Actually... you guys have got me thinking now. On my way into work I realized that I could probably get a recommendation from DS's chess mentor. He started playing serious chess a couple of months ago so I started taking him to a local chess club. The organizer has taken him under his wing and gives him free private lessons before the club meets. (Usually he's a paid coach.) So I think that leaves us with three options if using his grandmother is okay. I forget how many you need.
Luckily I did capture on video once something that I think would be appropriate to submit...
Thanks for the brainstorming...
