Tactical Motif XII: Opening/Closing Lanes

This is the last of our tactical motifs. We hope you enjoyed the overview.

Closing a lane can be useful to carry on an attack, it is also called interference ( fr: interception), as the goal is to intercept the defence. Opening a column/diagonal is a common motif where the attack gains intensity.

Let's look at one example of each kind.

Closing lines: White to play
Miles-Pritchett 1982

1.?

Miles played the fantastic 1.Be5!!

This moves covers b2 (X-Ray), while interfering with black defensive pieces. 1..R8e5 or 1..R2e5 lets 2Qg7#,
while 1..Be5 breaks the coordination between rooks : 2.Qe8 follows. In chess composition, this theme is called a Novotny.


Black resigned after 1.Be5!!





Opening lines: Alekhine-Borochov 1932
White to play and win

Alekhine played 1.Ne6!. While this moves closes the c8-h3 diagonal temporarily( interference again!), it also opens the g-column.

After 1..Be6, the genius ahead of his time played 2Qh7+!!, where 2..Kh7 3Rh3+ wins with check-mate following.

A great example of both concepts !











Exercise: White to play and win
Larsen-Matanovic, 1965

Tactical Motif X: ZwischenZug (In-Between Move)

A Zwischenzug ( From the german move signifying intermediary move ; fr: coup intermediaire) is the motif where you can insert a move ( often a check but not necessarily so) in between a sequence to alter the course of action.


Illustration: Analysis position from (Fischer-Taimanov 1971 (6))

White to play
Here 1.Rc1 would lead to 1..Rc8 and Black is ok. Instead, White would win by playing 1Re2+!, a intermediary check moving away the Black king from the c-pawn.
Now on 1..Kf5 2.Nd6+! wins with 3 c8=Q.

The continuation would be 1 Re2+ Kf6 2 Rc2 Rc8 3 Nd6! wins because taking on c7 leads to 4 Ne8+, forking the Rook on c7 and the king on f6.

The Zwischenzug is a very sharp weapon.






Exercise:
Kramnik-Topalov 2006 ( The actual move leading to the world championship crown for Kramnik!).

Black just played ..Rxc5 expecting 1Rc5 Kb6 regaining the Rook. This is a major blunder by Topalov in the rapid game deciding the worldchampionship match.

Kramnik-Topalov, 2006

1. White to play and win (the world title!)

Anand's tactics explained - First exercize

We will analyze a combination from the game Reinderman-Anand 1999 next.

Black to play and win

(Reinderman-Anand 1999 )

Solution & Hints given below

How to find the best move:

We notice that the White king is weak and under attack, as all squares around him are controlled by him. At the same time, the white knight is loose on d6 and Black would like to active his rook in h8. Anand managed to created a double attack by playing the elegant 1..Bg3!

Position after 1..Bg3!

Now 2 hg3 hg2+ 3 Kg1 Rh1 #.

and after 2gh3 Bd6! winning the knight, White resigned.
