1♣-(1♥), 1♠(5-7 with 5 spades)-(3♥). The problem we had misunderstanding was, which bids are for spades, NF, and own suit.
My idea was that 4m-Natural,not too strong(inviting perhaps), 4♥Something like Choice of Game, 4NT-Good old RCKB, onesuited slam hands bid via X and then their suit.
My partner thought that 4m(same), 4H as cue for spades, 4NT as minors, and X and then something, dont remeber

Anyhow the bidding went on:
4NT-5♣, 5♦, 5♥-6♦-6♠-(X)-6NT down 2
6 Diamonds was making because partner was with a strong diamond suit. From what i though he was probing for a spade grand(good that i had diamond support i guess)
Anyhow the question i have is how do most people play these situations?
