The hand Sorry maybe this is in the wrong forum and I should put this in the natural bidding forum - I'm south on this hand. The auction: 1♣ - 1♠ - 2NT - 3♦ - 3♠ - 4♣ - 4NT - 5♥ - (2 keycards no Q) 5NT - 6♠ We reached the right contract, but my partner (who I'm playing with for the first time in a competitive tournament, and we are doing well - 2nd in our direction), disagrees with my 4♣ cuebid. I am of the school that cuebidding Q in partner's suit is fine, but my partner disagrees and only cuebids controls and thinks I should bid 4♥. Am I being immature/dominating the auction when I think cuebidding 4♣ is correct with the agreement we don't cuebid queens? From my perspective it seems 4 clubs leaves more room for both of us to express how interested we are in slam, even without a club K/A.
