Chesstempo!
I used to do the tactics at the Chess Tactics Server, but it doesn't let you look at the board! I learned some tactics, but I practiced bad chess by doing something that looked promising from my dismal perspective and hoped for the best.
I'm hoping to have the discipline to sit on my hands! I may try it literally if I find myself playing to quickly again!
50 more points today!
My goal is to hit 2000. I figure 2000 tactics should be good enough for now and if I'm still around 1400 here, there's some other area where I really need help.
Perhaps by working through the Mammoth Book of Chess will do the trick, if not I still have a Purdy book that I think I can handle better this time.
1650 just in case you were wondering.
