JG27Pyth: Irving Chernev published an article with copious annotations of this game in the November 1935 Chess Life and Review (It is anthologized in "The Best of Chess Life and Review, Volume I, 1933-1960 ed. Pandolfini.)
Mr. Chernev's article begins: "The following game is, in the estimation of the writer, the most brilliant drawn game ever played, as well as one of the finest of chess masterpieces! Sparkling as this gem is, it needed the masterly annotations of Georg Marco to bring out its full beauty. So dazzling were its coruscations as to blind other eminent annotators--Dr. Tarrasch, Herr Emmerich, Bogolubov, Dr. Tartakover, etc. so that they placed exclamation points where question marks belonged! Historically, the game is important as being one of the first wherein Hypermodern principles are essayed, in this case an illustration of control of the centre squares, foregoing their occupation by pawns."
Some high points of the annotation:
8...d6 Chernev gives a mini-lesson on pawn play here, discussing why d6 is superior to d5 in this position.
16...Nxd2 Chernev likes this move, Tarrasch apparently didn't. The comments here are not analysis of the game but rather analysis of the analysis; fascinating and instructive.
Chernev goes crazy on this move. He hates it and gives a full typeset page of variation and counter-variation to back his point. For Chernev this is the critical move of the game. Setting up the brilliant....
30...Nd3 Let me summarize Chernevs full page of analysis of this move: OHHHhhh god why?!? LOL!
"It is remarkable that all of the annotators place an excalmation point after Nimzovich's 30th move, and none of them point out the winning line, or even suggest the first move! The critics include Dr. Tarrasch, Emmerich, Bogolubov, and Dr. Tartakover. The variations that follow are astonishingly beautiful."
(He gives the variations, which, I admit I haven't worked through... but what is "the winning move" anyway?
According to I.C. it's 30...Re2! and you have to admit -- that's a sexy move.
From there on all the exclamation points belong to Bernstein... 31!, 33! 37! 47!
