Ofcourse I can't say what a correct opening is. What I can say though, is that if bots are onto something with their strange openings, at this point it's by accident. They really do underestimate the chances of an invader. That goes for moyo parachute invasions as well as corner invasions. I think

When building a joseki database, there is a caveat which may not be obvious to kyu-level players: Some joseki sequences depend upon ladder relationships. When the ladder succeeds, the joseki move may be brilliant. When the ladder fails, the same sequence leads to disaster. Smart opponents
