1. d2d4  1... g8f6  2. c2c4  2... c7c6  3. g1f3  3... d7d5  4. b1c3  4... e7e6  5. e2e3  5... g7g6 This move leads to a passive position of the Schlechter Defense with the pawn advancing to e6. Of course, advancing the pawns to e6 and g6, especially at the beginning of the game, is not so logical. Both moves have the same main objective: to free the bishop's path. The great merit of this move, and to be honest perhaps the only one, is taking Caruana out of his usual high-level preparation. It must be admitted that Rapport's strategy will have some success. 6. f1d3  6... f8g7  7. e1g1  7... e8g8  8. e3e4 It's also possible to play a slower, more maneuvering game with 8.b3. It's hard to say which is better. 8... d5e4  9. d3e4 At first glance, this move seems very clever, provoking the exchange of the knight for the bishop in a favorable situation for White. Rapport's next excellent move, however, shows the shortcomings of the bishop capture. 9... b7b5 [%c_effect b5;square;b5;type;GreatFind;persistent;true] A creative resource and the best move. 10. e4d3  10... b5c4  11. d3c4  11... c8a6 [%c_effect a6;square;a6;type;GreatFind;persistent;true] The exchange of bishops is desirable for Black. 12. c4a6  12... b8a6  13. d1a4 My impression is that this is not the most precise move, since the queen is not doing much on a4, a square better suited for the knight. 13... d8b6  14. c1f4  14... f8d8  15. f4e5  15... a6b4  16. f1d1  16... b4d5  17. a4c2 The position is a little trickier now. White is preparing Na4, preventing c6-c5, and leaving Black with a passive position. 17... g7f8  18. f3g5 A somewhat surprising move. The knight is going to e4, but it looks a bit superficial. 18... f6g4  19. e5g3  19... f8g7 Here and on the next moves, Black must seriously consider the subtle 19...Nh6 with the intention of going with the knight to f5. 20. g5f3  20... a8c8 [%c_effect c8;square;c8;type;Inaccuracy;persistent;true] Too slow. 21. c3e4  21... c6c5 [%c_effect c5;square;c5;type;Inaccuracy;keyPressed;undefined;persistent;true] This is the last chance to maneuver the g4-knight to f5. Objectively Black may still be able to escape here; a draw is the likely result in a computer game from this position. But in human terms, the position is almost a losing one: Black will need to find a sequence that borders on the impossible in a few moments. 22. d4c5 [%c_effect c5;square;c5;type;GreatFind;persistent;true] The most dangerous reaction. 22... b6b2  23. c2b2  23... g7b2  24. a1b1  24... b2g7 [%c_effect g7;square;g7;type;Mistake;persistent;true] 25. d1c1 The c-pawn is ready to move forward. Black's position is critical. 25... g7h6  26. c1c4  26... h6f8 The rook on c4 is actually better than on c1. 27. c5c6  27... f7f5  28. e4g5  28... d8e8  29. b1b7  29... d5e7 Now Black's position collapses, but it's hard to make recommendations. 30. h2h3  30... g4f6  31. f3d4 The e6-pawn is falling. 31... h7h6  32. g5e6  32... e7c6  33. e6f8  33... c6d4  34. c4c8  34... e8c8  35. f8g6  35... c8c1
