if you bid 5♠ with that, im happy bidding 6♦. if you bid 5♦, i pass. edit: if you bid 5♣, i bid 6♦ edit2: does my number of ♠ really matter? the number of options on this hand are so limited that i will either bid slam or not depending on if you cooperate. im happy saying 4NT is ambiguous and forward-going. the important thing is you have 5♣ to cuebid. with spades i think i'll likely bid an ambiguous 5♥. i admit this is completely esoteric, but what else can these bids mean?
