Answers.Text: Remember a multi-threaded application can also run on a single core - you just set the thread to 1. "Deep Fritz" sounded better than "Strong Fritz" or just simply "Fritz". As I said, calling something "deep" is more like an attempt for better promotion.

  It used to be the case that the "Deep" specified the multiprocessor version. At least for Fritz, Shredder and so on, the "old" engines. But I guess nowadays every engine is a multi processor engine …
  
  This naming trend was surely started by [Deep Thought](http://en.wikipedia.org/wiki/Deep_Thought_(chess_computer)), the first seriously strong IBM chess machine. And of course Deep Thought was named after the famous computer from the hitchhiker's guide to the galaxy.

  "Deep" is simply just a marketing technique. It's a tactic to sell you more, and sell you at a higher price.
  
  Consider this, "Fritz" and "Deep Fritz". What does that mean to an average user? "Fritz" might sell for $50, "Deep Fritz" might sell for $100. What would an average user with little chess engine knowledge think?
  
  They might think like this: "Oh, it's a DEEP version of the software, so it must be GOOD because DEEP Blue has beaten the World Champion. This software must be DEEP. Why not pay $50 more for a world-champion-level product?".
  
  Chessbase is trying to paint a mental picture on you:
  
  "DEEP" Fritz == "DEEP" Blue > Kasparov == World Champion > the $50 difference.
  
  Technically, Chessbase explains the difference is due to multi-threading. But this is just an excuse. They simply make the "normal" version single-threaded. It's a 10s work. Everyone can do it.
  
  This is really a very standard marketing technique. What do you think when someone says "I have a new porsche car"? Probably something like, "rich", "successful" etc.
