Would you trump your partner's Ace ? Is it ever correct to do so?

This hand from the Junior Camrose 2012 saw West lead his singleton heart won by East with the King. East cashed a second winning Heart and West threw a low club to discourage Clubs. Now the hand blew up when East tried to play another Heart. Declarer was able to ruff high and then draw trumps ending in dummy with the ¨9 after the second round and run all dummy’s winning Hearts declarer making 5¨ doubled. Poor West wanted a Heart switch ? How could he tell his partner ?

He didn’t need to tell him, if he had the lead himself, as he would be able to cash the Ace and take it one off. How does he achieve this ? If he wants to make sure the contract goes off he MUST TRUMP HIS PARTNER’S ©ACE and cash the setting trick, ªAce, ( – now there will be no misunderstandings as he has made it easy for partner. (and himself).
