This o-o-o# is *almost* good. I say *almost* because Ke7# would do the job less flashily [it is like underpromoting to rook knowing that the promoted rook/Queen will be immediately captured];  the more so because as was mentioned above in the actual game white resigned - this mate was  someone's annotation.

But then why do I say '*almost* good' rather than 'not good enough'? Because if only the white Q were at b4 (say) then o-o-o# would be *the* terminal move :)

that was a really exciting and enjoyable game, thanks for posting it

thanks for posting such an enjoyable game to watch. 

Thanks oginschile!

In truth, the mate never happened in this game. It has been published a few times as "the inevitable result" but I believe Prins resigned after black's 28th or 29th move.

Mr Day has commented on this in the www.chessgames.com chat on this game, and he gives full annotation to this game in the book "Learn from the Grandmasters". It is an excellent excellent game, one of those games I never tire of playing through.

Oooooh I'd love to deliver mate by castling. Sliick.
