Partner wants to play 4♥ so he's unbalanced with nothing special to say, not ♠/4, no shortness... something like : (J)x A(J)x (D)x KQJxx and pick some cards to add in J of ♥ (likely in the hand for accepting), the Q or J of ♦ or the J of ♠ So, any slam will be risky : 6NT being the one with the best chances IMHO Alain
