THE site for Tsume Go study, with well over 2000 problems. You need a Java enabled browser to use it. They also have a time trial where you have 4 misses for problems, graded in difficulty from 30 kyu to 7 dan. --TimBrent
Reuven - I link to problems, there using (And btw, Not yet 2000 ^^* - Only the active once are counted. And Adum "fixed" it - Now u get another "life" every certain amount of problems..) Scartol: Am I the only one who finds the general difficulty rating system (Easy, Medium, Difficult) too vague? Easy seems to cover 30k-20k, and as a 9k, I can't even begin to follow most of the Difficult problems; which leads me to suspect that Medium covers 20k-5k or so. Quite a range! Maybe we could have a Low Medium and High Medium rating?
HolIgor: It seems to me that the problems are rated by the ratio of successful solutions there. A problem may change the level from hard to easy in a matter of hours as it is solved by more and more people. As the most of the solvers are of low kyu - dan level, all problems of 5 kyu level and below tend to become "easy" with time. I think one can ask adum to introduce new levels of difficulty. I think that now the grading is just for me (1k IGS). For me easy problems are easy, medium are medium and hard are hard. adum seems to be of the same level.
unkx80: Instead of using "easy", "medium", "hard" to see the difficulty of the problem, one can see the two numbers x/y instead. From Benjamin Geiger: What's stopping goproblems.com from entering some sort of partnership with a Go server? That way, when you log into goproblems.com, it could present problems of appropriate difficulty. More importantly, it could combine the success ratio with your rank and calculate based on that? (For example, if most of the visitors are 5k-2d, the success ratios given aren't going to be very helpful for a 25k. However, if it could determine how successful other 28k-22k players have been...) uxs: That would probably work, but I'm not sure if that is even necessary. Just having an account system on goproblems where information on the problems you solved is kept and used for balancing would probably work too. Reuven -
I'd like to ask if it's a good idea, to "systematically" copy problems from here to Opinion are more than welcome.. (Any idea how to make a poll?) This is a copy of the living page "goproblems.com" at Sensei's Library. ![]() |
