so i remeber watching this anime in Japan were this old guy is playing a proffesional chess match. while in a nearby hotel room, some chick in a hotel room is helping him cheat or something. the old guy then looses and his opponent(dective) goes outside and kisses his busty blond girlfriend. the end credits involve this kid riding in the back of a truck. does this ring any bells here? i can't read Jap so i don't know the title.
