Comments.Text: Not to nitpick, but it's appears to be mate in 12 rather than 10. By the way, are you certain that's the exact position from the game you have in mind?

  I can't find the actual game neither in my database nor at, say, [chessgames.com](http://www.chessgames.com/). However, the position [appears as puzzle 210](https://books.google.com/books?id=_ZekAgAAQBAJ&pg=SL6-PA47&lpg=SL6-PA47&dq=aleksandrov%20zaitsev%201974&source=bl&ots=p3_rNbjwmN&sig=25rzaRIVsENM2oSHR67qdP4I-Vc&hl=en&sa=X&ei=aBf1VPCTMIqlNtXNg9gI&ved=0CCEQ6AEwAA#v=onepage&q=aleksandrov%20zaitsev%201974&f=false) -- with the apt description "Running around like a squirrel in a cage" -- in the book *1000 Checkmate Combinations* by Victor Henkin, and there it is attributed to a game Aleksandrov-Zaitsev 1974.
