Here's the thing...
I played chess as a teenager. I read books. There were no computers back then. I studied, practiced...and I would usually win (this was casual, not tournament, so I'm not bragging).
Today, after a 40 year vacation (mostly) from chess, I am a better play than the young fellow I was.
This is because for the last two years, I have been studying/practicing about two hours per day (and I know that that isn't so much by those who are far better at chess than I am).
I didn't have the time to do this back then. Also, I am older and wiser in ways that give me some advantages.
If some of you guys in your 30ies or 40ies think you are getting dim witted...maybe you are right, in your case.
Hell, some people are so dim witted that they should never have taken up chess in the first place. (lol)
Now that I've just insulted more than half the people here...I gotta run.
Holy cow, folks! We just heard from a superior being! He/she (it?) must be right!
