This seemingly ordinary position is actually incredibly rich. Enjoy!

Essential is also the position of the white king after 3. Nd3 c4+! 4. Rxb6 cxd3 and promotion cannot be stopped.

Indeed, incredibly rich considering it was a game and not a composition!

Amazing that isn't a composition - first the rook sacrifice to remove both defenders of c3 and then ignoring the free rook on b6 (game is lost if taken).

Did you find this in the game or only in analysis afterwards?

@texaspete: I've found this position on the internet and I was amazed. Apparently it is well known (but still valuable. And yes it was an actual OTB game and black did think for a long time before performing that very risky sac). Look for "Ortueta vs Sanz 1933 Madrid" on your favorite search engine.

Thanks - it seems like it was part composition though the winning idea was the same http://timkr.home.xs4all.nl/chess/rxb2.htm

Yes, it's a version of the position that actually occurred in the game, probably created to make Rxb2 the only winning move. And the same move in almost the same position occurred two years earlier in the game Tylkowski - Wojciechowski, Poznan City Championship, 1931.
