Henry, thanks for the reply and settling my interest on that chess match (I always wondered about that, HAHA.) Unlike you, Rush, Hawaii Steve and others, I wasn't a participant on Curt Schmidt's Message Board. My interest (like most others these days) started with the films I watched in my youth. However, I'm more of a bookworm and truly enjoyed the novels best.
Amazingly though, while living in Hawaii for 16 years, my grandkids loved watching a Chan film every Saturday, which is what we did; often with Hawaii Steve there to accompany our dinner and a movie weekends. You probably know Steve gave a Charlie Chan walking tour, and when not "on duty" he and I walked the streets looking for spots in the films and books.
If you are interested I blog about Chan, Biggers, Hawaii & Ohio once a month at:

I'll be entering my 5th year with the blog this January. Happy Thanksgiving. Lou
