Playing room on the eight round

Last week I had the opportunity to make a break on my daily activities to attend the Mexico's 63rd Chess Open Championship in the city of Leon, Guanajuato. This event officially sets my return to chess competition after many years of absence, since I retired for a long time to focus on other activities.

Even when it's well known nowadays the power of chess engines has left behind the human playing abilities by far, recently it appeared on the web a chess diagram that gets the attention from we all curious and chess players. The diagram is a puzzle proposed by the Penrose Institute and it's a clever way to prove how big is still the gap between computers (even despite of its greatest capacity to calculate variations) and human mind.
