Re: Copenhagen Hnefatafl

Good example Hagbard - this is a repetitive situation which nevertheless features not very much repetition in the actual moves. Classic situation where an umpire could judge straight away that it was a draw situation, but a computer couldn't. But is it repetitive check? I'm beginning to realise (I'm...

What will white's next four moves be?
Black's next three moves will be forced, but on the fourth one, there is a choice - what is the best fourth move for black, to prevent disaster?

Re: Copenhagen Hnefatafl

double perpetual check.JPG Even simpler. Each player is creating check every other move. Which one is the "offensive" one? Since this is unclear, the situation would have to be declared a draw.

double perpetual check.JPG
White moves c9 - c11 check,
black moves b9 - b11
white moves c11 - c9
black moves b11 - b9 check

Each player is repeatedly putting the other in check.

If no offensive player can be determined, the game is a draw. to the tournament? There has been no need for it yet, but I'm sure there w...
