context: 1. d2d4  1... g8f6  2. c2c3 A curious move order. Fedoseev is a creative player who likes to take his games to original positions. 2... d7d5  3. c1f4  3... c7c6  4. h2h3 Another rare move. 4... c8f5  5. b1d2  5... e7e6  6. g1f3  6... f8d6 White's opening setup is rather innocuous—Black already has comfortable equality. But chess is not just about the opening, not even at the highest levels. 7. f3e5  7... d8c7 Preparing ...Nbd7. 8. g2g4  8... f5g6  9. e2e3  9... b8d7  10. e5g6  10... h7g6  11. f4d6  11... c7d6  12. d1e2  12... b7b5 An optimistic plan that puts Black in trouble. He probably wanted to prevent c3-c4, but the medicine is worse than the disease. 13. g4g5  13... f6g8  14. h3h4  14... g8e7  15. e2f3 A strange queen move, probably played to protect the rook on h1, something useful after h4-h5. 15... h8h5 This is a \"mysterious rook move,\" although I suspect not the type that inspired Nimzowitsch to write about this theme in his classical book \"My System.\" Harikrishna blocks the advance of the h-pawn, but White can still open the game on the queenside when Black may be left with a misplaced rook. 16. f1e2 The position of the rook is shaky on h5. 16... d7b6  17. e3e4  17... b6c4 It's clear that Black is in big trouble here. White has many tempting continuations. 18. a2a4  18... c4d2  19. e1d2  19... b5b4  20. e4e5  20... d6b8  21. c3b4  21... b8b4  22. f3c3  22... a8b8 The only chance—Black has to sac the exchange to fight for counterplay. The knight has an excellent outpost on f5. 23. e2h5  23... g6h5  24. d2c2
