@ PDB - If you have a chance, would you post the above shot from your laserdisc? It's just after the title appears but before Discovery enters frame left. Thanks!

Chess anyone? Hope you like it ... 'cause Stanley Kubrick was playing chess through his films (and he was no patzer).

New York Review blog 2010/04/05 - Playing Chess With Kubrick
Which brings us to the microcosmic chess match in 2001. The Chess webpage 2001: A Chess Space Odyssey is a semi-interactive chess game of Roesch vs Schlage (Hamburg, 1910) ... I mean ... Poole vs HAL9000 (space, 2001+) ..

My previous 2001 webpage-recommendation's author surmised that HAL made a mistake in it's chess game, deliberately, to test Poole. This new recommendation is an in-depth critique of 2001 tempered by Kubrick's other films and thematic patterns notable in his works.
This article has teeth, lots of pages, and lots of pictures (I love it!). So put on a pot of coffee, pour yourselves a first cup, and, as Dr. Morbius might phrase it, prepare your minds for a new scale of values on Stanley Kubrick's 2001: A Space Odyssey ..

"Are you one of the league who find Kubrick's cinema fascinating and wonderful but are also confused by seeming peculiarities? Are you certain those often under-the-radar-over-the-head weirdnesses must mean something? Or maybe you're just curious? Well, I am the person who "discovered" the open door opposite Room 237 (and a lot more besides) so if you're looking for Kubrick high strangeness then you've come to the right place. But if I delve into the high strangeness, the oddities are simply a component part of analyzing the themes and ideas that Kubrick carries from film to film."
