A good part of answering 1 d4 with 1...d5 is that you know exactly what will happen next. You know your opponent is almost certain to lead the game into a Queen's Gambit.
That's also the bad part.
The Queen's Gambit, whether accepted or declined, is one of the warhorses of the openings. Others, even the Ruy Lopez as the favored form of 1 e4 e5 , may fade in and out of fashion. But the Queen's Gambit remains an institution. The main reason there are fewer Q.G.D's today than in the 1930's is that today more defenders are reluctant to defend, and can avoid the issue entirely by playing 1...Nf6.
To ease the burden of declining the gambit, some of the greatest masters of the past have contributed their ideas. Siegbert Tarrasch recommended attacking the center with...c7-c5 . Jose Capablanca recommended (after 1 d4 d5 2 c4 e6 3 Nc3 Nf6 4 Bg5 Be7 ) an eventual exchange of minor pieces with...dxc4 and...Nd5.
And Emanuel Lasker had another thought. Like Capablanca, he wanted to exchange two pairs of minor pieces to ease Black's constriction. But the German's manner was different: he wanted Black to play...Ne4!?
After introducing the idea in the 1890's, Lasker adopted it irregularly over the years but with generally good results. It was a memorable success in the 1907 Lasker-Marshall match, the last world championship match held entirely on Americal soil. Lasker scored 2 1/2 - 1/2 with Black, as he easily repulsed the American's questionable middlegame attacks.
