An opening trick :)

Here is an idea for those that like to play blitz chess.  If you play black then you might like this opening.  The reason why I say it might be better for blitz chess is because if white can't see the dangers of taking the e5 pawn (which might take him/her some time to think about) then he/she might fall for the trap.  :) 

What about 5. Ng4?

Nice, I like how it forces white back into their ranks to defend their own pieces, very aggressive ;).

This is the so - called Maroczy trap, a very known one. It's indeed very playable during fast chess, but not advisable though. If white just continues his development after 3 Nd4, he'll eventually get an advantage.

Yes nice one, I fell for it myself a while ago. Terrible way to go

 

If 5 Ng4 then 5...d5 looks good for black as it opens up black's bishop for an attack on the white knight and at the same time 5...d5 attacks the white bishop.  :)  White would be overloaded in the defense.  :)

This is also known as Kostic's Trap I believe. It is a nice one, I have tried it once in a game, but it didn't work out because white didn't play all the moves like in the trap, and I had only memorized the moves without trying variations.

 

5.Ng4 Qxg2 becomes rook+pawn for knight? or another trap Rg1 Nxf3+ maybe?
I dont know the variations so just guessing. after Nxf3+ comes Qxf3 Qxh1+ and then something like Qg6 to avoid fool's mate.

Bxf7+... would result in sacrificing pieces for messing up the structure.

I think it's mainly for quick games. Enough things to do about it.
But I'll try it, definately

[sorry, overlooked in the first line, incorrect]

Why it's very small?? I'll make a bigger one so I can easily look at it...

 

 

Broze, look at this!

Ah, the Blackburne shilling gambit or the "oh my god" trap

aka Blackburne Shilling Gambit, though not really a gambit since White will lose material if they take the e5 pawn. I've won a few with it, both in blitz and even turn-based chess. It shouldn't be played against strong opponents since, if they do anything other than 4.Nxe5, Black's game will be off to a shaky start. I've used it many times and White usually does not take the pawn (or even play 3.Bc4 for that matter). But they do sometimes and it's very fun for Black if so :)  I agree that it's worth trying though, and I really enjoy using it. It will definitely sharpen your play as it is challenging to create opportunities while defending if White doesn't bite.

I actually used this in a tournament once! It was a 60 min game and I was rated only 1200(only my 2nd tournament). My opponent was over 1700.  He had never seen it before and fell for it! I didn't win that game but I did destroy his Kside! I actually came very close to a win but just couldn't pull it off since I didn't know what to do in the middlegame!

Instead of 5) Nxf7 - Bxf7 could be a reply.

 

I might have seen this in Bill Wall’s collection of short games (I think it’s in the download section).

Bill Wall does indeed have an excellent page on the Blackburne-Shilling gambit, and there are many moves that don't work for white.  This game even showed up in the Luzhin Defense, where the child prodigy beats his father with it.  The safest/soundest reply is probably 4 NxNd4 where some of Bill Wall's variations win quickly and in my experience, it wins as well, Wall also discusses 4 0-0 and 4c3 http://www.geocities.com/SiliconValley/Lab/7378/shilling.htm but if you want to have fun, try 4Bxf7+. Lots of possibilities, but I beat ChessMaster 10 with it and it seems to win in other games on the web.  

http://www.chesslive.de/ has several.

Eric Shiller mentions a possibly sounder variation (sounder than 4Bxf7+ not sounder than 4NxNd4) and the only variation that encourages 4Ne5.

4 Nxe5 Qg5 5 Bxf7+ Ke7 6 O-O Qxe5 7 Bxg8 Rxg8 8 c3 in Unorthodox Chess Openings though he goes on to say after 8...Nc6 9 d4 he is not sure of the advantage.

that's why you never take the pawn in a speed game..

It could also be called the costage. Once I saw the words white can't take the pawn on e5 I knew instantly what the opening was. I use this sometimes.

I beat my school's chess teacher with this :)
