So here's what happened at the table:
I decided that the hesitation might imply that partner has spades, so I shouldn't lead the
♠A. I'm not personally a believer in leading away from kings especially at MP scoring against a suit contract. So I decided to go passive and lead the club 3 (3/5 leads). Partner's hand turned out to be:
Partner ruffed the opening club lead and thought for a while. Deciding to read my
♣3 as suit preference (which it wasn't) he underlead the diamond ace back to my king (despite dummy's singleton) and I gave him another ruff. Then a spade was lead back to my ace and the hand was over, down one.
The opponents were a well-known pro-client pair who have won multiple national championships. They called the director here and suggested that "partner must've been thinking about doubling 4
♥, which would ask for a club lead" and that therefore I should not be permitted to lead a club. I felt this was dubious at best, since a double would probably just be "penalty" and if I was trying to give a ruff I would probably lead a diamond in any case. It was particularly annoying since
without the UI I would probably have lead the
♠A on this auction (which
also leads to a one-trick set fairly easily, since our obvious shift signalling methods make it easy for partner to request a club switch). I had chosen to lead a club
specifically because I thought partner's hesitation suggested a spade lead and then had my club lead rolled back. In any case the director changed the result to 4
♥=, which was actually an average-plus for us since many people were making five on the hand for some reason. Partner and I chose not to appeal, in part because we were relative unknowns playing against famous elite players, and in part because we were above average on the board in any case (and were afraid committee would further alter the result to 4
♥+1, which seemed to be fairly common in the field).
In any case, I think UI problems on opening lead are particularly difficult to resolve, because you rarely get much agreement on what to lead (on this problem three of the four suits seem to have roughly equal following) and there's a sensible argument for
almost anything to be "suggested" by the UI. I was curious what others would think about this ruling and situation.
