so they be lazy because they can. i mean chess is literally a game about winning how do you think the best became the best?
lol, un-sarcastic answer... by losing 1000s of games.
And that's a quote from Karpov "to become a great chess player you must lose 1000s of games."
(Of course in those days there was no online trash. He meant 1000s of serious OTB tournament games)
ive never understood [why playing for a draw at the top level is popular]
Because top players are professionals... their literal job is to make money by winning tournaments.
4 or 5 wins out of 9 is enough to win pretty much any tournament (as long as you draw the rest).
It's also very hard to win with black... and if white is determined to make a draw, it can be almost impossible for black to win.
Decisive games are rare because, either one player has to screw up, or both players have to agree to allow the position to become doubled edged enough that someone might lose.
