Planning

Recognise that RKCB responses may need judgment when responder has a useful void; avoid mechanical keycard counting.
A splinter convention in bridge is an artificial jump bid in a new suit that shows 4+ card support for partner’s suit, a singleton or void in the bid suit, and game-forcing strength. It immediately communicates hand shape and slam interest, allowing partnerships to evaluate fit

Final Comments

Looking at the hands, I see a club loser. It can be discarded on a good diamond, making a grand slam.
