I'm not talking about the king's gambit .. I'm talking about what comes next to it when I give up my knight !

It's called a blunder.

Actually I'm in a very good position to win the game, wich is being trully weel disputed .. Latter on I'll post the complete game so you can comprove it !

Your opponent is not requred to play well after you blunder.

We live and learn, eh? I'm definitely gonna give it the odd run out at blitz.

I can't post the game right now because we haven't finished it yet .. But you will see how it allows me to take control of the game .. And my opponent is playing well and not making crushing mistakes nor something comparable to that ..

But like the site database show it tends to favor white xP

 There are plenty of other examples.

reminds me also of muzio. :)

It also reminds me of the Muzio Gambit in the King's Gambit. The Muzio goes like this and gives white a strong attack that's difficult to defend against.

First four brave souls.

p.s. Unrated, one day a move.... just for fun.

It seems to have a bit of a relation with the Muzio Gambit...other than that, no idea.

On another chess site database (chessgames.com) the statistics are even better for white after 1.e4 e5   2.f4 exf4   3.Nf3 g5   4.d4 g4   5.Bxf4 gxf3   6.Qxf3:

73.3% White wins
6.7% draw
20% black wins

But the sample is too small, only 15 games.

And I found no name for this opening, and no exclusive ECO code. It is classified as C37 - King Gambit Accepted.

It just seems that bringing a queen out so fast, without any other development or being able to catle, seems risky.

Here's a moving diagram of the game shown in post #11:

Ok, it has a name: Rosentreter Gambit

Many people have made similar comments about the Muzio or Halloween gambits, both of which involve Knight sacrifices.  It's easy to click through a diagram and 30 seconds later declare it worthless or unsound, it's quite another to prove it in a game against an experienced gambiteer.

Gonnosuke, the Baptist.

i would consider this position excellent for white. he has complete control over the centre, a developed piece, at least one pawn for the knight, and black has only two missing pawns.

the entire purpose of the kings gambit is sacrifice. while white may not have attacking chances at the moment, in two moves he can generate a powerful attack on f7, i.e. Bc4 then 0-0, and if black has played into it, maybe even Bxc7, winning the queen or the king.

i say this position is an all but totally sound sacrifice for what. besides, without dubious moves like this, chess would be a boring old man's game

 well said Sir, I have won twice against the Halloween on this site, I am 100% sure I would have lost in an OTB game.
