Suppose you decide to explore slam with RKC...partner bids 5S (two plus queen). Now what?
It was merely a practice session for my partner and I, so I decided to go for it...not sure if I would have done the same in a tournament.
For what it's worth, he had:
Partner opens 4S...what's your bid?
Down one on heart lead when West held A9xx of spades.
But the real question is whether it's crazy here to consider slam with the trump void? Any help appreciated...
