Paul I agree in this case the board could not be played Law12C must be used and an adjusted score be given. law12C2: Assigned score: When the td awards and assigned score in place of a result directly obtained after an irregularity, the score is, for a non offending side, the most favorable result that was likely had the irregularity not occured or, for an offending side, the most unfavorable result that was at all possible. If the irregularity had not occured EW would not play 4H, is the TD within their rights giving an adjusted score of 4H? being the most favorable for the non offending side or must they consider only most favorable result of 3S by South?
