1. d4 d5 2. c4 c6 3. Nc3 Nf6 4. Nf3 e6 5. Bg5 h6 ({Black declines the
Botvinnik system} 5... dxc4 6. e4 b5 7. e5) 6. Bh4 ({A quiet alternative to
the text move is} 6. Bxf6 Qxf6) 6... Be7 ({And Black also doesn't go for the
gambit line} 6... dxc4 7. e4 g5 8. Bg3 b5 {which is considered very unclear.})
7. e3 {Now White has an easy play without any risk. Black's move c7-c6 isn't
very useful now as it limits Black's Bc8 even more than it is usually in the
Classical Queen's Gambit. Black usually tries to fulfil such plan: to capture
on c4 d5xc4 and then to play b7-b5, Bc8-b7 and finally c6-c5. White strives to
prevent it, of course.} O-O 8. Bd3 {White simply develops his bishop.} ({
Possible is also} 8. Rc1 {with idea to capture on c4 in one move, but after}
Nbd7 (8... dxc4 $6 9. Bxc4) {White has probably anything better than} 9. Bd3 {
