Chess, like love, is a many-splendored thing. We can enjoy it on so many different levels. “Serious” chess, skittles, blitz, correspondence, problems, history, variants, and more. We play it, watch it, read about it, dream about it, argue about it. One aspect that seems to attract many is the naming of variations. We can always find some good arguments there.
A reader put me onto a site which does a good job at outlining BDG variations. The variations are named, provided a diagram, and Rybka evaluations of the four leading responses. (This is interesting, if of limited utility). Here’s an example:
Take a look at the site here. The proprietor is Knut Jarle Hjørnevik from Norway, a fairly strong player with a Fide rating of 2038, who has been playing the BDG for a year or so now. You might quibble with a name or two, but that’s part of the fun.
