I often find myself calculating the same variations over and over and I think I'm using my time wrong.
Very old thread but since folks are still commenting I thought I'd chime in.
I would strongly endorse doing "Stoyko" exercises. Years ago I also felt the need to improve my calculation skills, and did hundreds of these. Essentially you take a complicated
tactical position, write out all of your thinking, and compare your solution to the answer. At first it is very hard and your thinking is messy, but you definitely get better over time.
A checklist can certainly help keep you focused, especially when you're first starting. The general process is:
1 identify candidate moves,
2 calculate each candidate,
3 evaluate the final position, and
4 choose the move with the best (or least bad) evaluation.
You could have checklists for each step, but that is likely overkill. You mentioned that you're repeating the same line over and over, which could mean that you are not doing a concrete evaluation of the final position in each line (step 3), or you might "think" you're missing resources for yourself or your opponent during line calculation (step 2).
It is more likely that you're stuck recalculating lines on step 2, and Stoyko will definitely help you there because by writing out all of your thinking, you can see exactly what you are doing wrong. There is a certain logic inherent to forced play, and you CAN identify your mistakes and improve.
For example, are you missing defensive replies by your opponent? Let's say you see a check and that the king has two moves, and you calculate each one...but doh, you didn't "see" that he can also block. Here's the important part...did you LOOK for his blocks but not see it? Or did you not even think to look? Very different problems, but both can be easily fixed by being more diligent.
Also, you can get stuck on the same line if you are absolutely convinced that you have something...a tactic, or mate...something that will win you the brilliancy prize if you can only find the right move. This is MUCH more interesting. In a real game, you have to be practical and make yourself move if you can't find the solution in a certain amount of time. In a practice position, this is the kind of thing puzzles are made out of and you can just drill the kinds of tactical shots you find yourself missing (are you missing quiet moves, backwards moves, do you have blindspots for discoveries, etc).
So bottom line is to use Stoyko exercises to diagnose your calculation problems...checklists for certain steps can definitely be useful.
