22. h4 |
White blocks the h5 pawn from potentially advancing to h4. Now Black's Nf5 is very hard to kick out, because the h3 pawn wouldn't be supporting a possible g4 advance. | |||||||
| | ||||||||
|
22... Bd4 |
Black is trying to setup a little tactic. Now Black is threatening 23...Nxg3, because the f2 pawn can't take back because it's pinned by the Bd4, and if White takes back with the queen, Black plays Qxg3 and gets a free queen, as the f2 pawn still can't take back on g3. If White played Qxd4 after Black's Nxg3 (because the knight is no longer defending the Bd4), then Black can play Nxe2 , forcing the White king to move, and then capturing the queen on d4 by Nxd4. | |||||||

23. Bf4 |
White attacks the Qc7, so Black has no time to play his Nxg3. But Black has a backup plan. | |||||||
| | ||||||||
|
23... e5 |
Black advances his e-pawn, attacking the Bf4. Now Black's centre is starting to take control of the board. | |||||||
| | ||||||||
|
24. Be3 |
Retreating the bishop and unpinning the f2 pawn. This bishop becomes subject to attack in Black's next few moves, but other squares for this bishop weren't any better. | |||||||
| | ||||||||
|
24... e4 |
Black unleashes the Qc7's power to g3, and gains time by attacking White's Qd3. | |||||||
| | ||||||||
|
25. Qb3 |
Retreating the queen. | |||||||
| | ||||||||
|
25... Bxe3 |
Black has seen a way to win material. If White takes back by the f-pawn, then Black can play either Nxg3 attacking both White rooks, or Qxg3 with an attack on the White king. But White can also take back with the rook. | |||||||
| | ||||||||
|
26. Rxe3 |
White decides against taking back with the f-pawn, but this way allows an exchange of the Nf5 for the Re3. This exchange favours Black, because rooks are generally superior to knights in most situations. | |||||||
| | ||||||||
|
26... Nxe3 |
Winning a rook for a minor piece (knight or bishop) is called 'winning the exchange', and Black has just done that. | |||||||
| | ||||||||
|
27. Qxe3 |
White doesn't take back with the f-pawn because then the g3 pawn will hang. | |||||||
| | ||||||||
|
27... f5 |
Black strengthens his pawns. Note that the only weak points in Black's pawn structure are g6 and c6, both of which are very hard to attack. | |||||||
| | ||||||||
|
28. f4 |
White tries to lock the position up in the hope that his knight will prove more useful in the fight, because knights can jump over other pieces and aren't limited by closed pawn structures. | |||||||
| | ||||||||
|
28... Rfd8 |
Black now wants to play d4, which would push the White queen back and gain space for Black's pieces. | |||||||
| | ||||||||
|
29. Qd4 |
White prevents d4 by occupying the square. | |||||||
| | ||||||||
|
29... Qg7 |
Black forces a queen exchange. The only way for White to avoid a queen exchange is to retreat the queen, which would allow 30...d4. | |||||||
| | ||||||||
|
30. Rd1 |
White defends the Qd4, intending to take back on d4 with the rook in the event of 30...Qxd4. This keeps the d4 square occupied, and keeps preventing the d4 pawn move by Black. White didn't play 30.Qxg7 instead, because after 30...Kxg7, White wouldn't be able to prevent 31...d4. | |||||||
| | ||||||||
|
30... Qxd4+ |
Black exchanges queens, because the resulting endgame is winning for Black. | |||||||
| | ||||||||
|
31. Rxd4 |
Note how White still prevents the d4 move, because now it is blocked by the rook. | |||||||
| | ||||||||
|
31... Ra4 |
I won't explain this move, to avoid confusion. | |||||||
