BIDDING: Sitting South, after my partner raised
diamonds, I set spades as the trump suit. Next she cue bid clubs
and I bid 4NT. We use Roman Keycard Blackwood (four aces + trump
king) and her 5 bid showed three keycards. I
then bid 5 to ask if she held the spade
queen. Her leap to 6 showed the queen but no outside
king. I could now count thirteen tricks (five spades, six
diamonds, and two clubs) but the opponents held the heart ace. I
next bid 6NT to protect the heart king from the opening lead.
PLAY: West did not
lead the ace of hearts so I took all thirteen tricks. Note that 6 is
doomed with a heart lead. The convention helped us get to the
slam
but realizing the danger of a heart lead saved it.
