This year Tigran Petrosian would have celebrated his 90th birthday. The Armenian grandmaster and world champion was noted for the profundity and originality of his strategic concepts, as well as his quasi-invincibility in high level contests. He was certainly my role model when I was a student of chess in my teens, a chess hero to emulate along with Aron Nimzowitsch, Richard Reti, Alexander Alekhine and Mikhail Botvinnik.

Gligoric elects to keep his bishops in an attempt to complicate matters. 29 Qg1 A remarkable defensive precaution I suspect only Petrosian could have conceived.

Now, however, the knight and rook weave a mating net. 43 Ng5 Bd3 44 Ra7 Bc4 45 Qd1 Black resigns An elegant finish, offering Black a choice of mates.
Petrosian inspires many an Armenian chess player to this day, including Levon Aronian, a regular world championship candidate. The Armenian team has won gold in the chess Olympiads on an astounding three occasions.
