Just shows the human brain is still not to be underestimated.Eelco de Groot wrote:Thanks a lot Martin and Louis! Wow, even the TCEC computer has stopped playing games and the TCEC rating lists will now be delayed. The Washington Post can't publish a new article on Houdini because of this, and goes broke. This starts the final collapse of the US economy, looting and arson in the big cities in the North, China invades Taiwan and Japan in the following turmoil, to protect vital interests in their influence zone, uprising in Tibet and Mongolia ensues, all this because of a single chess position. It better be worth it...Martin Thoresen wrote:Here's 1 hour and 42 minutes with Houdini on the TCEC computer, 8 GB hash with Large Pages:
