TWO QUESTIONS
Q1) Is East constrained from bidding 2♠ after East's hesitation?
Q2 How do you do rule?
Q1) Is East constrained from bidding 2♠ after East's hesitation?
Q2 How do you do rule?
Q1. Of course East is constrained because he has UI and Law 73C requires him to take no advantage.
Q2. No adjustment, of course.
The interesting question is not whether I adjust for 2♠, but whether I adjust if he passes. 2♠ is a pre-empt, and the UI that partner has near opening bid values suggests not pre-empting.
I poll, of course, and if enough people bid 2♠ then I adjust if he passes to whatever would happen if he bid 2♠.
An interesting example of "If it hesitates, shoot it." It is so easy to forget to ask what the UI shows.
