There will be a transposition to a more familiar position in a few moves. 5. b1c3  5... e7e6  6. e1g1 This is a position known to theory, with almost two hundred games in the database. 6... f8e7  7. b2b3 A natural way of developing the bishop. 7... e8g8  8. c1b2  8... d7d6 [%c_effect d6;square;d6;type;Inaccuracy;persistent;true] A passive move that leaves White with a comfortable position after the e3/d4 plan. 9. e2e3  9... c8d7  10. d2d4  10... c5d4  11. f3d4 A new move. 11... a7a6  12. d1d2  12... a8c8  13. a1c1  13... b6a7  14. f1d1 White has a good position, with more space. The two bishops cross the board and are far superior to their two colleagues. Even so, Black's position is solid and the d6-pawn is the only weaknesses. 14... c6d4 A good decision - Fedoseev doesn't like to wait. 15. d2d4  15... a7d4  16. d1d4  16... d7c6 After this move Black has a passive position again. 17. c1d1  17... c6g2  18. g1g2  18... f8d8  19. b2a3  19... f6e8  20. d4d3  20... c8c6 Black's problem is that his position is passive and there's no clear plan. 21. a3b4  21... g8f8  22. e3e4  22... e8c7  23. a2a4  23... f8e8  24. a4a5  24... b7b5  25. a5b6  25... c6b6  26. b4a5  26... b6b7  27. e4e5 [%c_effect e5;square;e5;type;Inaccuracy;persistent;true] A creative attempt, but it's not the best move. 27... d6e5
