Hi,culmer.During yesterday's CLUE CHAIN you asked a protocol question that I neglected to answer properly. You asked if you could still play after being asked to provide a clue without having solved. I think you are in the same position as the opener of the game and the answer is 'yes'. It has also been asked if a person declaring a clue 'open' is back in play. I have looked back and an earlier intro said 'the slate is wiped clean' so again I think the anawer is 'yes'.
