I met this possible position in the Scotch gambit. Is this playable?

I'd give Be3 a go.

Or b3.

Is there anything wrong with just a simple castles

5 cxd4 is better for white and clearly better than 5 Bc4

the position looks bad for white. I wonder why c3? Bc4 is much better I guess...

White is trying to play the goring gambit with c3 ... 

okay? But is this gambit a serious one?

I think that both black and white can play it better, but in the last position has white some chances I think.

Yes , at the amateur level its a serious gambit .

By definition, an ametuer is a person who doesn't play chess to earn money; merely only for fun and sometimes rating. Doesn't that make all us untiteld players amemtuers O.O

Also, thanks for al lthe feedback.

Thats what he meant.... Its only played at lower levels, not at GM or IM-level.

Lower levels can caover 0-2000 ratings, as most players in that range don't play chess for a living :P

The Belgrade Gambit with c3?  The Belgrade Gambit is 1. e4 e5 2. Nf3 Nc6 3. Nc3 Nf6 4. d4 exd4 5. Nd5!?...

To find out more about this specific line you should explore the Italian Game or Giuco Piano.

6.e5 is the newest attempt to revive the old Greco-Möller Attack, normally reached after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4, and has been championed by players like Leko, Ivanchuk, Jobava, Sveshnikov, Socko, Macieja etc. Reading these names I'd say the line is definitely playable at master level. After 6...d5 you should go for 7.Bb5 or 7.Be2!? instead of your 7.exf6?! though.

Btw, this is a standard "problem" with the Scotch Gambit: If Black so chooses you can't sensibly avoid the transposition into the Italian Game, like in the move order you posted.

Sorry , you are right , I meant the goring gambit .

Interesting. a player from a different chess site is playing the same line Greco-Mollor, I thought he made a mistake and he played the opening poorly. I have a large advantage already and I post this game after the game is over. Is the line Greco-Mollor any good?

Well yes, it is.

As has been mentioned these lines are quite old and established. The pure Möller attack 1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.c3 Nf6 5.d4 exd4 6.cxd4 Bb4+ 7.Nc3 Nxe4 8.0-0 Bxc3 9.d5 Bf6 scores pretty well for Black and is tough going for White. Occasionally 7.Bd2 is played, bit theory holds that Black at least has no problems reaching comfortable equality with 7...Bxd2+ 8.Nbxd2 d5. Therefore 6.e5 has moved into the focus of modern grandmasters and seems to hold up quite well.

Much more popular than the Greco is the Giuco Pianissimo 5.d3, where White postpones the d4 thrust to a point of time where he is fully developed. This is by far the most serious line for White in the Italian atm. Some enterprising players also try to revive the old Evans Gambit (4.b4), though with mixed results.
