Fortune favours the insane

In the collection of "how to get an early draw by repetition" games, the following game figures prominently. Played before Karpov became a world class player, Igor Zaitsev bravely sacrificed his queen, but had enough to force a draw by repetition on move 15. In fact there was an even earlier draw available,  starting with 6.Kxf7 7.Qh5+
Since then the game has been played multiple times, with all but 2 games ending in a draw (in my database anyway). Curiously, the 2 non drawn games follow an early recommendation of playing 10 ... Ne5+ 11.Rxe5 Be6 which was assessed unclear in the pre-computer era, but is simply better for Black according to Stockfish. However in the actual games it was one win for each colour, with the White winner being David Smerdon in 1999, after IM Stephen Solomon misplayed the attack on White's King.
