1. S's dbl on 3♥ would not be reasonable, since he can not dbl a 4♣ or even a 4♦ bid. 2. Yes, I believe that W should be allowed to rescue in 4♣. Even if E is sigl there, a 6-1 fit is better than a 5-1. 3. I don't accept Ws assertion that he would rdbl to show SOS. Why this should not show a max support in ♥? Why would not he bid 4♣ to show both minors? 4. It is obvious that EW missunderstanding should be punished acording to the rules of wrong expanation. For me is also obvious that score (-3 undoubled) stands.
