If White continues from the diagram with 6.Bd3, 6...dxc4 leads to the Meran Variation, which gets its name from the game Grünfeld – Rubinstein in the 1924 Meran Tournament. Black gives up the strong point on d5 in the centre, to develop his queenside as quickly as possible with moves like...b5, ...a6, ...Bb7 and ...c5. The basic position arises after 6.Bd3 dxc4 with the move order 7.Bxc4 b5 8.Bd3 a6 (8...Bb7 is an alternative) 9.e4 c5=> More products: Semi-Slav Defence
The material divides as follows:
1a) The Anti-Moscow Gambit with 6.Bh4 leads to doubled-edged play because Black will try to keep his extra pawn after 6…dxc4 7.e4 g5 8.Bg3 b5 etc.
1b) The Moscow Variation with 6.Bxf6 leads to an immediate imbalance but White’s attacking chances contain more venom than you might believe at first!
2) 5…dxc4 T he Botvinnik Variation with 5…dxc4 is Black’s sharpest option. It cannot get any crazier!
3) 5…Nbd7 T he Cambridge-Springs Variation with 5…Nbd7 is Black’s most solid option, but it still leads to a strategically and tactically complicated middlegame.
