Tigran L. Petrosian has the same name as the former World Champion, but his style is very different, as can be seen in our game of the day.

Tigran Petrosian, an Aremnian who was World Champion from 1963 to 1969, was known for his defensive prowess. His contemporary namesake, who is also from Armenia, takes after another ex-Champion, Mikhail Tal, who was known for his attacking abilities. In the following game, the modern Petrosian shows what he can do against one of his compatriots, Manuel Petrosyan, an international master. 

Petrosian, TL. vs. Petrosyan, M.
Mayors Cup Yerevan KO | Yerevan ARM | Round 1.1 | 31 Jan 2017 | ECO: A00 | 1-0
1. g3 This is not an aggressive first move, but it did not prevent White from launching an aggressive attack.
1... d5 2. Bg2 e6
2... e5 Of course there is nothing wrong with occupying the center.  )
3. d3 Nf6 4. Nd2 Be7 5. e4 c5 By an move transposition, the position is now a French King's Indian attack.
6. e5!? This is the extra option White has because of the unusual move order. Normally his knight is already on f3 and he cannot play f4 so easily as in this game.
6... Nfd7 7. f4!? Ambitious. I like this move.
7. Ngf3 The normal move does not work because White has not yet castled.
7... Nc6 And because White cannot play Re1, he would just lose a pawn.  )
7... h5?! This looks like a bad idea.
7... Nc6 8. Ngf3 b5 This would have been better. Black would develop his pieces first and then could castle on either side, depending on where White tried to attack.  )
8. c4! White attacks the center.
8... h4
8... d4 9. Ne4 And White would be much better.  )
9. Ne2 Nc6 10. O-O! Brave but strong. The open h-file is not too dangerous with a White bishop on g2 and no Black pieces able to attack at the moment.
10... hxg3 11. hxg3 Nb6?! This is very passive.
11... g5! This move would have created a lot more counterplay.
12. cxd5 exd5 13. Nf3 gxf4 14. Nxf4 Nf8! With an unclear position, though Black is probably not worse.  )
12. b3 The knight on b6 is poorly placed and Black has trouble developing.
12... f6? This causes more problems for Black's king than for White's.
12... Bd7 This doesn't look very comfortable for Black, but he is not doing that badly.  )
13. Nf3! fxe5 14. Nxe5 Nxe5 15. fxe5 Black is now in trouble as White is going to play Nf4.
15... g5 Black tries to stop the onslaught, but the punches keep coming.
16. Nc3
16. d4! This may have been even better, but I think that the move that was played was also quite good.
16... dxc4 17. bxc4 It's going to be hard to stop the queen from landing on g6.
17... Nxc4 18. Qc2  )
16... a6 A bad move, but it's hard to suggest anything else.
17. Qf3! The threat is Qf7. I don't think I've ever seen anyone get ripped to shreds this quickly after a quiet first move like 1. g3!
17... Rh7 18. Bxg5! The rest was agony for Black.
18... dxc4
18... Bxg5 19. Qf8+ Kd7 20. Qd6+ Ke8 21. Rf8#  )
19. Bxe7 Qd4+ 20. Rf2 Rxe7 21. dxc4 Qxe5 22. Qf8+ Kd7 23. Rd1+
