My Favourite Jan Timman 2

Pin It My Favourite Jan Timman 2

Queen's Indian Defence.

Romanishin -- Timman
Taxco 1985

1 d4 Nf6 2 c4 e6 3 Nf3 b6 4 g3 Ba6 5 Nbd2 Bb4 6 Qc2 Bb7 7 Bq2 Be4


A well-known manoeuvre. Black increases his influence in the centre before giving up one of his bishops.

8 Qb3 Bd2 9 Bd2 0-0 10 0-0 d6 11 Qa3

A remarkable move. White invites the advance of the Black a-pawn in order to strengthen his own c5 advance when time is ripe.

11 ...Nbd7 12 Rac1 Qe7 13 Rfd1 Rfe8

This protects the queen, which can be important at times, Black has refrained from advancing his a-pawn for three moves, chiefly because he may wish to play ...c5 himself and would therefore want to keep his pawn formation flexible. Romanishin feels that the time has now come to take the initiative on the queenside.

14 b4 e5

The correct action. Without the b2-b4 advance, e6-e5 would be answered with d4-d5 , After Black would face space problems. Now 15 d5 is not so good because of 15 ... b5! 16 cb5 Nb6 when Black gets a hold on the position. therefore White decides on a different advance.

15  c5 ! dc5 

The best reaction. White would obtain a clear positional advantage aftrer 15 ...ed4 16 cd6 cd6 17 Bf4

16 dc5 bc5 17 bc5 h6

A useful move in almost every way. White's minor pieces cannot now use g5.

Ba5?

Romanishin overlooks Black's positional threat 18 Bc3 was better in order to keep the enemy position under pressure. After that Black could best defend by playing 18 ...Bd5, followed by 19...c6.






18 Nb8! The knight is heading for its ideal square, c6.

19 Bc3 Nc6 20 Qa4 Qe6

The purpose of Black's 17th move becomes apparent - White's Knight cannot enter, and attack from g5. Black is already slightly better.

21 h3 Rad8 22 Ba1 Bd5 23 e3 Rd7 24 g4

Obviously with the intention of further advancing that pawn.

24 ... Red8  25 Re1 Rb8


25 ...Ne4 was the alternative, taking advantage of the fact that white would lose the exchange after 26 Ne5 Ne5 27 Be4 Be4 28 Qe4 Nd3. However after 26 Rc2!  the situation is less clear. Then the strategical exchange manoeuvre, 26...Ng5 does not work because of 27 Ng5 hg5 28 e4, when White wins material.

26 Bc3  Rdd8

Again there were tactical disadvantages to 26...Ne4, this time due to 27 Be5. Black can try 27...Nf2, but during the game I did not like the response 28 e4!






It was discovered during the post-mortem that this complicated situation would resolve itself into a forced draw after 28 ...Ne5 29 Ne5 Qe5 30 ed5 Qg3 31 Qd7 Nh3 32 Kh1 Nf2 The text move paves the way for ...Ne4.
