Game from Gene Hackman Movie Night Moves

This game is Emmrich-Moritz, Bad Oyenhaussen 1922.   Harry Moseby, Gene Hackman's character, ponders how Black missed the win with 26...Qxh2+  27. Kxh2 Ng4+ 28. Kg1  Nh3+  29. Kf1  Nh2#.  The alternate outcome is presented as #204 in Reinfeld's 1001 Brilliant Ways to Checkmate, and on this site as Tactics Training problem #0026289.  When this one came up in Tactics Training I recognized it but too slowly, getting -7 for getting it right.
