The Perfect Must-Win Game

In a short match of two games it is quite easy to get your back to the wall. This is exactly what happened to Michael Adams after losing his first game to Victor Laznicka at the second round of the World Cup. He, however managed to coma back in the classical part of the match:

{A must win situation for Adams.} 1. e4 c5 2. Nf3 e6 3. d4 cxd4 4. Nxd4 Nc6 5.
Nc3 a6 {And a mini-surprise by Laznicka. Even though this is one of his pet
lines, he had not played it since 2013.} 6. Nxc6 bxc6 7. Bd3 d5 8. O-O Nf6 9.
Qf3 Be7 10. Qg3 O-O 11. Bh6 Ne8 12. Bf4 Bh4 13. Qf3 Be7 ({The trade of one of
the attacking white pieces makes sense} 13... Bg5 $5 14. e5 Bxf4 15. Qxf4 c5 {
as in Nepomniachtchi,I (2705)-Andreikin,D (2720) Moscow 2015}) 14. Na4 $1 $146
{[%cal Gc2c4,Gb2b3] Diagram [#] A strong, fundamental novelty. Adams intends
to stop the opponent's play in the center and on the queenside and start
kingside attack.} ({Previously only the obvious} 14. Rad1 {has been seen. After
} Nf6 15. h3 Nd7 16. Qg3 Bh4 17. Qh2 Ra7 18. Na4 Re8 {Black managed to hold in
Nepomniachtchi,I (2714)-Grachev,B (2669) Kazan 2014}) 14... Nf6 15. b3 Qa5 ({
Black cannot win the bishop pair as after} 15... dxe4 16. Bxe4 Nxe4 17. Qxe4
Bb7 18. Rad1 {Diagram [#] his queen lacks good squares} Qc8 (18... Qa5 19. Rd7)
19. Nb6 $18) ({Perhaps} 15... Bb7 {was better} 16. e5 Nd7 17. c4 $14 {At least
Black stops the kingside advance for the time being. Next he can try to
fianchettoe the dark-squared bishop.}) 16. e5 $1 {The attack can be successful
only with the center closed.} Nd7 17. Qg3 {With the threat Bf4-h6.} Re8 18. h4
c5 19. c4 $1 {[%csl Yc5,Yd5,Rg8][%cal Gh4h5,Gh5h6] Diagram [#] Once that the
center is blocked White can concentrate his efforts on the kingside.} d4 20. h5
Qc7 21. Rae1 {[%csl Ge5,Yg8][%cal Ge1e5,Rh1h8,Rb1h7,Rg3g8] Overprotects the
key e5 square. In case of a need, White can also lift this rook along the
fourth rank. It is curious to find out that the computer considers this
position equal. For the human eye it is very obvious that White has all the
play, it is quite one-sided. He can prepare the attack in many ways- along the
fourth rank, along the h file, battery on the b1-h7 diagonal. And if these
resources are not enough, he can redeploy the knight from a4 to d3-f4 and h5.
At the same time Black does not even have room to maneuver on the kingside.}
Bf8 ({The same computer suggests now as best the defense} 21... Kh8 22. h6 Rg8
{which only shows how bad Black's position is.}) 22. Bg5 g6 {This makes things
easier for White as he now has a clear target. However, standing should not
help neither, for example} (22... Bb7 23. f4 Qc6 24. Re2 a5 {and now say
battery with} 25. Bc2 {[%csl Rh7][%cal Rg3d3,Rc2h7] Diagram [#] and Qg3-d3.
Sooner or later Black will have to weaken his kingside.}) 23. f4 Bg7 24. Qh4 {
Adams simply doubles his pieces on the h file.} Bb7 25. Kf2 $1 {Diagram [#]}
Rf8 ({Nothing changes} 25... Qc6 26. Be4 Qc7 27. Bxb7 Qxb7 28. Rh1 $18) ({If}
25... Nf8 26. Bf6 Bxf6 27. exf6 {and White will find a way to reach the black
king via the dark squares or the h file.}) 26. Rh1 f5 {Desperation.} 27. hxg6
hxg6 28. Qh7+ Kf7 29. Rh6 {Diagram [#] A very convincing win for the English
top GM.} 1-0

Adams then managed to win the rapid-blitz game(s) at the end of a long and exhausting match.
