This board shows why it's not enough to say you are playing UDCA.
What signal do you expect here: count or attitude? If the latter, then we give partner a club ruff. if the former, then it's a guess. There's plenty of room for declarer to have, say, Kx AQxxxx x xxxx
Even if partner is giving count (not attitude) we don't know what to switch to: has declarer got xx AJxxxx Kxx xx or Kx AQxxxxx xx xx
What would 2S from partner have meant over the double?
At trick 1, you mean A♣ (agree?). Playing UDCA, P plays the 4. Now what?
