Hennns got it!
I have to admit I had to peek at the solution to Trilussa's problem. It's very nice :)

Does Trilussa have a unsvolved problem? (I didn`t bother reading all the posts)

I don`t get how to post pics so I`ll give you a link, just copy it and then past in the browser. (if you can`t just click it) BLACK to move, wacth out it`s hard ;)

Oh dear...

Just use img /img with those brackets []

The link messed up the forum a bit, too bad there is no edit button :(

to 10 Nxd5 Qxh2
11 Nc7 Kd8
12 Rc1 Kxc7 ==> pieces advantage

Thanks szeweningen, I`ll try that next time..:)

Ok here is the solution to my puzzle:
Nb6+ Kb8
Rc3 Pawn promotion
Nd7+ Ka7
Ra3+ Kb7
Rb3+ Qxb3
Nc5+ 1-0

No ideas for my problem?
Here are some tips:
1. You (black) will sacerfice something
2. Find whites most importent/best pice AND a way to remove it

hennns, do you sac the knight on H2 and then Queen to h4 to regain material? I cannot see the whole solution but I dont think black has anything but ...Ng4

1. ... Ng4 2. Bxh7+ with Qh3 makes me worried...

I also don't see it, I'd just play 1. ... Qh4 with threat of fork Qg4, but white can just respond with 2.Rxd7 Qxe4 with a nice positional advantage for black due to whites bad bishop and weak king's position , but I don't see more... I certainly can't see a win or a big enough advantage to declare a win.

2.Bxh7+ KxH7
3.Qh3 Nh6

looks great for black, no?

Ok, then just 1. ... Ng4 2. Qh3 threatening Qxh7#, forces Nh6...

Ng4 is wrong, and I`ll give you a couple of hints more.
3. Find BLACKs worst pice.
4. It`s not a combination, it`s a positional problem.

5. whites best/most important pice is the bishop on e4.

I`ll post the sulution if novone comes up whit it in a reasonble time.

Ok, the solution is...1...c5!

First to say why will post next puzzle, and I have to confirm that the reason is correct.

dont have time to analyse it, but 1)... - f5 is tempting

Complete sulution:

1... c5!
2. Bxb7 Bc8!!

Now black exchanges bishop no matter what white do and the game is (practically) won due to the weakness around whits King.
I`ll leave the next problem/puzzle tho whoever post one first.

Henns, what is your reply on
1. ... c5!?
2. Qd3

2... Bb6
The h-pawn don`t really matter.

Well, both me and Fritz think otherwise... all the engines I have recommend just a slow positional 1. Nf5 and signal a better position for white after 1. ... c5!? 2. Qd3 Bb6 3. Bxh7+ I definitely do not see that huge positinal gain that'd compensate the pawn, but maybe better players should comment on that.

Very nice Hennns. Is this from a real game?
Szeweningen you need to get Houdini, version 1.5 is still free to download. It does in fact give the nod to 1...c5! It should be noted that Black was a pawn up in the starting position so giving it back to eliminate White's bishop pair and get good knight vs. bad bishop is logical. Also it fixes b3 as a weakness and eliminates the best defender of White's airy kingside while Black has no weaknesses at all.
Something less Dvoretsky-ish... I posted this one earlier so I'll bring it up again:

White to play and draw
