IM pfren, is it your opinion that the strongest human could beat the strongest computer at long time controls more than 50% of the time?
I assume they play computers regularly for training purposes, but of course the data regarding their performance vs computers isn't available to us ordinary folks.
Impossible to spot.
If there's a single good move, how do you know the player doesn't just know the technique/how to play the endgame? You don't.
End game I will just read about the specific situation and go over it by playing it a few times to see if it works and read about the technque.
