Should you follow engine moves if you are under 2000?
Of course. Engines help reflect the theory we need to reach 2000. If you don't understand a move an engine makes, then you need to find out if it is a "computer move" or a sensible human move. With openings, this is very useful. It will even show "book moves" which are specifically moves which have been tested and verified by detectives, FBI, the KGB and sometimes Inspector Gadget. If all else fails you can hire a lawyer and sue Komodo and Stockfish. You will become rich like Trump just because you have a lower rating than 2000 but you know how to deal with it.
