I don't see the problem. I was soundly beaten by a kid OTB last year, and I don't even think he'll become a master some day. At my level it could happen every day. We are playing chess, not boxing.
When a kid supposedly beats you....

In Canada in the U12 group there are two masters.
In the U10 the top is 2140 and the next three are A class. Even better, the top 5 are from only two cities, so it is possible that as an A class player you may very well face only kids in an OTB tournament.
On the upside these kids are the knowns. We have a parallel scholastic rating system where a kid might play active tournaments every month. A kid playing in the lower classes could easily be under rated by 200 points or more on the national scale before he gets to an 'adult' tournament.
Adults are easier.

How does a kid "supposedly" beat you? He either does or he doesn't.
I don't like to lose to a kid either. Supposedly my experience should count for something. But face it - kids do have a biological advantage. Their brains are more malleable and can grasp concepts quickly if properly taught.
That's why I think Scholastic chess tends to do more harm than good. Most kids aren't properly taught, think they know how to play the game, and then drop out too soon. Those who leave the scholastic system, seek experienced training, usually end up being able to hand you your head on a platter.

I once got crushed by this seven year old who could barely see over the board. Who did that kid think he was?
Oh, right...it was this kid:

we all know, its not what you think someone can do that you look out for... its what they actually can do. if you think computer chess is straight your a fool. here being it is wide open and anyone can have multiple accounts even, its time to address the real issue. it sometimes takes a few minutes to find those reall good moves. but when every single move made is so perfect and seems to screw you so bad, and theres no time taken to even think about the move...... your playing a guy staring at a program. its good to see so many give credit to people, but i dont. real chess is played on a board. when a real game gets played here we can talk.
