Is he a competitive personality? Not really. Winning is not his big motivator. I'd hate to see it go that direction.
I don't think being competitive (or not) should be seen as a flaw. The business world often wants people who have demonstrated a degree of competitiveness. Lots of good junior chess players become financial traders (to address ColinsMum's comment about transferable skills).
I want my children to be good sports. The other day, when my son reported to the tournament director that he had "creamed" his opponent, I told him to simply say "I won" in the future. But I also want them to want to win, whether it's at chess, physical sports, or talent search tests
and to prepare accordingly.
A 5yo boy may cry if he loses. A benefit of a chess or other tournament is to toughen him up, although that could certainly wait for a few years.
