1. … Ng3! This thematic knight sacrifice forces White to open up the h file onto his own king. 2. Bxg3 (2. hxg3 hxg3+ 3. Kg1 gxf2+ 4. Kxf2 may have been a better try, as White’s king is relatively safe.) hxg3 3. h3? A natural move, but one that loses to another thematic sacrifice: 3. … Bxh3! 4. Kg1 (4. gxh3 White gets checkmated after 4. … Qd7 and Qxh3.) 4. … Be6 5. Qd2? (Qe1 getting rid of the g3 pawn was necessary.) 5. … Bxd5 6. exd5 Kd7! 0-1

White cannot stop the threat of Rh1+ and Qh8+ Qh2#.
