As I recall, it was an almost dead-equal rook endgame with a single open
file, but capablanca had the slight advantage of having his king closer to
the open file. This seemed to make all the difference that he needed to
win. I want to say Capablanca had black. I also want to say this was
against Corzo, but I've looked at all the capa-corzo games I have and none
look familiar. And it may not be Corzo, so that may be a false lead.

I know it's not much to go on. If anyone recognizes this description --
especially the part about the smallest advantage of a better placed king --
I'd really appreciate a pointer in the right direction.

Sounds vaguely like Capablanca-Tartakower, New York 1924, though
there Capa's advantage rested more on having a rook on the 7th rank.
