But experts don't always have it their own way. Sometimes, there will be one obvious action which I'd expect most bridge players to choose; it would be the only logical alternative for an intermediate player. But an expert could think of an extra possibility, maybe a bid which can't logically be natural in the context of what (s)he believes the auction to mean. Now suppose that the expert has UI from an unexpected alert/explanation. Now the expert may be ethically obliged to make the "can't logically be natural" bid which is less likely to clear up the misunderstanding (s)he has discovered through UI.

 

In my experience, the rules aren't enforced this way. You're not allowed to make a 'creative' bid in a situation where you think the 'normal' bid is suggested by the UI because if it works, you will be ruled against. UI rulings basically amount to "if pass is one of the logical alternatives then you must pass". I've never seen a player penalized for passing in a marginal situation where an expert player would surmise that the UI probably suggested taking an action.

Interesting, I would not consider this double as obvious as others do. In the end I would double, mostly on the theory that defending two of a major at matchpoints usually stinks anyway. But I definitely consider pass, and probably tank long enough to give more UI back to partner http://www.bridgebase.com/forums/public/style_emoticons/default/sad.gif
