whats the best resource to learn abour effects of this nature?
There are no single best resources.
I perform all three of those effects listed, and the fact is that each of those three effects is a culmination of half a dozen different sources and methods each. Even when using, say, Derren Brown's psychological forces, principles from Banachek's Psychological Subtleties 2 come into play. But I would never be where I am with them had I not researched guys like Hilford. So there are some sources for that.
The Berglas Effect and The Open Prediction are both legendary effects with storied histories. A little research on either should give you some nice ideas - obviously, first thing to do would be to read about Berglas, and read about Marlo (NB: Not as in, reading the method, but read about the effect). And go from there.
In my opinion, the best way to get the most out of these effects is to do a lot of research, find every source you can on it - and work out your own version of the effect with what you have. When you hit the right path, when you discover your own path through the maze of authors of ACAAN effects, and Open Prediction effects, then you're most likely to be ready for them, and to make the most of them.
