'There have been many instances in history when an inspired cavalry charge disrupts the momentum of a battle,'writes Srinath Narayanan who thinks Tigran Petrosian is one of the greatest players of chess, ever. He dissects the play of the former world champion in the first of his planned series of 'tribute' to Iron Tigran. Enjoy.

Iron Tigran: Clash of the Cavalries!

"During tournament analysis sessions players all speak at once, but whenever Petrosian said anything, everyone would shut up and listen." – Yasser Seirawan

There is no doubt, at least not anymore, that Tigran Petrosian took chess understanding to a whole new level. Tigran was born on June 17, 1929, and passed away on August 13, 1984. He was a Soviet Armenian grandmaster, and World Chess Champion from 1963 to 1969.

Although he remains no more, his games continue to teach eager youngsters like me to play good chess. I also understand that many players simply cannot afford to hire a good coach, and besides, 'good coaches' themselves are quite rare these days. This article is for all my friends who are willing to learn and inch closer to chess mastery.

Welcome to the world of 'Tigran the Ninth'.

As a mark of respect, I will keep my words to the minimum in today's article and let the former world champion's moves do the talking.

Reshevsky-Petrosian, Candidates Zurich, 1953

Let us begin with a game from the famous Zurich Tournament 1953, the tournament book of which is considered an all-time classic (it was written by David Bronstein).

Let us first look at two important moments...

A very logical positional operation. Petrosian always strove to improve his pieces while trying to impede opponent from executing their plan.

Petrosian's famous exchange sac!

Tal: 'This purely positional sacrifice (a quiet move, without any checks or obvious threats!) made an indelible impression on me.' Let me explain the whole game to you:

Black's strategy!! This game had the exact same impression on me as it had on

Tal! It turns out that, even though a rook is supposedly stronger than a minor

piece, in this particular situation, it is not clear why the rooks are

necessarily stronger. Rooks need open lines to function at their full strength.

White has the f-file, with no tangible targets. Apart from this, the remaining

minor piece, the b2-bishop appears inept. Although technically a sacrifice, it

appears more of an exchange to what is White's best piece.} (25... Ra7 26. e6

Bucephalus—the horse of Alexander the Great

Tal-Petrosian, Soviet Ch. 1958

There have been many instances in history when an inspired cavalry charge disrupts the momentum of a battle. Here's another such example.

{[#]} 24... Rbd8 $5 {Petrosian says: 'White has a great positional advantage.

He effectively has an extra, protected passed pawn at d5, and in the endgame

it may play a decisive role. Black could have satisfied himself with passive

defence - ... Bd6, ... Nd7, ...f7-f6,...Rf7,... Bf8 and so on, but against

good play by White he would sooner or later have ended up in a difficult

position. And here I managed to devise a rather interesting plan of defence.'}

defence. The knight eyes d4, via f5 after the f5 pawn break.} 27. Qd3 Bd6 {

of course White is better, but Black pins his hopes on the f5 break and the

ensuing counter-chances. I believe the position to be tenable.}) 25. Qf3 Rd6

transformed. The bishop will stand unopposed on the a7-g1 diagonal, while the

knight is prepared to cut the rook on d1 from d3, thereby reducing the impact

of White's d5-paser as well. Again, h4-h5, a move that looked so tempting and

innocious, has clear consequences!} 39. d6 Nd3 40. Qg4 Ba7+ 41. Kh1 f5 $1 42.

With the help of past analysis and the useful tool of getting instant

evaluation of engine, it is abundantly clear that Black has a sizeable

advantage. Rejuvenated by the adjournment after 40 moves, Tal showed his

resourcefulness and salvaged a draw.} 1/2-1/2

So, what do we infer from the passage of this game?

Well, exchange sacrifice, yes. Or a simple cavalry exchange, highlighting the 'relative value of pieces' in different circumstances. The rooks aren't more useful than minor pieces in every single situation. As the wise in India have learned from their lessons, sometimes, camels with fire on their hump can trample a horde of war elephants! [Ed. Note: This reference will be elaborated upon in a future article.]

Moving on to more practical matters: Are these concepts useful in your tournament games? Oh, yes. In the last tournament that I played in—the Aeroflot Open 2017—I was able to use Petrosian's teachings in more than one ways. Here is one small example:

Ferenc Berkes-Srinath Narayanan

Decision point! What should Black play here? Decide between 15...Bxe5 and 15...Nxd4.

It was as if I could see the ninth world champion point me towards the right move! Luckily, I listened to him and...

My opponent avoided this move but the critical line that was a part of my calculations in this game was 16.Nc4 to which Black has to play 16...Qb4, when after 17.Bxa8, Black has full compensation. It was important to calculate this because, otherwise, Black will just suffer if I chose the alternative (as shown in the game)!
