You completely miss the point, loudmouth.

The human had no reason to play for a draw in this game.
He got an excellent position and should have played for the win _without_ taking
any risks. It is well known that computers generally do not play this type of
positions well and Hydra is no exception.

You prove absolutely nothing. This wasn´t a correspondence game,
it was an OTB game and the human once again failed completely after he
unnecessarily opened the position.
