The worst puzzle ever.

After wasting my time with the puzzles, I have come to a conclusion: They are mostly terrible.

But I shouldn't be the only one with the pleasure to leave snarky comments on them. So, let's play a game everyone: every time you find a particularly bad puzzle there, post it on this topic. Let's see if we can find the WORST puzzle of the website.

My starting candidate is this one. Just look at the analysis, and you will see why.

So the biggest complaint that you have is that at the end of the puzzle white sacked a knight which you can recapture for free, which is actually the engines best move ( http://i.imgur.com/NECqhSW.png )?

That's really quite an asinine complaint when you consider capturing the trapped rook is the important part of the puzzle. The free knight is just a bonus.
There are some not-great puzzles on the site - same as on other sites I've seen. That particular candidate seems an odd one to choose as an example of the worst puzzle on the site - it looks absolutely fine to me.
When I have Stockfish lv 9 analyze the puzzle, it clearly marks the knight sack as a gratuitous blunder, with the recommended move being Bg7. Loosing that knight accomplishes absolutely nothing except give White a +8,7 advantage from +2 due to letting the white knight attack the black pawns freely, and the black knight is well where it is for the moment.

THAT is why I consider this puzzle the worst of the website by a large amount. And by the way, the idea was that YOU post the ones you consider particularly bad.
@SJMistery if you let analysis run long enough you'll see that the move played is not bad, and other move have worse evaluation. You need to give time to the machine
I did. An hour or two, Bg7 is still the recommended move.
I cannot discuss anymore since I have such a different experience with the engine. I hope you're being honest.

I have +14 for 35... Nxf5 and +17 for Bg7, that is answered nicely with Bxh6 Rxh2+ Rxh2 or doom on the edge, is not even in the top 3 choices anymore at depth 30 with houdini 8.

Can anyone back up his/her claim?

EDIT although the problem would not really be affected either way, because you did not have to CHOOSE Nxf5 as best move, but just answer with the proper response, i.e. recapture the knight!
