How is this chess opening called? What's the trap called?

I lost a game yesterday with this chess trap where the opponent gave his queen away to eventually checkmate my king. I was playing white. We started with the italian game, I pinned his knight with my black bishop at g5 but pushed me away with the pawns. Here is a picture of how it looked like:

Then we moved h5 Nxg5, h6 Nxf7.. He took my bishop at g3, then I took his queen. Then I took his pawn with my h2 pawn, BIG mistake. I figured out I could have won the match if I had just moved h3 instead. He would have taken my rooks but that's it, I still had the queen. What is that chess trap called? He said he read about that trap, but I still think I could have gotten away from it.

Can you post a link to the actual game, I don't understand your moves after the diagram.  Specifically h5 and h6.  Did you mean Rh6?  Either way you should post the game

OK, so here is a simulation of the game:

I think I still had chance to win after taking his queen, but several of my mistakes costed me that match.

Interesting, I don't know what it is called, but then again I am not very good myself.  After 13. h3 then you have Ne2+, then you will have to give the queen back otherwise it will be mate in 2.  I don't see a way to keep the queen.

hi lcruz

the opening is a Giuco Piano or the Italian Game.

You fell for an old trick in this line, known since the 1800s! It is unwise to castle and play Bg5 before your opponent has castled because he can whip up an attack. Here is a classic example:


[Site "St. Petersburg"]
[Date "1874.??.??"]
[Round "?"]
[White "Victor Knorre"]
[Black "Mikhail Chigorin"]

1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.0-0 Nf6 5.d3 d6 6.Bg5 h6 7.Bh4 g5 8.Bg3 h5 9.Nxg5 h4 10.Nxf7 hxg3 11.Nxd8 Bg4 12.Qd2 Nd4 13.Nc3 Nf3+ 14.gxf3 Bxf3
0-1

White is lost after taking Black's Queen, there is no salvation.

The whole variation is known since Dubois- Steinitz, London 1862 (which is 150 years ago).

According to the old rules from Lasker's Chess Manual, on double e-pawn openings white should NOT play Bg5 before Black has castled, more so if he has already castled himself. This rule does not always apply, but here is a very characteristic application of that rule.

Hmm interesting, thanks for replying. Very informative, thanks! 

So the whole idea is to castle after black has castled?

No, not really.

The main idea is not pinning the f6 knight before Black has castled. But of course you can postpone castling in favour of c3, Bb3, Nc3 or even Nbd2.
