Chess, Computers and Humans

At one point in my life I thought it might be a good chess player. In the mid-80 collected and reviewed annotated games by Leontxo Garcia in El País -what big- and even I tried to make my first steps a little more seriously and played a federated year. Enough to realize that it would be better devoted to  write, but I always kept my love of a sport for years to continue sideways.

I did in those legendary duels between Karpov and Kasparov, but also with a nod to the passion that became part of my job: computer science. Expectantly read the news about the fighting between grandmasters and chess computers and cheated me over and over again thinking the man would always be higher than the machine. Absurd, as demonstrate a machine called Deep Blue the 11th of May 1997.

The beginning of the end

Leontxo Garcia wrote it better than anyone again in the country. In ” Man surrenders to the machine ” (curious, lack the tilde in the headline) this journalist recounted how Gari Kasparov ended up leaving the sixth game and losing by 3.5 to 2.5 against Deep Blue after an unexplainable mistake just initiated opening. IBM ride later much a tribute website as another to revisit the games that especially cool because web 1.0 is all.

These two factors have been fixed in the new Yoga 900, but this Lenovo engineers have not hesitated to slightly increase both the weight of the device which rises to 1.30 kg from 1.19 anterior- and thickness, reduced from 12.8 mm from Yoga Pro 3 to about 16 mm of this new model.

That makes the team is not exactly a “pen”, but still we have a good bet and a great balance of size, weight and performance. 900 Yoga design is similar to the previous model, with a magnesium alloy as the lead in the upper housing in which, yes, the brand “Yoga” appears more prominent than “Lenovo”. JBL speakers on either side of the team, as we saw offer excellent sound quality even when we put the notebook in tablet mode: a curious detail appears at the bottom.
