First Tournament and a series of loses.


It's not that the kids are talented, it's that they are kids. They improve more quickly than older players. Most of the kids I train with improve faster than I do, despite the fact that they spend a quarter of the time, study and practice less intensely, and train far less systematically (and without coaches).
Improving at tournament chess, especially if you are 25+ years old, is very difficult. Most players who play their entire adult life either exhibit no rating improvement or well less than 400 points. I've trained both older adults and kids, and my youths tend to gain 200-800 points in 6-18 months, whereas it's taken some adult-learner friends 10 years to gain 100 (and at a relatively low rating level). It's a grind. You've got to want it, and you've got to be passionate to improve. There is definitely no quick fix. Very likely, you'll play many thousands of games per year, study hundreds of games, and see no apparent definitive rating climb, unless you keep at it for a significant duration, and then you'll see an upward rating trend. Keep this in mind, if you are improving, you'll score poorly, too, because you'll be playing stronger players basically every other round. I score between 43%-44%, so I don't even win half of my Federation OTB games --not by a long shot.
