1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1c4  3... f8c5  4. c2c3  4... g8f6  5. d2d4  5... e5d4  6. e4e5 Probably the most fashionable Italian line nowadays. 6... d7d5  7. c4b5  7... f6e4  8. c3d4  8... c5b6  9. b1c3  9... e8g8  10. c1e3  10... f7f6  11. e5f6  11... e4c3  12. b2c3  12... d8f6  13. e1g1  13... c8g4 And this pin is still there. 14. b5e2  14... g4f3 This is the second most popular choice, although Black is not forced to part with his bishop pair. 15. e2f3  15... a8d8  16. f3e2 The bishop has done its job, and now it is time to look for a better diagonal. 16... c6a5 This move is a novelty. The knight needs to step out of the pawn's way for the black bishop, which has also done its job and seeks a better diagonal. 17. a2a4  17... c7c6 That's the plan. 18. e2d3  18... b6c7 Ganguly is following his path. 19. d1g4  19... d8e8  20. a1e1 Now Erigaisi consolidates and starts building concrete threats. His bishops will soon prove priceless. 20... c7d8 A prophylaxis against the Be3-g5 maneuver. 21. g2g3  21... f6f3 Ganguly must have miscalculated something. This move only helps White! 22. g4h3 The queen communicates well with the bishops, and the black kingside is defended by just two pawns. So why trade? 22... g7g6  23. d3e2  23... f3f5  24. e2g4 This is the more dangerous of the two bishops as it does not have an opponent. 24... f5f6  25. e3f4 Beautiful, harmonious play by the pair! Once the kingside has been softened, they look to occupy the free diagonals close to the enemy king. 25... h7h5  26. g4d7 This not only wins the open file, but Erigaisi is preparing the decisive infiltration. 26... e8e1  27. f1e1  27... g8h7  28. e1e6  28... f6f7  29. e6d6 Through the sixth rank, the rook get access to the seventh one! 29... f7e7  30. d7e6 That is it; the light squares cannot be defended. 30... f8f4  31. d6d7  31... f4f6
