This is a new gambit I created against the Vienna ! called the Anti-Vienna Gambit / AV Gambit !
https://www.chess.com/game/live/32668766295 Please check It out. U can see it starts out with birds then into a fianchetto. They usually respond with d4 when u play f4 so after u fianchetto the idea is to strike back in the center quickly with c4 d4 of e4 usually the main problem is the dark-squared bishop. . I shall call it the slingshot variation to the king's fienchetto because u slingshot a pawn into the center
Franco-Slav: Diemer Gambit, Center-Gruenfeld-Kings Indian-Fianchetto Blackmar-Diemer Gambit 4.Qa4
also able to be reached via the French: Diemer-Duhm Gambit as shown in the diagram
Hmmm so whats the point of the opening
To either force Black to transpose into a French Defence: Exchange, Monte-Carlo Variation which is just miserable for Black after c5! as his DSB is locked in jail with his LSB to be limited in the future and then white to enjoy a happy game or to force Black to accept the pawn gambit and allow white to actively put pressure on the pawn while developing with ease and eventually regaining the pawn and then opening the d-file and the g and h files against Black because as shown above 4.Qa4 Nf6 5.exd5 exd5 is forced as Qa4 pins the c6 pawn to the king
Rubinstein, Fischer, Karpov, Kramnik, Carlsen, all have/had almost flawless technique. But the latter 4 learned the stuff from Akiba.
Just to clarify , What's the point you're making @pfren ?
Italian Game: Two Knights Berlin Wall Defence, Berlin Wall Endgame
There are no previous games in the database after 4.Bb5
After 11.Nc3 the position transposes to a semblance of a Berlin Wall Defence / Berlin Endgame with only 1 move 11.h6 in the database
After 15.g4 there are no moves in the database but the position is in a semblance of a Berlin Wall Defence / Berlin Endgame
The funny thing is for post #61 is that if you try inserting the moves in the database with the normal Berlin Wall move order then it follows to a game between Lidia Tomnickova as White and Maria Severina as Black played on the 18th of April 2014.
Meaning that after just 15.Ne7 16.h3 we're still in database territory!
pretty bad for @guanlinzhou, they are kinda weird
