I'm not sure why people are hiding their comments.
When a game goes to the endgame, I think it's interesting to look at the opening position and see if it looks at all like the endgame position or of territories have been exchanged. It's also interested to see which stones are saved vs. sacrificied. Take a look at the position at move 53:
Usually Cho likes territory very much, but here we see black occupying three corners. Here, I think what is interesting is the exchanges made by black's marked stones. The ones on the upper side have already been sacrificed, and the three in the center are very short of liberties. I think many beginners would have tried to save both sets of stones early. (About 50 moves later, black does eventually connect the center stones, but they become dame points.)
For me, it is a little hard to appreciate what black has gained by this forcing. Maybe we can talk about whether the wedge at 37 is somehow made more powerful by that. If black had played this wedge earlier, for example, here, how would it have gone?
Anyway, I think I'm missing some concepts that would help me appreciate moves 29-37 more, so maybe stronger players can help. Maybe black's view is that this is all just kikasare for white, so, you know, whatever. But it would hard for me to emulate what black is doing there. I don't like to force like that without a clear idea of what's being gained. I guess if white has to play too many slow moves to capture the forcing stones (i.e. they are bait) that's one thing, but the value is hard to judge.
Let's start with that. I'll have other questions later...
is a common lighter shape, as is the gozumi at 
to be severe. I might play these moves, but the question is the timing and how it relates to the wedge at
