12. Forcing

In some situations you can force a combination. Before the combination takes place you play a move that forces your opponent to answer in a certain way. After this forced answer you can take a shot.

White attacks piece 20.

1.30 – 25!

Now black can only defend the attacked piece by playing the exchange with 18 – 23 25 x 14 19 x 10. After this white can perform a Coup Philippe.

1… 18 – 23

2.25 x 14 19 x 10

3.35 – 30! 24 x 35

4.44 – 40 35 x 44

5.43 – 39 44 x 33

6.38 x 7

White begins with a forcing move:

He attacks with 34 – 29, forcing black to play 14 – 20.

1.34 – 29! 14 – 20

2.26 – 21! 17 x 37

3.28 x 8 37 x 39

White has two free moves. He doesn’t go to king but uses the free moves to perform another combination:

4.50 – 45 2 x 13

5.45 – 40 24 x 33

6.40 – 34 39 x 30

7.35 x 2

In this example white plays two forcing moves before performing a Kung Fu shot.

1.39 – 34! 19 – 23*

2.34 – 30 13 – 19*

The * - sign means that a move is forced.

3.40 – 34! 29 x 40

4.35 x 44 24 x 35

5.44 – 40 35 x 44

6.43 – 39 44 x 33

7.38 x 7

Sometimes the opponent has more than one answer, but will always lose.

In this case black has no good answer after:

1.33 – 28!!

Investigate this position yourself!

.

White takes advantage of the gaps in black’s position.

1.44 – 39!

Threatening 28 – 23 19 x 28 33 x 31 W+1.

1… 27 – 31

2.37 – 32! 7 - 12

White was threatening 28 – 22 18 x 27 32 x 21 29 – 23 19 x 28 33 x 2.

2… 7 – 11 isn’t possible because of 32 – 27 31 x 22 28 x 6. After 7 – 12 however white will get a break through.

3.28 – 22 18 x 27

4.32 x 21 26 x 17

5.29 – 23 19 x 28

6.33 x 11

1.31 – 26! 22 x 31

2.36 x 27

White is threatening 26 – 21 17 x 26 37 – 31 26 x 28 33 x 4 while 2… 9 – 13 is punished by the coup Philippe 3.27 – 22 17 x 28 4.33 x 22 18 x 27 5.35 – 30 25 x 34 6.40 x 9.

So black should play 17 – 22 after which white performs a special trap shot.

2… 17 – 22

3.35 – 30 25 x 34

4.39 x 30 22 x 31

5.30 – 24 19 x 30

6.40 – 34 30 x 28

7.26 – 21 16 x 27

8.37 x 26 28 x 37

9.42 x 4

White is able to remove piece 13 and makes a shot using an opponents king.

1.27 – 21 8 – 12

2.33 – 29 24 x 33

3.38 x 18 13 x 22

4.37 – 31 26 x 37

5.42 x 31 17 x 37

6.48 – 42 37 x 48

7.30 – 25 48 x 30

8.35 x 4

White forces his opponent to play 14 – 19 after which piece 19 is transported to square 28 after which white is able to make the 27 – 22 shot.

1.49 – 43! 14 – 19

Black had to stop the 24 – 19 13 x 24 34 – 30 threat.

2.39 – 33 19 x 28

3.27 – 22 18 x 27

4.31 x 2

White forces a win in a very surprising way.

1.32 – 28!! 2 – 8

Other moves don’t help either.

1… 12 – 17 2.28 – 23 19 x 28 3.39 – 34 28 x 30 4.25 x 21 W+1

1…. 18 – 23 2.27 x 20 23 x34 3.42 – 38! 24 x 15 4.33 x 13 +

2.28 x 17 12 x 34

3.42 – 37! 29 x 38

4.40 x 9 13 x 4

5.37 – 32 38 x 27

6.31 x 2

Blacks position has some weaknesses. There are gaps at 12 and 13. White can force a king shot by attacking piece 27.

1.42 – 37! 7 – 12

2.37 – 32 11 – 16

3.32 x 21 16 x 27

4.26 – 21 17 x 37

5.48 – 42 37 x 48

6.39 – 34 48 x 30

7.35 x 4

1.33 – 29!

Because of the threat 27 – 22 black is obliged to reply making a planned sacrifice.

1…. 23 – 28

2.32 x 23 30 – 35

Black thought he was OK because of the threat 20 – 24. But white surprises his opponent.

3.34 – 30! 25 x 21

4.26 x 17 12 x 21

5.23 x 3

It looks silly at first sight but white’s next move forces a winning shot.

1.31 – 26!! 21 - 27

1… 18 – 22 is answered by 2.26 x 17 22 x 11 3.33 – 29! 13 – 18 4.29 – 24 19 x 30 5.28 x 10 15 x 4 6.34 x 25 W+1.
