I am a patzer.
I see chess and football very similar here. I see a blunder much like a fumble. In chess, instead of losing the ball, you lose a piece and a tempo. For a very weak player against a strong player, the blunders seem more abundant. Of course the stronger player is helping to FORCE the blunder/fumble. On the other side, occasionally, a stonger player blunders/fumbles to a weaker player. Giving chess the Any Given Sunday feel. For the most part though, equal players games are determined by who makes the least mistakes/fumbles. The stronger players can really absorb these blunders against a weaker player and still win. On the other side, once a weaker player loses a minor piece against a strong player. Not much chance to recover. That is just how I see it. If I did not blunder, my rating would be much higher than it is. Practice, practice, practice.
