Very hard puzzle - first solver gets a trophy!

Should the moves make sense, or is it allowed to do moves that would not be good if you would try to win the game?

Yeah, i know that one ;)

IM Klaus Berg showed that one, and one more at the same kind, at a chesscamp this summer :) Klaus told us, that his friend GM Nigel Short showed him them.

This is a very beautiful puzzle!

The only way is if Black is giving d-pawn odds.

i figured it out after some experimenting

We have a winner!

Haha, I'm going to show that to someone, some day.. :D

Why doesn't that work?

ok now I feel stupid, lol sweet puzzle!

Because black 4th move have to be done to. In your way, black has only done 3 moves.
As Kacparov said: "It's now white to play his 5th move"

That's a quick answer! And sorry, I didn't see that topic...

A semi reversed bongcloud opening ?

yes nick young, and just as in the regular bongcloud opening, the player who moved his king out first has a decisive advantage.
