1. c2c4  1... c7c5  2. b1c3  2... b8c6  3. e2e3  3... g8f6  4. d2d4  4... d7d5  5. g1f3  5... e7e6  6. a2a3 White decides not to resolve the central tension and makes a waiting move. This is the most-played move in this position. 6... a7a6 Black follows the same strategy. 7. d4c5  7... f8c5  8. b2b4 Giving meaning to the pawn on a3. 8... c5e7 It's difficult to say which of the three bishop moves (to e7, d6, or a7) is the most accurate. The move played is the least popular of the three. 9. c1b2  9... e8g8  10. d1c2  10... d8b6 [%c_effect b6;square;b6;type;Mistake;persistent;true] A strange move that allows White to achieve an advantage in different ways. 11. f1e2 Not the most accurate. 11... d5c4  12. e2c4  12... f6g4 [%c_effect g4;square;g4;type;Mistake;persistent;true] Taking the knight to e5 is a typical idea, but here it doesn't reach its final destination and simply gets out of play. 13. c3a4
