Because something or some game is not in chess explorer does not mean it does not exist. I have played thousands of games not recorded in chess explorer.
This is a guess but I would guess chess explorer has less than 10% of all games played.
Chess explorer can be useful but when using chess explorer please know it does not always give the best moves or continuations.
True. When a trap as complicated as tarrasch's was found in this opening I would be very surprised if this was never found before.
Also, just because a trap isn't in game explorer doesn't mean it isn't (somewhat) known. Masters just don't fall into traps.
So, I'm not trying to take credit, I just think it's a nice trap that has a high success rate (against amateurs) in my personal experience.
