First to post... :-)

I must admit that I find this one rather uninstructive

First post and it took me 10 seconds! Wooot!

Why do we have to move for black?

With White to move it would be pretty easy, too: 1.Nc6+-, but even if he doesn't play this, he's a piece up.

Black is a piece down in the initial position and needs to regain it, which he does by the combination given in the solution, so in the end he remains a pawn up and with the better minor piece.

So I should perhaps relativate my comment about its instructiveness: this sort of thing can happen quite commonly in a game, but from a puzzle I would have expected something else than just dumbly exchanging off the pieces and taking the hanging one last.

Wow, got this one on my first try.

Simple. I don't see any other variations that need calculating. Its all forced I think.

 I'm with you.  This just seems like common sense, not really puzzle worthy.

very easy.

what happens next if the black bishop kills the white bishop? theres no checkmate anyway

this one wasn't very short at least.. but i want it to be longer!!!

ok!

Well, actually White does have a major deviation: 1...Rxc1 2.Nc6!? Rxd1+ 3.Bxd1 Qb7 (or 3...Bh6 4.Bxb6 Bxd2 5.Nxe7+) 4.Nxe7+ with Nxc8 to follow. Unless I have missed something vital, I would prefer this continuation to the line given in the solution.

You missed the white bishop on e3 taking the queen. 

EDIT - apologies, no you didn't! :)

Pretty basic game where black levels the pieces. The game of course is far from over but blacks pieces are now more active. Whites best defence to the Black Bishop is K-f2. (Not B x B, as Q x B+ followed by Q x eP threatening the Bishop and destroying Whites defence).

Not the best of puzzles we have had on here but lets face it, more games are won in the middle of a match than at the end!

very nice strong attack

Good stuff once again and nice play Torkil.

easier

 Well you didn't miss the white bishop on e3 taking the queen [tbxab posted too fast], and your variation for white equalises [the original solution leaves black a pawn up].

So, you have a point there - white can do better.

However, the point of the puzzle is to see fast in which order  to exchange so as not to be left a piece behind. Black should see your variation also, but once black has realised that the first move has to be RxR then it [luckily in this puzzle] works even if black misses (like i did)  your improvement of white's play.

I must say that this makes the puzzle somewhat flawed ...

 

Solution by Torkel leads to same LEVELLING THE PLAYING FIELD? RIGHT But simply forced moves sequence any way Didi not require innovative thinking
