Nge2 d5 6. a3 Bxc3+ 7. Nxc3 b6 8. b4 c5 {It often happens in the Nimzo Indian that Black has to concede the Bishop pair to his opponent. In return he usually has the (temporary) control of the crucial square e4, and so can give a half-closed character to the position. In the present game, Black lacks this compensation, and this is why White can rapidly go over to the attack} 9. dxc5 bxc5 10. cxd5 (10. bxc5 Ba6 11. Nb5 Ne4) 10... cxb4 $2 (10... Nxd5 $2 11.
