I suggest you try the option to see its effect! :P I have no doubt it is easy to detect when some player has it on. (Thus it also informs about the absence of singletons!) About the UI issue, here are two examples among many of the same kind: - Declarer holds KJxxx and dummy Axxx in some suit. He cashes the Ace first, but when doing this he can see his LHO had a singleton: "easy" and not fair to try the Q finesse then... - As a defender you win a trick led by the declarer, but you could see/detect your partner's remaining singleton. Then you know he may ruff your return in that suit... To solve this problem and those related to the playing and bidding tempos (still allowing the auto-play option for convenience), I would suggest that: 1) no card could appear to be played in less than 1 seconde at the table 2) no bid could appear to be made in less than, say, 2 or 3 secondes (for instance fast passes or doubles are sometimes meaningful I think) Of course every BBO game is not a world championship, but I believe it would improve the game fairness. -- Bruno
