I was sitting South and opened this minimum hand one heart in 1st seat:
Opponents were silent. My partner responded two clubs and my rebid was two diamonds.
Partner then jumped to three hearts, showing 3-card heart support and a slam invitational hand. My next bid was four hearts with my minimum.
Partner was still interested in slam and bid 4NT (Roman Keycard Blackwood 14-30). I bid five spades showing two key cards plus the trump queen. Partner then put me in a contract of six hearts.
Left hand opponent led the ace of spades and this was my dummy:
Recall my hand:
At trick two LHO made the excellent shift to the seven of clubs. Should I play her for the king of clubs? She is putting me to an early guess! I decided I cannot make the contract without finessing for the king of clubs, so I put in the queen and it won. From there it was a matter of setting up dummy’s clubs for a diamond pitch or two (being careful not to get overruffed).
