The biggest reason that I don't go through pro games, is that I think they're on a level that I can't really understand without commentary. If I try to learn how to use pro moves, in most cases my opponent will go to the complicated but suboptimal resistance. If I then mess up that, it's rather sad for me.

Lol, that video always makes me laugh but I wonder if it isn't the exception that proves the rule. I mean, even though it's literally the worst move he could possibly have played it's also pretty obvious what he hoped to gain from it, and I think that's the key point. Whether a move is good or bad there's always a reason it was played, so if you can't see what that is there must be a gap in your understanding.

It reminds me of when I used to do kendo and our teacher talked to us about how your supposed to try and feel out your opponent when your swords are touching. Advanced practitioners learn to recognise momentary lapses in concentration by how the opponent responds to this contact, but they also learn to fake these lapses which can result in the apparent foolishness of one player impaling themselves on the other's sword. Any beginner can see this is a bad idea, but learning to be tricked in to doing it is actually what they need to do to move forwards.

I have certainly heard that the most dangerous swordsmen (or women) are absolute beginners, because they can't be expected to react in a standard way and can easily kill you in the process. Once they gain some skill, they realize how easy it is to die or be taken advantage of and suddenly they won't commit to all of the things they would beforehand.

I think in go, you see this sort of phenomenon in handicap games to some extent. Often, white is put in a position where they don't want to play a move because they know it doesn't work, but at the same time, their opponent has no idea how to handle it and will quite likely do so very incorrectly.
