I think the 'applied concept video' is a great idea. Lately I bearly even click on the videos tab any more because its the same thing over and over live sweats and hand history reviews. They can be good at times to see how the instructor goes about dealing with certain situations and how he navigates through the tournament but most of the time its bits of information all muddled up and you come away from it not learning much at all. Plus the videos are usually mid to high stakes making them less relevant when you play small stakes(which is most people, judgeing from what I see in the forums). A targeted video that explains a concept through theory and examples is by far a better way to learn imo. You can then say to yourself Ok I need to work on my push/fold game or I need to learn about donk betting or whatever and you'd have a list of video series that teach that specific concept. Then when you watch the video you know exactly what the goal is and what you should have learnt by the end of it.

Andrew Brokos's theory videos have been excellent. He starts off by stating the goal of the video so we know what we're goin to be learning and then works through them with theory and examples while also pausing in spots so the viewer can interact. Really the only reason I'm clicking on the videos tab is to see if he has any new ones out!!

My own personal wish list would be videos about 

1) Donk betting

2) Battle of the blinds, from stealing them to protecting them

3) Something on flop play(good and bad spots to c-bet and check raise bluffing) etc

Foucault has said that he is nearly finished a theory video series that will be up soon, so that will be well worth watching. Its a start!

 1. How to do a hand history review.

I don't know where to start when reviewing a session that might include 20+ tourneys. When does a couple of mistakes in hands turn into a leak, how do you know? It could also include advice for getting the mind in gear before you start tournaments, do pros review hands before they play, do they dive right in, do they have goals for their sessions etc.

2. Facing 3bets OOP

The thought process that goes into the decision to call, fold or 4bet

I think your post is pretty clear, bit long winded but I think people get what you mean. (BTW your english is fine, I only recently started posting here and I just realised how bad I write and english is my native language!! so don't feel too bad). I like the idea, I feel my late game is prob my weakist so would love to see a vid addressing these issues. 

Answer to your question- Do you regulary 3bet fold at 20bb? I feel like you should be 3bet shoving at 20 bigs. With regards to raise/folding at 12bbs, I've been experimenting with min raising as a bluff with this stack size as people will usually play pretty honest when you min raise this stack, i.e shove on you when they have you beat and sometimes fold a hand they would normally call a shove with because the line looks so strong. Could be wrong mathematically but I've had some sucess with it lately.
