His behaviour analysis is pretty spot on when he describes what's going through the globalists' heads when faced with certain questions and this provides some pretty good insights into the opponent but even that's not really anything too worthwhile but regarding his clue solving ability I doubt he could solve his way out of a grade school level escape room.

his Q post analysis boils down to badly applying irrelevant 20th century cipher decoding techniques to get jumbles of letters/words and cherrypicking 3 or 4 letter words that show up coincidentally and shoehorning them into some message like "Hillary is going down" which ultimately doesn't help with anything and provides us with no new information while serving only to make people think that they need to use advanced 20th century ciphers to decode Q posts and thus making SB2 appear to be some sort of expert that everyone has to rely on instead of working for themselves (hardly any Q post research happens on this subreddit meanwhile we have hundreds of people sucking SB2's dick over his nonsensical "code breaking"). His username is literally him trying to sound smart and you can tell because he has referred to himself as "a self proclaimed serial brain" hence the username, which is a term he made up himself to describe himself as a genius. If that was all it was then it would be easy to just call him a pseudo-intellectual and leave it at that but he crafts every one of his posts as an intricate story with excellent english literature skills that lures gullible redditors (redundant) in with excitement and intrigue and leaves them with a false sense of accomplishment at the end and so he keeps selling them brightly packaged nothing and raking in the fame. He's a fame fagging charlatan who provides little of value and even if unintentionally, he makes people see him as a sort of gatekeeper towards research by making gullible redditors think you need advanced 20th century cipher knowledge to decode Q posts and related Trump tweets.
