context: 1. f2f4 One of the most interesting things about this tournament is looking at how the \"theory\" of each position developed in the other games of the round. This first move was tried in three games, while in two the always good 1.e4 was chosen. 1... f7f5  2. g2g3  2... g7g6  3. e2e4 White strikes in the center. It's also possible to finish development first. 3... f5e4  4. e1e4  4... d7d5  5. e4e2  5... b8d7 It's not clear that this is the best square for the knight. 6. d2d4  6... h7h6 The idea of ​​this move is to break the white structure with g6-g5 and offer the excellent b1-h7 diagonal for the bishop. This could also be done immediately with 7. d1e3  7... c7c6  8. c2c3 Defending the pawn, but White has an interesting alternative: 8... g6g5  9. b1d2  9... g5f4  10. g3f4  10... g8h7  11. c1a1  11... e7e6  12. d1e1  12... e8g6 The queen and bishop battery looks very dangerous, but the knights keep the king safe for now. White can try to disrupt the battery since the queen is somewhat exposed on g6. 13. f1f3  13... d8f7  14. h1g2  14... c8a8  15. g2h3  15... f7d6
