Chess is a game of endless possibilities that does not need a language. If you come to a new city or country a Chess Club will always be a welcoming place, even if you know nobody there.
You can teach kids something that will accompany them for their whole life, if they want it so. As with all teaching, seeing them get it is rewarding.
As a player the 5th place in the NZ Blitz Champs in 2008. As a coach taking a Junior team to two German Championships and taking my daughter to the World Cadet Championships in 2017.
Chess teaches kids to plan ahead and the consequences of not doing so properly. Chess improves their ability to focus on the task (position) ahead.
