I went through a bunch of lessons when I re-emerged (not really; I just gave up on the website after a week because I wasn't really serious about chess). The "weekly lessons" added up because it was well over a year, so I went through a bunch of them in just a few days and learned a bit too much information for my noob brain to handle.
Ultimately it worked, though, seeing as I'm definitely a far better chess player than I was last year. I even made the quad digits today, though we'll have to see if that lasts.
should i do play, puzzles or lessons?
