1. c2c4  1... e7e6  2. g1f3  2... d7d5  3. g2g3  3... g8f6  4. f1g2  4... f8e7  5. e1g1  5... e8g8  6. d2d4  6... f6e4 A rare line. Rapport is heading for the Dutch Stonewall. 7. d1c2  7... c7c6  8. b2b3  8... b8d7  9. c1b2  9... d8e8  10. b1c3  10... f7f5  11. e2e3  11... e7d6 This is one of the differences in comparison of the usual  Stonewall. The bishop gets to the optimal d6 square after losing a tempo.  Black can however argue that the white knight on f3 is not ideal neither  and that the closed character of the position would not lead to anything  hugely harmful because of this tempo. 12. c3e2  12... g7g5 A novelty, which  deprives the white knight of the f4 square.
