- The New Zealand rules state that a move consists of
- a) saying pass
- or b) playing a stone on an empty intersection which does not repeat a
- previous board position with the same person to play.
-
- This explicitly allow passing at any stage regardless of the state of kos.
- It also includes whose turn it is when considering repetition.
-
- The new (experimental) American rules are the same. In Chinese rules the turn
- is not considered but passing is allowed (as a declaration that the game is
- over). In Taiwanese rules the situation is complicated as repetitions are
- divided up into disturbing and fighting kos.
-
- As you are in Europe you are probably using Japanese rules which just define
- a simple ko. In the situation you describe (with 2 stones getting captured
- and the 1 stone being captured back) it is not considered a ko and no
- prohibitions apply.
-
- I hope this helps
