My opponent decided to go for the most concrete. } 18. d5 { I had a lot to calculate here. } 18... exd5! (18... e5? { I considered this move to shut down the Bishop on b1 and worsen the Knight on f3. However, White can quickly get the pieces back into play, and White should try to solve one of those two problems with his next move. } 19. Bd3! (19. Nh4 { Trying to get the Knight to f5. While this is also good for White, Black manages to solve some problems. } 19... Qc3 { White should try to avoid the Queen trade. } 20.

White will trade the Bishop for the Knight and reach a superior endgame. }) 20. Nh4 { But now the Knight reaches f5. } 20... Qc3 21. Qe3 $18 { Avoiding the Queen trade. With the Queen on e3 - compared to on e2 - Black can not play g6. White is much better. }) (18... Ne5 19. d6 Nxf3+ 20. gxf3 Qd7 21. e5 { With the Queens still on the board, Black isn't in time for counterplay with .. .g5 and ...f6, and thus White's passed pawn is too strong. } 21...

Nh4!? { A move I had not considered at all. I had seen that the Knight could not go to d4, but by going this way, the threat of Nf5 is renewed. I experienced some form of panicking here - and poor calculation led to a poor move. } (20. Nd4 { There are no tricks with this move. } 20... Qxd5 $19) 20...

Qxd5 $19 { Black just picks up the pawn. }) 21... g6 { Looking at it now, I find it rather strange why I didn't play like this. With the Queen on d2, ...g6 is not an option, so first trading on e1 to then play ...g6 is very natural. It actually turns out that White has a very difficult time keeping the balance here. } 22. Bf5! { A spectacular but necessary move. There are many fine moves for Black here, but I'm not sure what the most natural way to play is. } 22... Rc5 { I like the idea of this move, but it seems a bit counter-intuitive to leave the 8th rank unprotected. } (22... gxf5 { This is also possible and perhaps a bit more ambitious. There is no mate, but White will give up two pieces for a Rook and a pawn. } 23. Nxf5 Qe5 { I find it the most natural to trade the Queens due to the weakened pawn structure around the black King. } (23... Qf6 { Black can also keep the Queens on the board. } 24. Ne7+ Kf8 25.

Bc2!! { The only winning move. Avoiding the Queen trade, and now actually attacking the Knight on c4 which doesn't have anywhere good to go. } 26... b5 27. d7 $18 { The Queen is too far away from the defence and the game should be over. It's funny how everything seems so simple afterwards when you sit at homw with your engine on. }) 26... Qf6?! (26... b5 { The best move according to the engine, just allowing Nxh6+.

Rc1! { Taking the file furtherst away from the opponent's King! This is a common principle that also works in this position. It is not easy finding a good move for Black, since White is threatening Rc7, and the Knight can't go back to c4. } 29... Ba6 (29... Na4 { The Knight can try this. } 30. Rc7 Nc5 31. a3! { Incredible. White threatens Ba2, and now Black has to find } 31... Be4! 32. Bxe4 Nxe4 33. d7 { With the threat of Rc8 } 33... Kh7 34.

I don't think it makes much sense to allow White to play g4 uncontested } 40. g4 b4! { This is the way to make a draw, but the road ahead is still narrow for Black.
