On 9 November 1944 the Grand Master Frank James Marshall died of a heart attack, collapsed while walking the streets of New York. 32 years earlier, in Breslau tournament, had won spectacularly against Stefan Lewitky playing with white.

This isn't really an endgame.

i remember this - spectacular move!

It's by far the best move in chess in my opinion. It's just absolutely awesome. All the pins, forks, and tricks involved in just one move is just spectacular!

It was for Levitsky

The gold coins weren't for Marshall, they were for the lucky gamblers who bet on Marshall to win - Lewitsky was a big favorite after beating Lasker and Rubinstein in the same tnmt. But maybe some of the winners "tipped" Marshall?

A wonderful brilliancy by a wonderfully brilliant player! And here's an echo of that brilliancy, by another great romantic of the chessboard
