[Retros] Chessbase 1999

[per olin]

Dear retrofans,

It seems that the undead inventor is modest in referring to his own achievements. There is a lot of interesting material about dead reckoning here http://anselan.com/chess.html

In Tehtäväniekka 4-5/2012 there was a very economical problem by Unto Heinonen: Kh6 Dg6 pawnh5 - Kh8 Dg4 with the four stipulations 1#, 1=, s#1, s=1. Is the fourth, selfstalemate in one move, incorrect for not being a stalemate after 1.Dg8 K/Dxg8, but dead reckoning after 0.5 moves? 

Cheers Andrew! and best wishes

Per
