I just saw this interesting puzzle on Chess Today. It is Black to move. How should Black proceed?

1… Nf3+ follwed by 2.g2xNf3, Be5. Black is forced to take the knight or lose the Queen.
But after Be5, doesn’t f4 stop the threat?
What about Qg4, threatening Nf3+?
Ah, nevermind. I my mind’s eye, I didn’t see that the doubled pawns block the rook from guarding f4. I think you’re right.
I missed Be5 and tried Bh6? instead.
Now reading that Be5 wins “too”, I tried to figure out a defense against Bh6.
1. -, Nf3+! 2.gxf3, Bh6? 3. Re3! and white survives.
Hmmm. Crap. 😉
This is straightforward.
1…Nf3+
2. gxf3 Be5
If 3. f4, then 3…Bxf4 and game over. An immediate f4 stops nothing.
So, 3. h3 is the only move, and then:
3. h3 Qxh3
4. f4 Qg4+
5. Kh1 Bxf4
6. Re3 Re5 is the end.
I don’t understand copyright law as it applies to subscription-media on the web?
Are you allowed to copy others’ Intellectual Property, available only on a subscription basis, to your own freely-accessible blog?
There is no copyright on chess position. She just took the position. OK to avoid any possible problem, she could just put the position in Fritz or any other chess GUI and post the picture on her blog. This is of course free (up to my knowledge)
You can find the full score of this charming game here.
The position is not copyrighted, but the diagram, ‘packaging’ around it (text), and the fact that ‘Chess Today’ finds it interesting are ‘copyright Chess_Today’.
I think the best advice I can give is that if this blog has a deal with ‘Chess Today’ to use its material in exchange for advertising ‘Chess Today’, it should say ‘Published with Permission’ to make it clear that it is not plagiarising.
