Tackling Petrov's defense (the Russian game)

I don't encounter Petrov's defense too often but when I do it always throws me a little of guard.  I don't know too much about it other than that it has a reputation for being drawish, so I would like a line in which I can shoot for a win.  Preferably it would also catch my opponents a little off guard, i.e. not really main lines.  Below are the lines I'm considering in no particular order, any thoughts or suggetions?

My preference is the last one. All White does is play Bf4, Qd2, 0-0-0 and attack the Kingside..pretty straightforward.

The first one looks unsound in my opinion.

#1 (the Cochrane) is crap.

#3 (the Nimzowitsch) will score you a few quick wins but I'm convinced that white gets nothing against a well-prepared opponent.

#2 (the Steinitz) is fine.

I do not think so, white gets 2 pawns for the piece, keep black king in the centre and get pawn roll. Notice that Topalov draw against Kramnik in this line at Linares '99 and it was a classic time control, not any blitz or rapid (http://www.chessgames.com/perl/chessgame?gid=1255554).

Original Cochrane (with 5.Bc4+ as the author used to play) was a crap. When Bronstein introduced the idea of 5.d4 and folllowing pawn storm with f4, e5 it appeared to be a playable line. Bronstein himself considered it not worse than 4.Nf3 or 3.d4

Petroff's folks might not be too prepared for the Halloween Gambit. I wrote about it here

IMO #1 is 'almost sound' so fine to play in blitz games or vs lower rated opponents who dont know you play it. I've had a lot of fun playing it but I would not play it against a strong player in an OTB tournament.

#3 was what Kasparov played and can lead to a lively game.

#2 is also good.

#1 Cochrane is almost sound indeed, but not really.
About 3 Nxe5 or 3 d4:
Carlsen could not prove any advantage against Caruana or Nepo with any variation.
Kasparov could not prove any advantage against Karpov.

I play a slightly offbeat line of the Steinitz.  White gets wrecked pawns, but he also gets a pretty big initiative.

1.e4 e5 2.Nf3 Nf6 3.d4 Nxe4 4.Bd3 d5 5.Ne5 Nd7 and now instead of 6.Nxd7, or the unsound Gambit 6.Nxf7?!, I play 7.Nc3!  After 7...Nxc3 8.bxc3 Nxe5 9.dxe5, White's pawns are a mess, but with moves like Rb1, O-O, Qf3 or Qh5, etc coming, White gets a raging attack.

I have played this twice in Correspondence (real correspondence, not the BS daily garbage here) against 2200-rated opponents, I have 1 win and 1 draw.

I'm fairly certain 6.Nxf7 is just a forced draw?

The stieniz is the best and nimzowitsch is also good and cochrane is a total crap

Here's how @Li-Bot dismantled me as white in the mainline: https://www.chess.com/game/computer/4402197

In my opinion the Nimzowitsch variation may be practically best. Here's a thematic game: https://www.chess.com/game/computer/4619769

And here's how black can avoid the Nimzowitsch (it's very rare I assure you Petrovers won't play like this). https://www.chess.com/game/live/41332167129

I did some research on this defence a while ago and I found a rare and somewhat confusing weapon for the petrov player, and one of Mikhail Tals favourite weapons against it: The Kaufman Attack: 

As a former petrov's player, the last option is certainly the easiest to play as white. The cochrane gambit is tricky, but most petrov players know how to refute it. The steinz attack is also fine, but it requires you to know more theory. The easiest position to play is the nimzo variation (the last one).

Yeah, come on, man! Just switch to d4 and play the London! e4 is disgustingly drawish, all you get is quick draws like this:

In comparison, the London System is by far the best opening in all of chess. It outranks all other classical openings, like the Ruy Lopez and Queen's Gambit. They're all terrible compared to the brilliant attacking ideas found in the London System. Honestly, why doesn't everyone just play the London? It's quite obviously superior to every other opening!

What are you talking about man? d4 scores more draw than e4 does. E4 tend to be way more unbalanced than d4.

In the last world championship how many games were won with e4 and how many ended up as draws?

Dude, you cant use one championship as a source. I'm talking millions of games from various databases and all suggest that d4 has more draws, less losses, and less wins.
