1. e2e4  1... e7e5  2. g1f3  2... b8c6  3. f1b5  3... a7a6  4. b5a4  4... g8f6  5. e1g1  5... f8c5 A tricky move order in the Arkhangelsk Variation. I remember this was recommended to me by my friend GM Ivan Morovic in 2001, but I was too lazy to study it and I was happy playing the Sicilian. 6. c2c3  6... b7b5  7. a4b3  7... d7d6  8. d2d4  8... c5b6  9. h2h3  9... c8b7  10. f1e1  10... h7h6 [%c_effect h6;square;h6;type;Interesting;persistent;true] An interesting move to avoid the annoying pin with Bg5. 11. c1e3  11... e8g8  12. b1d2  12... f8e8  13. d4d5  13... c6e7  14. e3b6  14... c7b6  15. f3h4 [%c_effect h4;square;h4;type;Inaccuracy;persistent;true] This is a superficial move. I think that, in general, the absence of the move a2-a4 was the reason for White's downfall in this game. 15... b7c8  16. d2f1  16... e7g6 [%c_effect g6;square;g6;type;GreatFind;persistent;true] A new move. It reminds me of the famous Ng6 from the fifth game of the Spassky-Fischer 1972 match. 17. h4g6 Considering how easy Black's position is to play after this move, maybe it's worth considering the sad retreat of the knight, although this is an admission of failure. 17... f7g6  18. f1g3  18... e8f8 The best thing in chess happens when you have a clear plan and just know what to do if your opponent sits and waits. Dronavalli is ready to play Nh7-Ra7-Raf7-Ng5 and then sacrifice something on the kingside. White desperately needs to create some play and trying to open the queenside with a quick c4 or a4 is the only hope. In the game the advantage soon becomes winning. 19. d1d2  19... f6h7  20. d2e3  20... a8a7 [%c_effect a7;square;a7;type;GreatFind;persistent;true] 21. g3f1  21... a7f7  22. f1d2 The position is so bad that White offers the f2-pawn in order to get some defensive chances. 22... h7g5  23. b3d1  23... f7f4  24. e1f1  24... c8d7 This doesn't spoil anything, but it is a bit slow. The position screams for a sacrifice. 25. a2a4 The counterplay comes too late. 25... b5a4  26. c3c4  26... b6b5  27. c4b5  27... a6b5 Apart from the attack, Dronavalli now is a pawn up. 28. b2b3  28... a4b3  29. a1b1
