I was slaughtered today at ChessTempo. I meant to work on just a few, but I felt some mojo or something after lunch and I just kept plugging away. Like an addicted gambler, I kept thinking things would turn around, but they never did. I went from a relative high of 1855 a few days ago to 1764 today. I did over 100 problems today and I was nickled and dimed down bit by bit. My vision just wasn't there. Sometimes I saw it, others times I'd be completely stumped.
Game 18 was more on the Queen's Gambit. Again, Chernev emphasized the importance of c5. Black must dispute the center by pushing towards c5 and White must defend c5 at all costs. There is a lot of positional stuff going on. I kind of understand it, but there's no firm grasp for sure. There seem to be a lot of neuances that I would never get in a real game.
