Lets say a guy is a 1500 player but is pretty good with computers. His computer is 2yrs old---Dell inspiron 531. He downloads Stockfish 1.9---voila---he is now a grandmaster! Can he not beat any GM in the world? Just curious! How would he do in a 10 game match with Anand or Topalov?

Lets say you're in one of those open tournaments (anything goes). Naturally you want to load up with firepower so which chess engines do you want in the trenches with you when the going gets rough. And, you can have more than one!
