1.e4 e5 2.c3 - Interesting?

 This looks like an interesting line- not that I am going to start playing it, but it is good enough for discussion:

Doesn't seem ti be that interesting... judjing from the popularity

Black plays d5 because White played c3 and therefore can't play Nc3. It's the same as the Ponziani except without the pins that make that position playable for White. After exd5 Qxd5 Black seems to be slightly better already.

2...Nf6 is also good for Black.

Yes, c3 is a bad move. Black equalizes easily.

What?  How are you rated 1800 blitz

Maybe he's good at blitz..

I have a friend rated USCF 1800 who played this! I was amazed when I saw him do it. And I asked him and he said he always gets beaten out of the opening haha. I think he might have grown out of it though and started playing better stuff. And yeah, 2...d5 and 2...Nf6 are probably the best moves.

As I said, I am not planning to play this. I just thought it was interesting

what me?!

I didn't like either player's moves 2, 3, or 5, and then I disagreed with your evaluation after 7.h3 so it was just unexpected for me.

I know you're not saying this is the best opening or anything, so I added the smiley.

he is 1800 because of tactics,

2 d5 and black is fine.

Why do you disagree with my evaluation? White has a strong center, the bishop pair, and if you say that the king is not safe, then show  a line to prove a win for black. And this was only a suggestion. The position I meant for discussion was the one after 2.c3. An analysis of 2..Nf6:

How do you know if I am a good tactical player? how do you know that I am a bad positional player? Have you ever played me? All I did was suggest an opening to discuss that is in the opening books. Notice I never said that I thought that the opening was good. Why not discuss a few variations?

3...d5! and it's just a reversed Philidor. The extra tempo doesn't mean much in such a quiet position, so it's just equal or a bit better for Black.

Again, I am not saying this is a good opening. When I keep presenting lines I am just trying to analyze this.

It's just the c2 queen and knight on b1 are awkward and 7.h3 made some weakness.  If white gets to play another move or if instead he plays 7.d4 then I'd probably take white.

But e.g. 7...d5 8.ed Qxd5 9.d4 Ng6 and black's development is just so good... give white a few free moves and yeah, I'd definitely take white, but it's going to be hard getting all the pieces into the game.

In the 2nd diagram I'd expect something like 7.d4 or just 7.0-0.  7.Nf1 and 8.Be3 ensures no tactics on f2 but seems to unnecessarily waste time in the opening.

2.c3 is probably equal like someone said earlier... so IMO no problems, play it if you like the positions!

3rd diagram reminds me of ponzioni type stuff.  Those positions I'm not as comfortable in, but I'm sure they're very playable.

yes, probably 7.d4 is better. You write :In the 2nd diagram I'd expect something like 7.d4 or just 7.0-0.  7.Nf1 and 8.Be3 ensures no tactics on f2 but seems to unnecessarily waste time in the opening.   This is a common plan in opening's such as the Ruy Lopez. Can you show me a way that play can take advantage of this waste of time? Meanwhile, white gets control over the squares d5 and f5, and also exchanges a strong black piece.
