1. c2c4 This is clearly the best first move available for White, with due respect to Fischer's 1.e4 \"best by test\" fans. But maybe I'm a little biased. 1... e7e5 Once my friend GM Ivan Morovic told me that against 1.c4 Black's only possible moves are either 1...e5 or 1...c5. 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] 11. h2h3 [%c_effect h3;square;h3;type;GreatFind;persistent;true] White has a simple plan: g4-Ng3 and take the central pawn. 11... b8d7  12. d2c2 Black desperately needs to create some counterplay and it seems that a timely …b7-b5 is the way to do it.
