If I am not mistaken, an episode by this title aired July 25. The guest star was David Straitharn, but I see William Atherton listed as the guest star here on IMDb. If I am right, and this episode was the one featuring Straitharn, I will say it was a fun episode very much written in a COLOMBO vein. Monk matches wits with an incredibly egotistical grand chess master whose IQ is higher than Einstein's. While Straitharn is playing chess, live on TV in Vancouver, his wife dies by means unknown (actually, Monk immediately guesses how, but the evidence is missing). We're sure we know Straitharn is the murderer, and so does does Monk. But Monk has a tough time pinning the crime on him. It is a cat and mouse game to the very end, and pretty serious. The final shot is priceless.
