I remember seeing a particular chess problem awhile ago on YouTube, but I can't find it. The problem's theme was something about caging in the Turkish king, and the video mentioned it as being old.
Regarding details of the problem, here are two. It ends in a smothered mate with eight black pawns surrounding the Black king. In the course of the solution, all of the Black pawns are forced into place by White.
Here is example I've made of the general concept.
[FEN "8/2pKN3/Q3ppp1/2ppk1p1/4pR2/3P1P2/4N3/8 w KQkq - 0 1"] 1. Qd6+ cxd6 2. Rf5+ gxf5 3. d4+ cxd4 4. f4+ gxf4 5. Ng6#
Does anyone know the problem and its source?
