This is most definitely wrong. There will be some draws and even a few wins, though that's very rare indeed.

When is the last time a human has beaten a computer in a fair chess game?

[nilslindemann]

A fair match has never been played between humans and computers. Let's say we have a fair match:

    * 100 games, to have some statistical relevance.
    * One move per day, so that being tired is no disadvantage (engine can ponder all day).
    * Human has access to endgame tablebases and opening databases, like the engine.
    * Human can make notes and has a software like Chess Position Trainer, which can min max, like the engine.

If the human is a GM with Elo 2700+ I predict 25 draws and 5 wins for the human. The engine wins 70 games.

It technically could happen but hasn’t so far.
