When I was learning bridge, my late, dear mother often talked about captaincy as she bid 3nt over any opening bid I made.
In modern bidding, this notion that one partner is in control seems to have disappeared in all but keycard auctions.
No, that's not true. Anytime one partner has finished describing their hand within somewhat narrow limits, their partner effectively becomes captain of the auction. Anytime you do something like open 1nt/2nt or rebid 1nt/2nt limiting your range, or make a NF raise of partner's bid, you've effectively ceded captaincy to partner. They will control whether the auction continues, whether game/slam is explored/reached. They may inquire more information from you to make the decision. They may also show stuff about their hand so you can choose which game.
WasWinM's (not WinstonM, a long-time different poster) comment about captaincy in the other thread was nonsense. It has nothing to do with captaincy on that auction. It's an argument of which information should take priority and is most useful after partner makes an artificial forcing bid, and he's arguing for not so useful information to be shown while simultaneously removing room for partner to show the hands he's most likely to have at a convenient level. Captaincy is irrelevant, once opener bids 2d they have limited their hand and will never be captain. It's a question of what info for opener to show first, which also affects leaving room for responder to show their info so opener can cooperate initially to find the best strain for game.
