  [They can't](https://chess.stackexchange.com/questions/7821/can-a-human-defeat-an-engine-in-a-10-game-match-if-he-is-given-the-white-pieces/23162#23162). Engines are absurdly strong relative to humans these days, and Stockfish should be fully expected to beat top human GMs 10-0 without much trouble. In fact, [they already have](https://www.youtube.com/watch?v=bIQDo0ReY10) - and that's in spite of Komodo being a few tens of elo weaker than Stockfish. Book lines with high draw rates don't matter: either the engine avoids it, or they play it and win anyway because when the human inevitably makes a mistake, the computer capitalizes.
  
  Caveats:
  
  * The engine needs to be properly configured. Stockfish comes with a "contempt" setting that needs to be turned up. This makes the program avoid quick draws.
  * The other top engine right now, Leela, does not have a contempt setting. This means humans can indeed [score draws against it](https://www.chessable.com/blog/2018/12/10/alphazero-google-david-howell-draw/) (this was against AlphaZero, which is similar to Leela and probably weaker than the latest versions). However: humans still cannot beat Leela/AlphaZero.
  * The engine needs to run on reasonably strong hardware. These days engines will beat humans even on modest hardware, but if you try very very modest hardware such that the engine only manages to search a few thousand positions per second, humans might still win.
  
  **Edit**: for the strategy you suggested, this was what happened when [GM Michael Adams tried it against Hydra in 2005](https://en.chessbase.com/post/adams-vs-hydra-the-execution-continues). Link to [game](https://www.chessgames.com/perl/chessgame?gid=1342025) if you want to see the moves.
