"Black effects the decisive combination out of order. Because of counter combination which will be possible in the 30th move Black is forced to long struggle. The right order of moves here is: 27… Nxg3! [as shown in the database game] 28.Kxg3. – More unpleasant is 28.Rxf8+ Rxf8 29.Kxg3 Nxe4+. – Rxf1 29.Qxf1 Nxe4+ and later Rf8 with quick winning."
Geza Maroczy wrote a book in 1942: „I began in this way…” There he presented this game without analyzing, only he analyzed his bad 27th move, but he reminisced about Owen: „Rev. John Owen fell for my play at once, and he looked for the play with me after the tournament as well. We had played two match-games, I hadn’t have more time. Both of games were in completely irregular outcome, and in those I succeded surpass him…. John Owen declared that since a match with Paul Morphy nobody did defeat him such a manner as Maróczy have done it! It was such apprecation which I could have understand properly after studying of Morphy’s games.”
... as I understand the DB game isn't the real deal, or am I wrong?
