- The aga rules, recently posted here, include this:
-
- >8) Illegal Moves: An illegal move is one violating the rules. If a
- >player makes an illegal move--such as moving twice in a row (i.e.,
- >before the opponent has made a response), attempting to play on an
- >occupied intersection, self-capture, or retaking a ko so as to repeat
- >the full board position, the player must take back his or her move (both
- >moves, if he or she moved twice in succession), it shall be treated as a
- >pass, and a pass stone exchanged.
- >
- >An illegal move must be noted as such by the opponent before he or she
- >makes his or her move. When a player moves, he or she is tacitly
- >accepting the opponent's previous move as valid. In particular, if it is
- >discovered that an earlier move by one of the players was illegal, the
- >game must nevertheless be continued as it stands unless both players
- >agree to restore the earlier board position and proceed from that point.
-
-
- That bit about "attempting to play on an occupied intersection" is amusing.
- Also, the bit about having to accept illegal moves once the next move has been
- made.
-
- Some situations I can think of:
-
- 1) Player carefully balances a stone on top of another one. If this isn't
- flagged by opponent before the next move, then rule 8 says the move
- "stands" (pun realized). But how do we score at the end ? One could
- think about a stone "capped" (again, pun realized) on top of either a
- friendly or an enemy stone.
-
- In general, this idea of having to accept illegal moves once the next
- move has been played opens up all kinds of bizarre situations.
-
- 2) Two adjacent black stones of a string have been sloppily played such that
- the left of the two is a bit to the left of the intersection, and the
- right one is a bit to the right, such that white manages to
- play a "cutting" move that looks like a real cut in the game of go
- even though the white stone isn't even on an intersection at all !
-
- Again, if black doesn't call this before the next move, the rule says
- the play stands. But how do we score the game ?
-
- I would suggest the rules be modified. I might suggest that the rule state
- that anytime during playing or scoring, if an illegal move is found such that
- the opponents can not agree on how to fix the board to make it legal, if the
- directory agrees that the move is illegal, the other player wins. If both
- sides have illegal moves, then the game is decided by NIGIRI (black player
- holds handful of stones, white player guesses EVEN or ODD, and wins game if
- guesses correctly).
