Quick, Fast, Legal Trap Checkmates

So I've just pulled off my first Proper legal mate with a Queen sacrifice and everything. I'm a little bit chuffed if I do say so myself... so anyway, I've decided to find some similar openings, if you know of any others with a similar "ethos" put 'em up.

Here's mine :) It's called the "Sea-Cadet Mate", I was trying for danish gambit, but this is closer to "Goring Gambit" (I think)

 The rest of these I found on wiki, but put it here 'cause it's easier to visualise

And finally a win for black

Most of these are the same. Here is a very quick checkmate (2 moves) that is legal but black always checkmates:

Possibly a silly question but why the castle? Just a precaution or are you avoiding something?

I fell for the fools mate recently in a variation of the sicilian as black... very embaressing.

The game I'm going for is the Danish Gambit, it's all about fast development for aggressive play/ control. Lot's of traps, very fun, If Black defends well however, he can be fine with two pawns up.

I want Black to take the pawn on b2, so I'll make as many moves as I tactically can without having to take it. Thats my general strategy when playing this game

Another possible line for the game could have been 8.Qb3, and if 8...Bxf3 (with the idea of breaking pawn structure) 9.Bxf7 leads to mate
