Chess Tactics for Beginners--how do I know if it is too easy?
Dan Heisman has several good articles and blog posts on studying tactics. See his blog posts on chess.com and his articles (the Novice Nook) on chesscafe.com.
He does sound as though he has a talent for the game, if he´s on 1200+ tactics trainer here at not yet six years old. Does he have a coach/teacher at the chess club? If so, he/she´s probably best placed to give you a qualified opinion.
Otherwise, it´s hard to judge - the rating systems on apps/programmes tend to vary widely. But he´s definitely got talent.
95% success rate is pretty good; It might be a bit easy for him. However, from the help file: "The exercises are arranged in five courses in order of increasing difficulty." So maybe the further he goes, the harder it gets?
I have a copy of the program, but I never really used it much before. After the thread was started, I decided to start going through it. I'm up to about 200; I think there are around 1300 problems. It might be days before I can get anywhere close to the end, especially if I get burned out and have to take extended breaks. They seem to already be getting a bit harder compared to the ones at the beginning. I'll let you know if they get harder still.
I suspect that the program does overrate you several hundred points.
The main disadvantage I noticed is that it tells you what kind of tactic you're looking for, so that makes it easier to spot.
Yeah, if you miss one or take too long, you get fewer points or even a penalty.
I'm in the draw section, too. Missed a few, darn it!
If you also want to experiment with a free tactics program, you could try YATT. It's a bit less kid friendly, but it might still work for him. It's not timed, and it doesn't track your success rate. The tactics set that comes with it is about 5500 problems, some easy, some hard.
