More important is your percentage rating. Also because of the timer, and not knowing what tactic you are looking for represents more board like circumstances, and makes it much harder than the actual rating of the problem. If you ever checked any of the games many of those tactics come from are from master, or GM games. They are not necessarily easy to find the right answer too.
Keep doing them, that is the only way you will master them. I grit my teeth on some of them as well. Lol, but overall they will help you. Its like doing pushups with your mind. Good luck.
I've done nearly 900 problems over the last 6 weeks and I am not seeing much improvement in my tactics rating or standard live chess rating (almost all my live chess games are 30|0 and I have played over 100 rated games). My tactics rating seems to be consistently lower than my standard live chess rating which I find a little odd (~100 points lower).
I also notice that many comments posted with the problems in the tactics trainer are by people with significantly higher ratings. Why are they doing problems in the 1100 to 1200 range when their ratings are 1400 to 1800 in some cases.
Can anyone help me with techniques for improving my performance with the tactics trainer? Obviously brute force in terms of number of problems attempted isn't getting it done.
