Finding a Slam
If the bidding or Losing Trick Count indicates that a slam is possible, it is important to identify whether the partnership is missing any aces and kings. This is usually achieved by using a slam asking convention such as Blackwood or Gerber.
With an ace missing a grand slam is unlikely and with a king missing it will be difficult
With 2 aces missing a small slam is unlikely.
It is possible to make a slam with aces and kings missing if the hands contain a lot of distribution (long and strong suits, voids, singletons). With distributional hands and a contract in a trump suit, it can be better to show controls by cue bidding.
