Swiss teams, IMPs -> VPs
The auction was identical at both tables (different matches).
3♥ was a weak jump overcall.
Double was for penalties in both cases, but not alerted.
Table 1:
The defence started with three rounds of spades. North ruffed and led a diamond, expecting East to have length in the minors. East took the ace and gave his partner a diamond ruff. North ended up four off, -800. (I'm not sure how he managed to go four off - he said he didn't lose a club trick.) North called me at the end of play to say that had he been alerted to the fact that it was a penalty double he might have taken two rounds of hearts first, preventing the ruff.
Table 2:
I believe North went two off. NS called me at the end of the round. North had asked the meaning of the double before the opening lead (according to NS) or either before the opening lead or before the final pass of the auction (EW couldn't remember which), and was told it was for penalties. South claims she would have bid 4♦ had she known this earlier.
Would you award an adjusted score in either case?
