If partner is light for his splinter then he should only have high cards in side suits, so i imagine we have no losers outside trumps unless clubs break 5-2 and partner only has 4 trumps (or 5 missing the Ace). If partner has AD then he must have trump A or K and an outside K (or the second trump honour), in which case slam is all but cold (AH and a H will likely beat it). The only other hand I’m worried about is: Xx AKxx KQTxxx X Or Xx Axxx(x) AQJTx(x) X I don’t see an obvious way to cater for these hands except to bid kickback and then perhaps Q ask to determine trump length. Even on the bad hands above there is still some play, especially on a trump lead which is quite likely. Here partner will show 2 with the Q and you know slam is an excellent bet.
