West led the ten of spades and South won with the queen and played a club to the queen, then crossed to a diamond, West pitching the five of hearts (reverse attitude), and played a heart to the queen, West playing the two and East winning. East returned a spade, I think the seven, and South won and cashed a diamond, West throwing a club, and another diamond, West pitching a heart. Now South led the ten of diamonds, and West took perhaps a minute to pitch a spade, and on the last diamond, the nine of spades in tempo. East pitched a club and a spade. South exited with the club, placing West with K Jx - A at this stage, but West had the six of spades to cash, and declarer made exactly for 30%. 3NT+1 was about 75%.
South asked for a ruling, as he felt that West's tempo when he was down to just spades, the jack of hearts, and the ace of clubs, could have misled. West, when asked, stated he was considering discarding the jack of hearts, and the TD eventually, after consultation, ruled this was a demonstrable bridge reason. Do you agree? I have no idea whether they were playing Michaels cuebids, nor what East's carding would be. They were a first-time partnership.
IMO West may advance some nebulous "bridge reason" for his hesitation, but he could have known it was likely to fool South. South's play and interrogation of opponents may be imperfect -- but his play is well short of a SEWOG, and he did try to protect himself, so both sides should get the same score.
