Playing the Queen's Gambit by Lars Schandorff
The power of the Queen's Gambit is beyond question, even though it allows some serious defences - the Slav and Semi-Slav are favoured by the elite, Kasparov was playing the Queen's Gambit Accepted until he retired, and the Queen's Gambit Declined has been trusted for a century.
The principled way for White to build a repertoire after 1.d4 d5 2.c4 is to play the critical main lines. Take as much space as possible – no compromises. That is Lars Standoff’s attitude and so his choice is clear:
5.Bg5 against the Semi-Slav
6.Ne5 versus the 5...Bf5 main line Slav
3.e4 against the Queen's Gambit Accepted
The Exchange Variation versus the Queen's Gambit Declined
5.c5 against the 4...a6-Slav
The Tarrasch, Chigorin, Albin and all minor lines are also met with the same vigour - this is a complete White repertoire after 1.d4 d5 2.c4.
