[%c_effect g6;square;g6;type;Inaccuracy;persistent;true] It doesn't seem necessary to lose time before developing the bishop.
1. e2e4  1... c7c6  2. d2d4  2... d7d5  3. e4e5  3... c8f5  4. g2g4 An ultra-aggressive option against the Caro-Kann Defense. 4... f5e4 [%c_effect e4;square;e4;type;GreatFind;persistent;true] The most accurate move, provoking the white pawn to f3. 5. f2f3  5... e4g6  6. h2h4  6... h7h5  7. e5e6 This move is the point of White's opening idea: a pawn sacrifice to create weaknesses around the opponent's king. But now Black is not obliged to accept the gift. 7... d8d6 [%c_effect d6;square;d6;type;GreatFind;persistent;true] 8. e6f7  8... e8f7 [%c_effect f7;square;f7;type;Inaccuracy;persistent;true] Probably Abdumalik was already out of preparation, as the computer doesn't like this move and the capture with the bishop was played almost unanimously before. 9. g4g5 [%c_effect g5;square;g5;type;Mistake;persistent;true] 9... e7e5  10. g1e2  10... g8e7  11. f1h3  11... g6f5 [%c_effect f5;square;f5;type;GreatFind;persistent;true] 12. h3f5  12... e7f5 It's clear that the opening was a complete success for Black. Her king, even on f7, is safer than White's, the knight on f5 is very well placed, and her remaining pieces have free development, while White has barely left the first rank. Quite a result for just over 10 moves in the Caro-Kann $1 13. d4e5  13... d6e5  14. c1f4  14... e5e6  15. d1d2
