Three Diamonds 5-5 in Majors

In a Nutshell

Playing minor-suit transfers (2 NT to clubs, 3 C to diamonds) leaves an idle 3 D response to 1 NT, which I use to show 5-5 in the majors (game forcing). An obvious advantage is to make 1 NT bidder declarer no matter which fit is found (opener sets trumps), plus it defines in one bid what otherwise takes two. Responder can next indicate his splinter with slam interest.

The 3 D response to 1 NT shows at least 5-5 in the majors and game-forcing values. This does not apply over 2 NT.
