Black responses
Why playing double queen pawn opening
  • Essentially, black trying to gain same advantage like White by moving pawn in front of queen.
  • Also, by playing 1...d5 Black trying to discourage White to play 2.e4.
  • Because if White insisted playing 2.e4, then Black capture e pawn with 2...dxe4 gaining free pawn.
  • The result of 2...dxe4 lead to Blackmar-Diemer Gambit position.
  • Blackmar-Diemer Gambit is gambit move, in which White offer free pawn for quick development and attacking chance.
  • Blackmar-Diemer Gambit is considered too risky if played in professional level.
  • But, it can be used as surprise weapon against unprepared opponent.
1...Nf6 (A45: Indian Defense)
is indian defense good?

1...c5 (A43: Old Benoni Defense)
Reason of playing Old Benoni Defense
  • Black didn't want White to establish pawn in the center, So Black by use c pawn as decoy.
  • Decoy is chess tactic which lure opponent pieces into particular square, in order to gain better position.
  • By using c pawn as decoy, Black trying to lure White d pawn into c file by playing 2.dxc5.
  • If succeeded, then black play 2...e5 to reveal discovered attack by dark squared Bishop against White Pawn (in order to regain material balance).
  • Discovered attack is chess tactic which reveal a previously blocked attack by moving by another pieces.
  • The result position is better for Black.
1...e5?! (A40: Englund Gambit)
  • Black trying to open the center by offering free pawn to white.
  • This move considered dubious, so it wise not play this move, even though there is trap and have a chance to regain material balance.
  • If White know how to response the trap, then the result of Englund Gambit favorable for White.
  • The trap start at 5...Qxb2, the move order leading to Englund Gambit Trap are:
  • White logical continuation facing this gambit is to capture e5 pawn by playing 2.dxe5.
  • Then Black continuation is playing 2...Nc6 attacking White pawn.
  • The logical response for White is to protect the attacked pawn with 3.Nf3.
  • Black trying to add pressure to White by combining queen and knight to attack pawn.
  • White can choose between attacking the queen (4.Bg5) or protect the pawn (4.Bf4)
  • Black check White King by playing 4...Qb4+.
  • The logical response is to protect Black King by blocking the attack with Bishop (5.Bd2) while at the same time attack White Queen.
  • Black then play 5...Qxb2 regain material balance and threaten to capture Black Rook on a1.
  • It very tempting to attack Black Queen by playing 6.Bc3, but this move make White fall for Black trap.
  • The correct response to this move is 6.Nc3.
  • The continuation after 6.Nc3 favorable for White.
