Re: Repetition of moves: some dubious positions

1) If ignoring the white piece on c11 which would capture c6 so that the king escapes and wins, if c11 were not there, then white is entrapped and repeats c5-d5, blocked by black, and white loses. 3) Complex. The king attempts to enter the fort and is blocked. Black attempts to destroy the fort and ...

Re: Repetition of moves: some dubious positions

First situation: You succeeded in finding a case where the repetition is noone's fault, both sides are only doing forced moves, noone is driving this repetition. I think I was too quick with this one. It does not matter, what's on the other side, when a piece attempts to bypass its opponent's block...

Re: Repetition of moves: some dubious positions

The point is that you can always adapt the showcase example in order to set a non straightforward forced win for white, that white can claim not to see such that black is forced to break the repetition. Same thing for black by the way: he could argue that white is far from having lost even if the k...

Black to play. Black has a choice! He can block with the f10 pawn instead of the c7 pawn.
White wins this in a few moves.

Now consider the two following variations of the first situation:

White to play. White has a choice! He can capture the b5 pawn
White is surrounded and has lost in a few moves.

Re: Repetition of moves: some dubious positions

Third situation: This is a classic. The eternal check. The first pattern of repetition which we met in the old days of Fetlar, it cropped up all the time. White is driving this one, and if white keeps doing this repetition, then white loses by repetition. Of course in this case, if white stops the ...

Re: Repetition of moves: some dubious positions

Second situation: And what about black's choice? After all, all this requires some non straighforward reading. What if black d10-b10? after white b4-b11? Exactly. Black could let white capture the piece and then seal up the whole corner. The battle is in full swing, and this game has not reached a ...

Re: Repetition of moves: some dubious positions

First situation: White to play. White has no choice but to escape or the king is captured. But by doing so, he also threatens to reach the upper left corner. Then the only way for black to prevent white's win is to block. But by doing so, he threatens to capture the king. Then the only way for whit...

Re: Brandubh 7x7

I humbly think the rules should rather be slightly adapted to consider the small number of attackers compared to Tablut. For example, the particular case of squares arround the throne could be modified to allow sandwiched captures of the King with only 2 attackers instead of 3, like this: Rule 7a.p...

Re: Rule variant between "Old hnefatafl" and Copenhagen

About the repetition, when you write "forbidden", do you mean "forbidden for white"? The case of repetition is general, the same for all variants. Keeping rules simple, it is also the same for both colors. (Right now the enclosed-repetition is only mentioned for white, but it does not change anythi...
