The Cochrane Gambit - Is it sound ?

This is the Cochrane Gambit. What do you think about it ? Is it sound ? Can I play this in 90 min + 30 sec Tournaments ? [ I'm rated 1250 ELO, 1450 National Rating. ] As a Petroff Player with Black, I think this can be hard for Black. Engine says about -0.25. What is your opinion ? 

anyone?

My guess is that it is not sound. For no other reason that it is a sac early in the game, and cannot really be prevented.

But, Black's King's is not cosy, I must say. In a short form of the game, I would be put off playing the Petrov on that account.

Probably not sound, but not as crazy as it first appears either. A good thing about it is that most of white's compensation for the knight is immediate. You get two pawns plus removing black's right to castle. I think it's a very good practical try for a win. But it plays a little differently from other gambits, in that you don't have a significant lead in devolpment (having given away your only developed piece) instead you have the potential of a very strong pawn center, and the you have a little extra time in the opening, as black will have to spend some moves putting his king back unto a more reasonable square.

No way it is playable in long games. Might be pretty good for blitz/bullet though, as black has to defend with high precision, and just doesn't have enough time to calculate everything.

I don't know if this opening is sound, but what I do know for sure is that it is COOL

As I said, I play Petroff Defence and worried about Cochrane. I'M 1450. IN THE NEXT TOURNAMENT, THE HIGHEST OPPONENT CAN BE 1699. So I'll play this. Even in 90+30, the opponent may not see this: 1. e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nxf7 Kxf7 5. d4 Nxe4 ( ? ) 6. Qh5+ g6 ( 6... Ke6 7.Qe5 + +- ) 7. Qd5+ +-.

Not sound but close enough that a good player can do something with it against another good player. I play it all the time because the Petroff is so so boring unless you do something drastic. In my opinion, this is the best non awful way of making a fun game.

Can 1500-1600 Petroff Players find that line in 90+30 ?

the engine suggests 6. Nc3 or Bc4+ after 5.d4 c5.

Stockfish 8

[ 1.e4 e5 2. Nf3 Nf6 3. Nxe5 d6 4. Nxf7 Kxf7 5. d4 c5 ]

another Opening Line with Nxf7 sac.

I saw a player playing the cochrane in a classical tournament and pretty much destroyed his opponent.
