Dec-23-07  whiteshark: <DarthStapler> Interesting! :D
Jun-02-08  jeeky1996: Interesting...Viktor Korchnoi nearly lost...but he drew by prepetual check. His opponenent's sacrifice of the queen allowed an attack of Viktor's king, maybe Viktor was just lucky!

  Check It Out: Wife's pun suggestions: Jurgen to draw; Jurgen to get it; Annie get Jurgen.

I'd like to spend a bit more time on whether 28 ... Qg4 29 Rb8+ is playable. Unfortunately the weekly visit to the supermarket beckons (yippee!).
