1.e4
This game was played in 1992 between strong grandmasters. White starts with 1.e4, leading to a classic Ruy Lopez where both sides slowly manoeuvre for many moves.
9...Nb8
Black plays the Breyer move ...Nb8, planning to reroute the knight to d7 and later support ...c5 and ...Bb7. From d7 the knight no longer blocks the c-pawn or the light-squared bishop.
10.d4
White gains space in the centre with d4, challenging Black's e5 pawn and opening lines for the pieces.
11.Nbd2
White starts the famous knight manoeuvre Nbd2–f1–g3, aiming to place a knight on the kingside to attack and support e4 and f5.
12.Bc2
White reinforces the e4 pawn and clears the b-pawn. Later White can play b3 or b4 and develop the c1-bishop to b2 if needed.
12...Re8
Black prepares to redeploy the dark-squared bishop via f8–g7. From e8 the rook also supports a future ...d5 break in some lines.
13.a4
White attacks the b5 pawn and gains space on the queenside. Later the open a-file can be used by White's rooks.
13...Bf8
Black steps the bishop back to f8, preparing ...g6 and ...Bg7. Playing an early ...c5 is possible but can leave Black with weak queenside pawns.
14...c6
Black finally plays ...c6. Capturing on a4 would open the a-file and make the a6 pawn weak, so Black supports the centre instead.
15.b3
White solidifies the queenside. The notes mention that 15.b4 is also strong but forces White to clarify the pawn tension a bit earlier than needed.
17.Bb2
White develops the bishop to the long diagonal and reaches the same setup recommended in the theory section. From here the game leaves known lines and becomes original play.
17...Nh5
Black begins a knight journey toward f4. To reach the strong f4 outpost, the knight must first step to the edge of the board on h5.
18.Bf1
White quietly tucks the bishop back so that ...Nf4 will not come with a tempo on the bishop. This is a typical Karpov-style prophylactic move.
18...Qb6
At first glance this looks natural, but it actually allows White's main strategic idea: b4 followed by dxe5 and c4, gaining space and activity on both wings.
19.b4
A key move! White fixes pawns on dark squares and increases control of the c5-square, preparing the powerful plan dxe5 followed by c4–c5.
19...Nf4
Black finally reaches the f4 outpost. The notes say that Karpov's reply in the next moves is a model way to meet this knight jump.
20.dxe5
White starts a very accurate strategic combination by taking on e5. This opens lines and prepares to use his space advantage and piece activity.
20...Nxe5
Black recaptures with the knight. Taking with the d-pawn was also possible, but that would leave the bishop on g7 less active behind its own pawn chain.
21...dxe5
Black prefers to take with the pawn instead of the bishop. If Black captured with the bishop, the d6 pawn would become weak and White would enjoy a very strong kingside pawn majority.
22.c4
White opens the diagonal for the dark-squared bishop and increases pressure on the b5 pawn. The queenside space advantage starts to tell.
22...Rad8
Black brings a rook to the d-file, but the notes explain that taking on c4 would just help White activate the pieces further and even trap the queen in some lines.
24.Ra5
White doubles down on queenside control, dominating the a-file and attacking the b5 pawn from the side with the rook.
25.Bc3
Instead of immediately pushing c5, Karpov calmly increases pressure on b5. The c4–c5 break will still be available later if he needs it.
26.Nf3
White reorganizes the knight toward better squares. Now Black's e5 pawn becomes a long-term target as well.
26...Nd4
Black's knight on d4 is his best piece. The notes emphasise that White should exchange this piece to remove Black's active counterplay.
28.c5
White locks Black's queenside and gains even more space. It is hard to name a single truly active Black piece after this move.
29.Ra7
White's rook invades the seventh rank, attacking pawns and tying down Black's pieces to their defence.
30...d3
Black pushes the d-pawn as his only real try for counterplay. Karpov calmly reorganizes and later wins this pawn.
32...Rd4
Black sacrifices a pawn to activate the rook. The notes explain that even with this activity, Karpov's technique will gradually neutralize the counterplay.
33.e5
White returns the extra pawn to open lines and start a kingside attack. The follow-up e5–e6 will strongly expose Black's king.
34.e6
White pushes e6, opening the centre and taking advantage of Black's unprotected king. Black's scattered pieces can no longer defend effectively.
35.Rxe6
White crashes through on the e-file. The notes highlight that the black king is now a huge weakness with rooks and queen ready to attack.
38.Ne4
White's knight also heads toward the black king. From e4 it can jump to f6 or g5, adding to the mating threats.
38...Qd8
Black tries to guard against ideas like Ng5 and Nf6, but this queen move actually blunders the rook on f4 in the final tactic.
39.Qe5+
The final blow: Qe5+ wins the rook because Black cannot defend it and handle the check at the same time, so he resigns.
