Everyone should learn this trap

There is a final mating sequence. Can you find it?

Wow Thats Nice, Informative

4...e5 and 5...f6 are bad

11. h4

That's exactly what it is @tpr... Certainly a variant.

Ok, so I have been asked to do a public study. The critical position is

10. Bxd5+, Kg6?!

Here's a bunch of winning lines, we have

11. Qg3+, and (iff) kf6, then

[where "iff" means if and only if]

12. Bg5+, kg6 forced,

13. Bxd8+, and neither kh5 or kh6 works as

14. Qg5#

But what if instead, we had

11. Qg3+, Kh5, then this variant continues with

12. Bf7+, g6 forced lines

13. Qe5+, kh4

14. h3, Qd1+

15. Kxd1, Bg4+

16. hxg4+, Kxg4,

With the beautiful f3#

@AFM-MasterOfChess there you go buddy and all without computer aid ;) All the trap needs is a name, but is a unique variant of the Damiano defense as @tpr pointed out.

Another variant of the trap

I cannot find checkmate of course. But it looks similar to some fried liver attack or damiano defence positions and seems to be winning.

wow i had a game so similar to this, but I went Bc5 before sacking the knight
