"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 generation to generation 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 a minimum in today's article and let the former world champion's moves do the talking.
Reshevsky-Petrosian, Candidates Zurich, 1953
Let's 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 the opponent from executing his 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 critical part of the game to you:

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 f6 27. Bf3 Ne7 28. a4 bxa4 29.

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.

Rejuvenated by the adjournment after 40 moves, Tal showed his resourcefulness and salvaged a draw. 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, a camel with a fire on it's hump can trample a horde of war elephants!} 1/2-1/2

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)!
