1. g2g3  1... d7d5  2. f1g2  2... g8f6  3. g1f3  3... b8d7 An interesting and modern idea, usually implemented by creative players. If White plays d4, Black sometimes goes with the knight to the strange square on b6. 4. e1g1  4... e7e5  5. d2d3 Can we call this a Pirc Defense with reversed colors or is that pushing the envelope $2 Regardless of how best to name this position, the computer is not very impressed with White's system. 5... c7c6  6. a2a4 The objective of this move is not very clear, and I understand why it has never been played before. But, to be honest, it's not so bad and the pawn can be useful on a4 at some point, either to prevent b7-b5 or to play a5 to gain space. In any case, Black responds with a move that is equally practical and enigmatic. 6... a7a5 Why not $2 7. b1c3  7... f8b4 A good square for the bishop when the knight is on c3 and the pawn on a4. This means it can capture the knight at some point and cannot be attacked by a pawn on a3. 8. e2e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] Unafraid of spoiling the pawn structure. 8... d5e4  9. c3e4  9... e8g8 [%c_effect g8;square;g8;type;Inaccuracy;persistent;true] 10. c1g5  10... b4e7 [%c_effect e7;square;e7;type;Inaccuracy;persistent;true] 11. e4f6  11... e7f6  12. g5f6  12... d8f6  13. f1e1 Black has problems defending the pawn on e5 in the long run, so his next move is the best chance to fight for equality. 13... e5e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] 14. f3d2 A difficult and surprising move. Technically it deserves to be annotated as dubious, but I'm unable to do that. Sorry. 14... e4d3  15. d2e4  15... f6b2 Accepting the duel. 16. d1d3 This is the kind of position Dubov likes, with plenty of initiative and a minimal material investment. 16... d7e5  17. d3d6  17... e5c4  18. d6c5  18... b2b4 [%c_effect b4;square;b4;type;Inaccuracy;persistent;true] 19. c5h5 [%c_effect h5;square;h5;type;GreatFind;persistent;true] There are many examples of kings who perished because they didn't have a single minor piece protecting their castled position. This is a good sign that an attack is promising. Furthermore, Black's queen is far away. The position is very dangerous. 19... h7h6 [%c_effect h6;square;h6;type;Inaccuracy;persistent;true] I draw the reader's attention to Dubov's ingenuity in developing his initiative from now on. 20. c2c3  20... b4b6  21. g2f1 [%c_effect f1;square;f1;type;GreatFind;persistent;true] White's moves are connected with clockwork precision. 21... c8e6 The only way to protect the knight. 22. f1c4  22... e6c4  23. e4f6 [%c_effect f6;square;f6;type;Brilliant;keyPressed;undefined;persistent;true] A brilliant and thematic combination to destroy the king's position. 23... g7f6 [%c_effect f6;square;f6;type;Inaccuracy;persistent;true] This loses immediately. 24. e1e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] 24... c4d3  25. e4g4  25... d3g6  26. h5h6
