Chapter 11
Knight Fork Distance
The main thing is to drive two enemy pieces, preferably king and queen, into forking distance. The main trick to achieve this is the decoy: once we notice that one piece is at forking distance, we must force the other one to go to the mined square.

White has a possible check on f6. He can use this opportunity to bring another piece into the attack:
24.Rd7!
24.Nf6+ was an alternative move order.
24…QC6
24…Rc7 25.Nf6+ Kh8 26.Rxc7 Qxc7 27.Qxe4+− attacking h7 and a8; 24…Qxd7 leads to the simple fork 25.Nf6+ and White wins.
25.Nf6+ Kh8 26.Qh4 gxf6 27.Rxf7 Bg7 28.exf6
1-0
Followed by 29.Rxg7 and mate.

Black is at checking distance of the white king. The time has come now to lure another major piece to the desired square, thanks to the following little combination:
10…Rxe3 11.Bxe3 Bg4
And after 12.Qxg4 Nxe3+ the ‘family check’ does the trick.

Very classical stuff here:
- the queen is already at knight fork’s distance;
- we need to force the king to go to a square at fork distance, and we can realize this thanks to the forcing
22.Rg8+ Rxg8 23.Rxg8+ Kxg8 24.Nxe7+
followed by 25.Nxc8, with a winning advantage.

A very nice job by the knight at the end of this game. White’s game is ruined in just two moves after
31…Nc3 32.Rb2 Rxb3!

The e3-bishop is at a knight’s distance from his king, and attacked by the knight on f5. Black uses this conjuncture to initiate an original tactic based on a royal fork:
18…Nxc4!
Luring the queen to knight’s distance.
19.Qxc4 Qxe3!20.fxe3
20.Qxc7 Qd3+ 21.Kc1 (21.Ke1 Bxc3+ 22.bxc3 Re8+ and mate) 21…Bh6+ leads to mate.
20…Nxe3+ 21.Ke2 Nxc4
With a great advantage in the ensuing endgame.
22.Rhf1+
22.Raf1+ was stronger, but Black is much better in all cases.
22…Ke8 23.Nd5 c6 24.Nc7+ Ke7 25.Nxa8 Rxa8

Kotov,Alexander
Soviet Union 1928
A well-known story was told by Kotov in his book Think like a Grandmaster. He was Black, who is completely winning here, and was to move. While he was thinking, his opponent wrote ‘resigns’ on his scoresheet, and to finish the game, Kotov decided to grab the bishop.
1…Rxf7?
1…Qf5, for example, would have won very quickly. Now the queen is at a knight fork’s distance. We have to force the king to move to a forking square, and this we manage with
2.Bd8+!+− (alignment)
Now Black, not White, had to resign, because after 2…Kxd8 3.Nxf7+ White is winning.
Knight Fork, and various tactics
Kopaev,Nikolay
Novopashin,Arkady
Rigatt 1954 (8)
In this game, we can see how tactical themes can flourish once a signal has been detected. Here, after White has wrongly retreated his rook at forking distance from the enemy knight, Black ma
kes use of many themes: line and square clearance (with …d4-d3 and …f5-f4), the pin (on g2 and e1), and the double attack (with …Qg4). The game is also interesting from Whites point of view: giving our opponent just one chance to enter favourable tactics can be enough to lose the game!
1.e4 c5 2.Nf3 Nc6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 e6 6.Ndb5 Bb4 7.a3 Bxc3+ 8.Nxc3 d5 9.exd5 exd5 10.Bd3 0-0 11.0-0 h6 12.Bf4 d4 13.Ne4 Nxe4 14.Bxe4 Qf6 15.Bg3 Bf5 16.Re1 Rfe8 17.Qd3 Rxe4 18.Rxe4 Qg6 19.Rae1 Kh7 20.Qf3 Bxe4 21.Rxe4 f5 22.Re2
This is an awkward placement for the rook, which gives the black knight forking chances. 22.Re1 was wiser. The game should be equal after, say, 22…f4 23.Bxf4 Qxc2 24.Qe4+ with a balanced ending.
22…d3!
Vacating the d4-square in order to fork with the knight.
23.Qxd3 Rd8!
Now another problem for White to solve is the back-rank mate.
24.Qc3
24…f4!
Another beautiful line clearance. The g-file is cleared, and as the g2-pawn will be pinned, a check with the knight on f3 will be available in some situations.
25.Bxf4 Qg4
Attacking e2 and f4.
If 25…Rd1+! 26.Re1 and now:
26…Nd4 would be the most aesthetic way to finish the game:
A) 27.Rxd1 Ne2+−+;
B) 27.Kf1 Qa6+28.Kg1 Ne2+−+;
C) 27.h3 Ne2+−+;
D) 27.Qb4 Rxe1+ (27…Nf3+ also wins) 28.Qxe1 Nf3+−+.
26.Bxh6
26.Re1 Qxf4 should win easily for Black.
26…Rd1+ 27.Re1 Nd4 28.h3 Nf3+29.Kf1
29.Qxf3 Rxe1+−+.
Now comes a glorious finish:
29…QC4+!!
0-1
If 30.Qxc4 Rxe1 mate.
Though our chapter is dedicated to knight forks, let’s take a look at two other short-ranged attackers:
Pawn Fork
Reshevsky,Samuel
Lasker,Edward
New York 1922
1.d4 Nf6 2.Nf3 e6 3.c4 d5 4.Nc3 Nbd7 5.Bg5 Bb4 6.Qb3 c5 7.e3 Qa5 8.Bxf6 Nxf6 9.Bd3
9.dxc5 Ne4 10.Rc1 Nxc5 11.Qc2 should have been preferred, with an unclear game.
Black noticed that queen and bishop are placed at pawn-fork distance, and played the unexpected
9…b5!
with a decisive advantage.
10.Qc2
10.cxb5 (on 10.a3, 10…bxc4 wins) 10…c4, winning a piece, is the point.
10…bxc4
And Black logically went on to win.
A King Fork
NN
Mannheimer
The black monarch is particularly active in the centre. Experts have estimated the power of the king in such an endgame position to be the equivalent of four pawns, that is, between the values of a bishop and a rook.
The king is effective thanks to its capacity of attacking every square around it – the only other piece that has such power is the queen. This gives him some opportunities to realize multiple attacks, like in this old game:
1…Re4!!
A decisive interpolation. White can take this rook in three ways, but in all cases, after Black takes back, the two remaining pieces will be simultaneously attacked, and one will be lost.
2.Bxe4
2.Rdxe4+ dxe4 or 2.Rfxe4+ dxe4 and in either case, a bishop and a rook are both ‘en prise’.
2…dxe4
The king attacks both rooks, and one of them will be lost.

Chapter 12
Trapped Pieces
The main thing is to identify the signal. The domination has to be spotted.
Once the motif of a ‘trapped piece’ has been noticed, the main themes in order to use it efficiently are:
- Line/square closing (in order to keep the prisoner from escaping);
- Line clearance (in order to open the line for attacking the piece);
- Elimination of the defender (of the trapped piece).

The a5-knight is trapped on the edge of the board. No defender can protect it after the simple line opener
12.Nd1!
Attacking the knight twice, and protecting b2 at the same time. White wins a piece.
12…Nxe4 13.Bxa5 Qa6
After this move, the queen is also in danger of being trapped. 13…Nc5+ was better.
14.Bxc4 b5 15.dxc6!
1-0
After 15…bxc4 (15…bxa4 16.Bxa6+−) 16.c7+ Ke7 17.Bb4+ wins the queen and the game. The simple 15.Be2 was also sufficient for a decisive advantage.

Noticing that the queen is trapped here is equivalent to solving the combination. White has to open the diagonal for the bishop:
37.Nf5! gxf5 38.Bf2
The domination theme is arguably the most important theme in chess tactics. As a matter of fact, it is the most normal way to end a game; here if the queen were a king, it would be checkma

The white pawns secure the first player a great space advantage, which means that the black pieces lack space to move. In this game, the first piece that appears trapped is the h7-rook; thus it looks natural to attack it with
31.Nxg5!
But after
31…hxg5 32.Bxg5!
it is the queen who is trapped.
