Nc3 Bg7 4. e4 d6 5. h3 O-O 6. Be3 e5 7. d5 Nfd7 { This looks wrong to me since it blocks the bishop on c8 and takes the d7-square away from the queen knight. More common and logical are moves like 7...a5 or 7...Na6 } 8. g4 Na6 9. Nge2 Ndc5 10. Qd2?! { This move is a bit inaccurate since it's not clear that the queen should be on d2. However, the e2-knight will only make sense on g3, so playing 10.Ng3 is better and also makes more sense. } (10. Ng3 f5 11. gxf5 gxf5 12. exf5 Bxf5 13. Nxf5 Rxf5 14. Qg4 $16 { White could have also played differently, but compared to the game, this line shows why keeping the queen on d1 had advantages. The queen is much more active on g4 than on d2. }) 10... f5 11. gxf5 gxf5 12. exf5 Bxf5 13. Ng3 Qd7?! { Funnily enough, black makes a similar inaccuracy as white on move 10, moving the queen up one square where her movement is limited by a bishop. } (13... Bg6 14. h4! { It's important to take the h4-square away from the black queen. } (14. O-O-O? { Now this move is a big mistake since the black queen can come into the attack } 14... Qh4! 15.

Bxf6 Qxf6 20. h5 Qxf2 21. Qxf2 Rxf2 22. hxg6 hxg6 $13 { This position looks quite unclear to me, the engine says that it is equal, but a real game could go either way. }) 14. O-O-O { I thought for 8 minutes before this move since it looked quite scary to me. But during my calculation, I didn't see a way for black to explain the open b1-h7 and c1-h6 diagonals. } 14... Nb4 { I was very happy to see this move since I felt that it game white quite a pleasant advantage. } (14... b6 15. Rg1 Kh8 16. Nb5 Ne4 17. Nxe4 Bxe4 18. b4 $14 { Objectively, this should be about the same as the game continuation, but to me it looks less pleasant than the game since the white king seems a little unsafe. }) 15. Bxc5 dxc5 16. a3 Na6?! $16 { Now the knight is out of the game and while playing, I was very happy with my position. White's king is safer, white has the better structure and black is practically playing a piece down at the moment. } (16... Bg6! { I didn't even consider leaving the knight on b4 during the game, but apparently, this and 16...a5 are black's only chances to stay in the game } 17. axb4 cxb4 18. Nce4 Qa4 { Now black can try to exploit the open king } 19. Bd3! b3 20. Qe3 { White needs to make room for the king } 20... Rf4 21. Ne2 Qa1+ 22. Kd2 Qxb2+ 23. Ke1 Rf7 $16 { White is better due to the material advantage, but black has certainly gained a lot of counterplay and white has to be careful. }) (16... a5 17. h4! { All of this makes little sense to me, but Stockfish prefers white's position at the end of the line. } (17. axb4?? axb4 18.

Rg3 { With this I intended to sac the pawn on f2 } (21. Rg2 Rd4 { This bothered me during the game }) 21... Raf8 22. Rdg1 Rxf2 23. Qe3 e4 { This was a surprise but white is much better due to the knight on a6 } 24. Bxe4 Qd4 { Another unexpected move } (24... R8f6 25. Bxg6 hxg6 26. Rg4 Rf1+ 27. Rxf1 Rxf1+ 28. Kc2 Rf6 29. Rh4+ Kg8 30. Re4 $18 { Intuitively, it wasn't very clear to me that white is winning in this position, but looking at it more deeply, it's clear that black is in deep trouble since their king is more open and their pieces are less active. }) (24...

Re7+ Rf7 32. Rxf7+ Kxf7 33. Kd3 (33. Nxa7 { This should still win, but it's a bit more difficult for white. }) 33... Kf6 34. Ke4 Kg5 35. Ke5) 31... Nb8 (31... Kf6 { I had expected this move during the game and wasn't sure how white can make progress. White is a pawn up and has the better structure, but the black king is getting active, the white knight is currently out of the game and if the rook leaves the third rank, black has Rf3+ picking up the h3-pawn. But there is a concrete way for white to win } 32. Nb5 Kg5 (32... c6 33. Re6+ Kf7 (33... Kg5 34. dxc6 bxc6 35. Rxc6) 34. Nd6+ Kg7 35. Nxb7 cxd5 36. cxd5 $18) 33. Nxc7!
