1. b2b3 It's hard to resist the temptation to castle on the first move of a Chess960 game, especially if it's on the queenside. Or you could be solid and just go for the \"English Opening\" with 1.c4. Fedoseev's move, however, is also good. 1.b3 here is better than the same move in a normal chess position. 1... b7b6  2. d2d4  2... g7g6  3. b1d2 Preparing to control the center with e2-e4. 3... f7f5 A good move, preventing White's plan. 4. f2f3 Reinforcing the idea of playing e4, but also preparing a developing plan with Qf2, e3, Nd3, the bishop moves, and then kingside castling. 4... e8f6  5. c2c4  5... f8g7  6. e1d3  6... e7e6 The idea of this move is to control White's pawn advance with d4-d5. 7. e2e3  7... d7d6  8. f1e2  8... g8f7  9. g1f2  9... d8h8  10. d1h1 At some point Chess960 games become \"normal\" and you need to hope you have a good position when that happens. Here both players can be reasonably happy, as the position is close to equality. 10... b8d7  11. c4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] Gaining space on the queenside. 11... b6c5 [%c_effect c5;square;c5;type;Interesting;persistent;true] 12. d4c5  12... e6e5 This is the point of Black's play. He has good central control, but now Fedoseev exploits his chance with a very subtle move. 13. c5c6 [%c_effect c6;square;c6;type;GreatFind;persistent;true] A move that seems risky at first glance, since the c6-pawn is not that well-protected and losing it will be a tragedy for White. But the idea is well-supported tactically. 13... d7b6  14. c1c2 [%c_effect c2;square;c2;type;Inaccuracy;persistent;true] To demonstrate the advantage White has to employ a very exotic plan. 14... f7e8  15. f1c1  15... b6d5 [%c_effect d5;square;d5;type;GreatFind;persistent;true] Despite the trapped bishop on a8, the c6-pawn requires constant care and Black can use his good central control to divert attention from White's pieces. 16. h2h3  16... e5e4 [%c_effect e4;square;e4;type;Mistake;persistent;true] A hasty move - complications don't favor Black. It's better to play 17. f3e4  17... f5e4  18. d3f4
