Invincible is a wonderful book, but commentary (which is the reason you're buying it right?) is not for kyu players in my opinion.

Generally, no.

Most books on topics in go use pro games as examples, and provide commentary that way. So reading other go books often indirectly gives you commentary. Pro games are played at a very very high level, there's no way around it, so commentary on pro games tends to be inaccessible to weak players. Maybe some 5k-1k can get something out of it, but for ddk I think it's definitely a waste of time.

The KGS+ lectures aim at a mostly kyu player audience from what I can tell (though I don't subscribe to them), so they might be a good source of simplified commentary.

I'm not saying not to look at pro games, but I think the in depth analysis found in most commentaries is going to over the head of most kyu players most of the time.

I have had two different go instructors tell me to review pro games and imitate moves (i.e. good shape), even if I don't fully understand why. I have rejected this advice because I do not like to play moves without having any idea why. I also see moves criticized when when they the follow-up is poor because the person obviously didn't know why they made the move.

But, at a certain level (like mine) maybe this isn't such a terrible idea as long as you learn the "why" eventually. I'm still reluctant, though.
