I just checked this out. I couldn't find a link to a 1$ try, but got a demo video sent, and I must say...
It was really good!!!
I live in Japan and watch the NHK go TV programs every week. These are very informative, but sometimes lack the depth I seek because they cover an entire game over 1.5 hours. The commentator will often take a look at why a professional played something, but only offer 2 or so variations.
The video sent, on the other hand offered a ton of variations in a short time. I knew some, but feel that it really helped add to the knowledge I have. I feel more confident playing them now because I understand the slight differences related to the variations.
Also, I think a lot of westerners, especially kyu level players, tend to play a more "Japanese" style of go because most of the theory available in English is from Japanese players.
So these videos are perfect to get a look at more modern go with a slightly different style.
I wish they had something like this in Japanese because 7$ is a really bargain imo.
I think I might have to learn Korean
