frolind & AbigailII: ah thanks .. it was called the 'crawford rule' indeed .. i didnt remember .. but it made me think of cindy indeed ;)
i can understand why it is not allowed on the first game after a player is 1 point away from winning .. but why allow it again after that first game ? the advantage for the other player is still there
i wasnt favourite (less than 10 steps ahead on him after my turn and a lot of steps to go :)) when i offered the doubling at 1-2 .. but he accepted anyway .. i guessed he would as he was playing very defensive in his games as well .. he didnt dare the risk (although he was building a nice block just before my home .. so i saw some problems with that and think he was the favourite :))
so the rule was applied correctly it seems .. i just cant see the logic to allow the doubling on any subsequent games :)
