{[#]} 13... Rc8 $3 14. h5 {My opponent didn't believe in Black's attack and
goes for the most critical move.} Bxc2 $1 {The point of Black's previous move.
Bxc2 lures the White queen to a vulnerable square, and after Nbxd5 and e4,
Black's pressure along the e- and c-files will be extremely dangerous.} 15. g5
$1 {This is probably best, hitting the knight on f6 before taking on c2.} (15.
Qxc2 Nbxd5 $1 {it's important to take with this knight, which might otherwise
be out of play. After} 16. Bd2 {Black's other knight joins in with} e4 $1 {
[%cal Gd5b4,Gb4d3] With threats of Nb4-d3-f2 and exf3, Black's attack is
crushing}) (15. Rc1 $5 {would be great for White if not for} e4 $1) 15... e4 $5
{Entering deeper into the crevasse. If White takes on c2 then Black takes on
f3 and if White takes on f6 then Black simply recaptures with the bishop,
opening up the rook on the e-file. During the game I felt like Black should
have enough compensation, but of course now the all-mighty Stockfish is able
to find a way out for White.} ({I also considered the objectively superior} 
15... Nfxd5 16. Nxd5 Nxd5 17. Qxd5 Bxg5 18. Bxg5 Qxg5 $44 {where Black has
three pawns for the piece and White's king is staying in the center for the
rest of the game, but I felt this position was kind of simplified and would be
easier for my opponent to play compared to the game.}) 16. f4 {Trying to keep
the position blocked, while keeping the threat on Black's Bc2 and Nf6.} ({
It turns out it was stronger to first grab on f6:} 16. gxf6 Bxf6 {and then push
} 17. f4 $1 $16 {When I originally analyzed this game with the engines of the
time, they all thought Black's play was completely sound! So much for my
brilliancy :D}) (16. Qxc2 $2 exf3) 16... Ng4 {A key resource for Black,
hitting the bishop on e3.} 17. Bh3 $5 {From afar I overlooked this move,
believing that as long as I could play Nxe3 and take White's dark-squared
bishop my position would be OK. At first I thought my luck had run out and I
might be worse, but after spending another 20 minutes here I was able to find
the only winning line:} (17. Bxb6 {was also possible, winning a piece, but at
the cost of activating Black's queen:} Qxb6 18. Qxc2 Qf2+ 19. Kd2 Qe3+ 20. Ke1
{on my opponent's time I spotted} Bd8 $1 {as a strong way to continue the
attack, and calculated the following completely unnecessary line:} 21. Rh3 Qf2+

and if 18...Qxc8 19.Qxe3 Black wouldn't have enough compensation as the bishop
on e7 is hard to activate. Hence my eureka moment:} Ng2+ $1 19. Kf1 Nxf4 $1 {
This is perhaps the move I'm most proud of, completely dismantling White's
position. It's hard not to feel like Shirov when playing such a move, setting
the board on total fire. The point is that after 20.Nxf4 Bxg5 I'm threatening
21...Qf6, with play against White's king and several of White's undefended
pieces.} 20. Bg4 {A reasonable try, but still Black is able to get in on the
dark-squares.} (20. Nxf4 Bxg5 21. Qxc2 Qxc8 22. Nfe2 Nxd5 $19 {with threats of
Ne3+ and Nb4.}) (20. Qxc2 Qxc8 $1 {and White has nothing better than} 21. Nxf4
Bxg5 $19 {transposing to the above line.}) 20... Bxg5 21. Qxc2 Qf6 $1 {Black
is a full rook down, but White's king is now under heavy fire and Nbxd5 is a
huge threat.} 22. Rh2 ({White loses everything after} 22. Kg1 Nxe2+ 23. Bxe2
Be3+ 24. Kh2 (24. Kg2 Qg5+) 24... Qh4+ 25. Kg2 Qg5+ 26. Kf1 Qg3 $1 $19) 22...
Nbxd5 $1 $19 {Finally the b6 knight comes into play and lands the decisive
blow, threatening Ne3+.} 23. Kg1 Nxe2+ {Simply collecting material, as the
rook on a1 hangs.} 24. Bxe2 Nxc3 25. Rf1 Qe5 26. Kh1 Nxe2 27. Qxe2 d5 {With
four pawns for the exchange, Black's position is now completely winning. It
took me longer than I care to admit to actually finish the game, but the
result was never in doubt!} 28. Qg4 f6 29. h6 e3 30. Qd7 Qe4+ 31. Kg1 gxh6 32.
