I had 6 clubs, 5 spades,(holding both aces) Qx in hearts, diamond void. Partner and I had agreed spades as trumps and he bid 4NT (KCB). I responded 5H - 2 aces without King of spades. Should I have included my void as an 'ace'? He signed off in 5S but I raised to 6S hoping that he had the heart ace (which he did and the contract made). Had he had the diamond ace instead we would have lost 2 heart tricks off the top.
