marshall defense is 1.d4,Nf6 2.c4,d5 3.cxd5,Nxd5 4.e4 It is clear that white has the advantage due to pawn centre and open lines for developement. But whenever I play these position, opponent puts a lot of pressure and I lose. How should I play these kinds of position with hanging pawn centres?
White should play more slowly to keep control of the position, eg 1. d4 d5 2. c4 Nf6 3. cxd5 Nxd5 4. Nf3! g6!? (4... Bf5 5. Nbd2!) 5. e4 Nb6 6. h3! Bg7 7. Nc3 0-0 8. Be2 with a very nice advantage.
