But a pleasant surprise for this spectator!

  Honza Cervenka: Instead of 28...Rg4+(?) black could have played 28...Rxf1 with idea 29.Bxe6+ Rf7 30.Rf1 Nf6 31.exf6 Re8 32.Bxc4 Nb5 33.Bb4 g6 etc. White is definitely better here but black is still alive with at least some practical chances to save the game.

  Honza Cervenka: If 19...Nxc3, then 20.f5 gives white clear advantage.
