Can you identify this game with a mate in 12? I vaguely remember it being from a game played in the USSR ca. 1960.  I'm certain it was from before 1985.

I can't find the actual game neither in my database nor at, say, chessgames.com. However, the position appears as puzzle 210 -- with the apt description &quot;Running around like a squirrel in a cage&quot; -- in the book 1000 Checkmate Combinations by Victor Henkin, and there it is attributed to a game Aleksandrov-Zaitsev 1974.
