I must confess that I never really understood what he meant with that. 2. g2g3  2... g8f6  3. f1g2  3... c7c6  4. d2d4  4... e5e4 The other popular moves are 4...exd4 and 4...Bb4+. 5. d4d5 [%c_effect d5;square;d5;type;Interesting;persistent;true] Preventing Black from playing d7-d5. 5... f8b4  6. c1d2  6... b4d2 [%c_effect d2;square;d2;type;Inaccuracy;persistent;true] 7. d1d2  7... e8g8  8. b1c3  8... f8e8  9. e2e3 [%c_effect e3;square;e3;type;Inaccuracy;persistent;true] 9... d7d6  10. g1e2  10... c6c5 [%c_effect c5;square;c5;type;Inaccuracy;persistent;true]
