Chess tactics explained
I wondered if the popularity of 'The queen's Gambit' would lead  to a brief infatuation with chess in the popular imagination. The fact I've seen about 3 chess related submissions on HN recently, where I don't recall ever seeing one before, suggests it does.I used to enjoy a game of chess back in the day, although I was never very good. And I always imagined myself playing chess with a remote opponent by post when I was a dusty old man [as featured in a few period dramas].It's a shame that the advent of the internet has simultaneously increased your chances of finding someone to play with remotely but, at the same time, [for me anyway] pretty much removed all inclination to do so, as I'd never be sure my opponent wasn't just putting the moves into a computer and playing whatever it told him to play.
