1. d2d4  1... g8f6  2. g1f3  2... d7d5  3. c1f4 The good, old London System. Innocent in appearance, dangerous in essence. One day, the chess world will recognize its true value. Until then, my job as a commentator is to criticize it every time it is played. 3... e7e6  4. e2e3  4... f8d6  5. b1d2  5... e8g8  6. c2c3  6... c7c5  7. f1d3  7... b7b6  8. f4d6 Other moves are possible: 8... d8d6  9. f3e5  9... c8a6 [%c_effect a6;square;a6;type;GreatFind;persistent;true] 10. d3c2 [%c_effect c2;square;c2;type;Interesting;persistent;true] An aggressive and double-edged move. White keeps the dangerous bishop on the board, pointing at Black's king. This, however, comes at a cost: Black's a6-bishop is also very powerful and hinders White's ability to castle kingside. 10... f6d7 [%c_effect d7;square;d7;type;Inaccuracy;persistent;true] Black decides to close the opponent's bishop diagonal with f7-f5, but this is not the best plan. 11. f2f4  11... f7f5  12. d1h5 The queen is not so useful on h5. 12... c5d4 The change in the pawn structure helps White. It's better to keep the tension and move the knight to c6 immediately. 13. e3d4  13... b8c6  14. e5d7  14... d6d7  15. d2f3 [%c_effect f3;square;f3;type;Inaccuracy;persistent;true] This gives Black a tactical opportunity to improve his bishop. 15... a8c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true] 16. a2a3  16... d7d6  17. g2g3 White now has a clear advantage. His pawn structure is better, and the pawn break on b4 (essentially Black's only plan) is very hard to achieve. Truth be told, it's also not so easy to break Black's solid position. 17... a6c4  18. e1f2  18... f8f6  19. f3e5  19... c4a6 The bishop going to c4 and coming back to a6 is proof that Sarana was having a hard time finding a plan. 20. a1d1  20... d6c7  21. e5c6  21... c7c6  22. h5f3  22... c6b5  23. d1b1  23... g8h8  24. h1e1
