I’ve been working around how to fight my recent ratings drop. For some reason, I was doing tremendously well on PlayChess while working on my second set of problems. I went effortlessly with an eight win streak. I was easily able to compete with players rated 500 points higher than me while I was working on those problems. Now, I’m nothing but a nuisance to them again.
My conclusion is that the second set of problems in particular is no doubt the best I’ve come across for raw tactics training. To see if my tactics vision was getting dull again, I just did a circle through those 120 problems in the second set. I wasn’t surprised to find that it was taking me abnormally longer to finish them (although I finished with a score of 91%). When I say abnormally long, I mean ten seconds or longer. This is unacceptable. From now on, I will always do one circle through them before I move on to my main problem set. This will not only serve as a warm-up, which I also think is very important, but it will keep my tactics vision sharp!
UPDATE: After doing warm-ups with the second set, I am back (for the moment at least) to constantly winning again.
