Fight for the central squares! Anto Guijarro - Harikrishna, Gibralter; 2016


As we all know, the primary struggle in chess is to control as many squares as possible, which will extend to control of areas; files and diagonals.  But, the most intriguing aspect is the control of center and center resolution in particular, which is like a childbirth.....has to happen at the appropriate time, not too early; not too late!

Whilst watching the games played in the current Gibralter tournament, I was particularly intrigued by the game played in the penultimate round between Guijarro - Hari.


This is the position after Hari's 12th move ......Nbd7.


This was also the position reached in a game played between Lajos Portisch - Gennadi Sosonko, Tilburg, 1984; with a little difference that they had played only 11 moves and White's Bishop was on d2 instead of c1!


Portisch took a different path to control the pivotal 'e5' and 'd4' squares in conjunction with the control of the light diagonal which crosses these two squares!

 This game is very interesting to see note how a moment of nap, in this regard, is enough to screw-up the game quickly! The game continued....

 12.Bf4 Re8; 13.Rc1

 This move threatens Nb5 which will be very unpleasant to meet up with.  

 13.....Nf8

 This is indirectly directed against Nb5; whilst manoeuvring the Knight to a better square 'e6' from where it can have its bearing on 'd4' and 'c5' squares.  13....c6 would lose control of the vital 'e4' square and though .....a6 is ok, the move played is more precise.

14.Bg5!

 Very interesting decision! Portisch quickly realises the futility of the Bishop on f4 and before the Knight lands on the 'e6' square, pounces on the 'f6' Knight which is a defender/controller of the light squares in the center!

 14.....Ne6; 15.Bf6 Bf6; 16.e3 c5; 17.Re1 Nc7

 This and the next move is aimed at destabilising that White Knight on e5 - always considered a nuisance by the opposition!

 18.f4 Be7; 19.Ne2 Bf8; 20.Qd2 Ne6

 The issue with 20.....f6 is that, it will drive the Knight to a right square and Black would struggle to keep the c5 square (with or without the pawn).

 21.dc5 Nc5

The piece positioning of Black is not conducive for hanging pawns.  But the move played allows White to place his other Knight too on a fine post in the center!  This indicates that Black's strategy has backfired a bit....which explains for the blunder that follows!

 22.Nd4 f6?? 

 Perhaps, 22....Nd4 would have kept Black afloat, though White's position may still be preferable.

 23.Ndc6!


.....and it was curtains for Black!

 Interestingly, in a somewhat similar position (below), Portisch adopted a similar strategy against Timman in Bugojno, 1986; and the game went...


22.Be5 Bc6; 23.Bf6 Bf6; 24.e3 g6; 25.Ne2 Qe7; 26.Nf4 Bb7; 27.Nh2! Bg7; 28.dc5 Rc5; 29.Rc5 Qc5; 30.h5

 Portisch plays on all fronts! A typical wing overture after determining the center.

 30.....g5; 31.Ne2 Nc7; 32.Nd4

 White Knights....one by one gets attracted by the f5-weakness!

 32.....Ne8; 33.Nf5 Nf6; 34.Rc1 Qb4; 35.Ng7 Kg7; 36.Qb2 Bc8;

 Comes a bit too late!  The pin on the long dark diagonal is fatal!

 37.Nf3 Qd6; 38.Nd4 Bd7; 39.

....and Portisch won the game subsequently.


Coming back to Hari's game, finally!



With the passage of years and sitting on the shoulders of those giants, a similar position from the same opening is viewed differently.

13.Bb2 Bf8; 14.f4 c5; 15.e3 cd4; 16.ed4 Ne4!? 17.Ne4 de4; 18.Qe2 Nf6; 19.g4

Hola! This modern position happened in a game player 44 years back!!  It was between Larry Evans - Bent Larsen in San Antonio where Larsen chose to play ....Nd5 in this position and won subsequently....but perhaps due to mistakes by Evans.

19....a5!? 20.g5 Ba6; 21.Qe3 Bf1; 22.Rf1 Nd7; 23.Be4 Ne5; 24.fe5 Rc8!?!

Was this a bluff or invitation!!?  Try walking without "crutches" in this position, interesting to analyse!



25.Rf7!!?  Almost looks crushing! 25....Kf7; 26.Qf3 Ke7 (of course 26....Kg8 loses to the conventional 27.Bh7!! etc) 27.Ba3 Rc5 (again any other move is mate - the Bishop on e4 is like a damocles sword....ready to behead Black's monarch!) 28.bc5 possibly here Qd4 check comes in handy and then recapture on c5 and possibly Black may still be holding!

But, this was definitely worth a try, over the board!

25.Bd3 Re7; 26.Qe4 g6; 27.h4 Bg7; 28.a4 Qd7! 29.Ba3 Re6!

Hari defends the position admirably!  The White Bishops are really hungry and ferocious!

30.Bb5 Qd8; 31.Bc4 Qd7

Black is trying to build a fortress.

32.Rf3 Rd8; 33.Be6 fe6; 34.Bd6 Bf8; 35.Bf8 Rf8; 36.Rf8 Kf8; 37.Kf2 Qd5!

The fortress is complete!  Black has enough weakness in the White's camp to keep the Queen not venture into his territory and a swap on "d5-square" would build a wall and prevent both Kings from crossing over to the enemy side!

38.Qe3 Ke8; 39.Qd3 Kd8; 40.Qc4 Kd7; 41.Qb5 Kc7; 42.Qc4 Kd7; 43.Qd5 ed5; 44.Kf3 Kf6; 45.Kg4 Ke6; 46.Kf4 Ke6; 47.Kg4 Ke7 Drawn

A fine defence by Hari and as I post this article, he seems to be doing fine for a play off for the first place!

Every one in this world, assume an identity - a condition which imposes further conditions - based on which humans act at every moment and do whatever they do, assuming a false certainty in a world which is full of chaos and where chaos rules order and..... perhaps, an order lies underneath the chaos!

Times Correspondent: " Why do good players lose ?" Answer (Tartakover): " The board is full of mistakes, waiting to be made "  As the saying goes, good positions do not lead to a win, rather good moves lead to a win ! To play good moves consistently is the supreme talent which only great players possess - you have only handful in the history of Chess! They too are not immune to mistakes....but commit them on very few occasions compared to others. It is something similar to this assumption: if in Tennis or Shuttle Badminton or in Table Tennis, if a player is capable of putting the ball (or shuttle cock) into the other side of the net, successfully returning it, then he would never lose. It never happens! So..... in Chess! Playing good moves consistently is almost imposible even for the greatest! Then comes the most intriguing question, What is a good move? It is hard to define a good move as it is highly subjective. Suffice to say, a move is good if it sufficiently c

Patterns in the art of Chess

Nature uses only longest threads to weave her patterns, so that each small piece of her fabric reveals the organisation of the entire tapestry - Richard Feynman This article springs from the passion exuded by a young kid - Sai Akhil Anand - and his quest for discovering patterns (and express them as wonderful paintings) in almost everything that he sees and comes across even in his tender age! His world revolves around Hemchand sequence (otherwise known as Fibonacci sequence ), Sierpenski triangle, Golden ratio, Fractals .... so on and so forth and his canvas encompasses a vast arena ......from the trail of snail on the floor to the trail a rocket leaves on the stratosphere! Patterns are wonderful and enhances creativity, as long as it is used like we use salt in our food - nothing more nothing less! Patterns act as catalyst in the process of understanding the art and showcasing it by enhancing the creativity of the artist in his or her own unique way!  " Our humanity rests upo
