1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. d2d3  4... g8f6  5. c1g5 The modern treatment of the position. 5... h7h6  6. g5h4  6... c5e7 This is the reason why the Bc1-g5 idea was considered premature in the past. With the pin broken, it is not very obvious what the white bishop is doing on the h4-d8 diagonal. 7. h4g3  7... d7d6  8. a2a4  8... e8g8  9. h2h3  9... a7a5 [%c_effect a5;square;a5;type;Interesting;persistent;true] Apparently, this move will be seen more and more often in any Italian game. 10. e1g1  10... c8e6 While in his previous match Anand avoided the doubling of his pawns, he is now ready to do so with the white bishop standing offside. 11. c4e6  11... f7e6  12. c2c3  12... d8d7  13. b1d2  13... f8f7  14. d2c4 [%c_effect c4;square;c4;type;Interesting;persistent;true] A new and interesting idea. 14... b7b6 Prophylaxis against the maneuver Qd1-b3. 15. g3e5 [%cal dg3e5][%c_arrow g3e5;keyPressed;none;from;g3;opacity;0.8;to;e5;persistent;false][%c_highlight e5;keyPressed;none;opacity;0.8;square;e5;persistent;false] This is Santos' idea. In the arising imbalanced position, everything will depend on the mobility of the white pawns. 15... d6e5  16. c4e5  16... c6e5  17. f3e5  17... d7e8  18. e5f7  18... e8f7  19. d1e2  19... h6h5 [%c_effect h5;square;h5;type;Brilliant;persistent;true] Anand's enormous understanding of the game in action $1 The modest h-pawn threatens to fix the whole white kingside while gaining strong outposts in the king's neighborhood. 20. g2g3 [%c_effect g3;square;g3;type;GreatFind;persistent;true] The best reply. 20... c7c5  21. g1g2  21... f7g6  22. e4e5  22... f6d5  23. e2e4 The endgame is generally desirable for White. 23... g8h7  24. h3h4  24... g6f5 Anand keeps the blockade and patiently waits for his window of opportunity. 25. c3c4  25... d5c7  26. a1d1  26... a8d8  27. f1e1  27... d8b8  28. e1e3 [%c_effect e3;square;e3;type;GreatFind;persistent;true] A nice idea $1 White needs open files for his rooks. 28... c7a6  29. e3f3  29... f5g6  30. f3e3 Only this is wrong $1 30... a6b4  31. e3e2  31... b8d8  32. e4g6  32... h7g6  33. f2f4  33... g6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] The worst has happened for the first player, who failed to get a chance to open files. Moreover, there are too many holes in his pawn chain, which the former world champion will use for comfortable infiltration. 34. g2f3  34... b4c6  35. e2e4  35... c6d4  36. f3f2  36... f5g4 This is unavoidable. The problem is that there is also a decisive breakthrough in the making. 37. e4e3  37... d8f8 [%c_effect f8;square;f8;type;GreatFind;persistent;true] With the unstoppable threat of g7-g5 $1 38. d1h1 [%c_effect h1;square;h1;type;GreatFind;persistent;true] The best chance. 38... g7g5 [%c_effect g5;square;g5;type;GreatFind;persistent;true] White's position falls apart. 39. h4g5  39... e7g5  40. e3e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] The last tricky try. 40... g5e7 [%c_effect e7;square;e7;type;GreatFind;persistent;true] But Anand sees everything. 41. f4f5  41... g4f5  42. f2g2  42... f5g6  43. e4e3  43... e7g5 The black pieces are unstoppable. 44. e3e4  44... d4c2
