masters who hammered out the theory of them and/or made them popular. Ergo the "Advance Variation" of the French Defense should also be named after Nimzovitch!
