Opening: Nimzowitsch-Larsen Attack, A01. 

| Brief summary. 
Note: Sources available suggest this is a correspondence game, confirmation has proved difficult. 
Early opening: Black chooses a counter fianchetto on the a1-h8 diagonal, a plan which usually ends with dark square bishops being exchanged in the middlegame. 
Mid opening: White takes the game into a double fianchetto system, the light square bishop on g2 needs to be treated carefully by black, or it will become difficult to restrain. At move 7 black might instead consider any of, pawn c5, Nc6, or, Re8. 
Late opening: White plans placing a knight on c4, where it restrains any advance of the black c-pawn, as the d6 pawn will be a target. This bind means black will struggle should the h1-a8 diagonal become open. 
Early middlegame: As dark square bishops and a pair of knights are exchanged off, it is the remaining white minor pieces who have much the better prospects. Check that long h1-a8 diagonal! 
Mid middlegame: The white queen and bishop control powerful diagonals pointing directly towards the somewhat lonely black king. Black struggles to find a means to counter them. 
Late middlegame: Take some time over the white moves, 22, and, 24. They set matters rolling for a fascinating and surprising squeeze. 
Endgame: The black king is on the edge of the board with few options. All other black pieces are immobile. Black is reduced to pawn moves while white just maintains the non-royal pieces exactly where they are. 
Resignation: Zugzwang! Black could have tried, 30. ... c3 31. a3, after which black must move a piece. Perhaps, 31. ... Rf5 32. Nxf5 gxf5 33. Be6, is simple for white. Instead white might consider, 32. g4 Rxf4+ 33. Kg3 Rd4 34. g5+ Kh5 35. Bf3+ Bg4 36. Nxg4 Rxg8 37. Nf6+ mate, a double discovered mate at that. ||
